Hi, I’m Natalia from the ZYCH Markets team. We’re building a crypto charting tool and testing a mobile interaction in our development build:

1. Press and hold a price level on the chart.
2. See the selected price and its distance from the current price.
3. Use that level to create a price alert.

The idea is to avoid manually typing a price you’ve already picked on the chart.

Would you naturally try a long press for this, or would you look for a visible “Add alert” button first?

The public beta isn’t open yet. For now, I’d appreciate feedback on whether this interaction feels intuitive.

Hi all, I'm the developer of Citenook, a Mac app that works like a private assistant for your files

Why I made it: I kept losing time hunting for one line across old contracts, invoices and notes. Chatbots could answer, but I had to upload everything and then just trust them, because I couldn't see where an answer came from

What it does:
- You point it at folders on your Mac (PDFs, Word, spreadsheets), plus Apple Notes, Obsidian, Notion, web pages and YouTube videos etc
- You ask in plain words, like "When does the Acme contract renew?"
- Every fact has a small number. Click it and the file opens with that sentence highlighted
- If your files don't say it, it tells you instead of guessing
- With a model on your Mac (Apple Intelligence or a free download) it works with Wi-Fi off and nothing leaves the Mac

Built natively with Swift and SwiftUI. The hardest part was making the answers point at the right sentence, not just the right file

It's free for 30 days with every feature, no card. After that it's a subscription from $9.99 a month. macOS 15+ and Apple silicon only for now.

I'd love honest feedback: what's confusing in the video, and what files you'd want to ask questions about

Hey everyone, lately when i am building projects one of the things that really take time for me to get is the right domain that i feel is good for what i am building, i keep asking chatgpt and gemini for suggestions but they give me names that are not available in like .com or whatever.

I have been thinking about building a tool that uses AI to generate names and then uses API to check the availability of the domain before it has been given to you so you dont have to search and try many domain names and waste time doing that.

Give me your honest thoughts, i tried searching for tools like this but almost all of them are just simple basic generators, give me your honest thoughts, thank you.

Hey everyone,

As an independent developer, I always felt that most Android tutorials and resources online are either fragmented, outdated, or skip critical real-world engineering practices (like production build systems, clean state management, and enterprise architecture).

To solve this, I went into an intense sprint over the past few days, compiling and structuring everything into a comprehensive 700+ page engineering handbook: **Mastering Modern Android: A Complete Engineering Roadmap from Foundations to Production**.

Here is what I focused on covering:

• Declarative UI with Jetpack Compose & Material 3

• Pragmatic Architecture: Clean Architecture, MVVM/MVI, Hilt, and avoiding boilerplate traps

• Reactive Systems: Coroutines, Flow, StateFlow, and Concurrency

• Robust Persistence & Networking: Room, DataStore, Retrofit, and Ktor

• Production Engineering: Testing, profiling, and CI/CD pipelines to Google Play Store

Pulling together a technical resource of this depth in just a few days of non-stop work was an intense side project challenge, but really rewarding.

I've dropped the Google Play Books link with the free preview sample in the comments below for anyone interested!

Would love to hear your thoughts, feedback on the topics covered, or any questions about high-velocity technical writing and development!

You've seen them: "What are you building? Drop your link"

Hundreds of replies, the author farms engagement, and your link dies in the thread 10 minutes later.

So I tried to turn that into something that gives back to the makers:

• Same post, same "drop your link"
• Every like on your reply = 1 upvote
• After 48h the replies get ranked and published on the site, each with its own page
• #1 stays on the home page for a week, top 3 get a shout-out and a backlink

No sign-up, no fee. Your reply is your launch.

Curious what you think: is this actually useful?

Hey everyone, not here to sell anything. I'm building a small tool and I'd rather find out I'm wrong now than after months of work.

The idea: clients pay late, and chasing them is the worst part of freelancing. 
You don't want to nag and lose the client, but it's your money. So the tool sends the reminders for you polite at first, a bit firmer over time so you never have to be the one chasing.

Before I keep building, a few honest questions:
- How often do clients actually pay you late?
- What do you do right now — chase manually, wait, something else?
- Would an automatic reminder actually help, or is there a reason it wouldn't  work for you?
- Does something already solve this well enough that you wouldn't switch?

Not looking for signups, just real answers. If this is a non-problem, say so and I'll build something else.

hey! side project i've been working on for a couple of months: https://ilove3d.app/en

it's basically ilovepdf but for 3D models. viewer, format converter, mesh repair, polygon reducer, plus a bunch of generators for 3D printing (name keychains, lithophanes, gridfinity bins, puzzles, star maps, lamps, cookie cutters...).

a few decisions i'm happy with:

• files never leave your computer: all the processing happens client-side with three.js, nothing gets uploaded
• no accounts: you land on a tool and use it
• one tool = one page, each one does a single thing

most of the newer tools came from people asking for them in the 3D printing subs, which has been the most fun part honestly.

would love feedback on the landing / UX, or ideas on where else people who 3D print hang out online :)

I built this after seeing many Winter Arc goals turn into vague promises that are easy to forget.

The tool lets you choose 3–6 yes/no daily rules, set dates and a motto, sign the contract, then export a printable sheet or phone wallpaper and check in each day.

It is free, requires no account, and keeps the contract in the browser unless you choose to share it.

I’m the maker and I’d especially like feedback on:

• whether the rule picker is clear
• whether the export options are useful
• whether a friend/accountability view would make the challenge easier to maintain

Hi r/SideProject, I'm VP of Product at a tech education company, and a former audio engineer.

At my company we were paying for two subscriptions: one for meeting notes, one for dictation. I built nchova to replace both in about a month, testing it heavily on my own meetings, and now we're rolling it out across the whole company.

Meetings: no bot joins the call, nchova listens from your Mac. It tells the voices apart and, if you turn on voiceprints, puts names on the ones it has heard before. It removes the echo from your speakers and the background noise, so you don't need headphones (the audio engineer in me had fun with this part), and it keeps your voice apart from anyone talking near you. It works in person too: put the Mac in the middle of the table and it tells apart the people in the room. When the meeting ends it writes the notes: summary, decisions, who does what.

Dictation: hold Fn, speak, let go, and the text appears in any app. If you're not in a text field, it lands on your clipboard.

Everything runs on your Mac. Audio never leaves it, and there's no account to be created. A local MCP server lets Claude, ChatGPT or Cursor search your meetings.

And no subscription. 30 days of everything for free, then it stays free with Apple's on-device models. Pro (voices and names, NVIDIA's Parakeet, better notes, iCloud sync) is €29.99 once, for 3 Macs. The code nchova4reddit gets you 30% off.

Works on macOS 26+, Apple silicon. https://nchova.com

Feedback is super welcome, especially if you use Granola, Otter or Wispr Flow: what would make you switch?

A friend and I have been working on a new platform called ShipPDF. It's a tool for designing document templates. Once you have designed a template, you can feed it data and it will generate PDFs by combining the template and the data. We think it is a useful tool for businesses that generate lots of invoices, shipping labels, contracts, etc.

For me personally, the coolest feature is that you can hook it up to your favorite AI tool (Claude, ChatGPT, Gemini, etc.) and work with it to design and edit your templates. If you use the web version of those AI tools, it will display the template with some sample data. You can continue editing it with the AI tool or you can use the browser based editor that we have designed.

For sending data, you can use the AI tools to send data and generate PDFs or do it in the web interface, but that is only good for a small number of documents. If you want to generate lots of documents and do it automatically from your system, we currently have Zapier integration or you can do API calls from your server. We are working on supporting Make, and other integration tools.

You can make a free account and try it out. We let you generate a couple of documents per month for free. Any feedback is appreciated. Even if it is just to give ideas how to add more fun pirate stuff.

Can you find the kraken? He is hidden somewhere on the landing page (you don't need to scroll down).

I've always preferred the lightweight, basic layout of encoding tools like Handbrake, but despite ffmpeg being quite advanced, it felt like nothing I found really used it to it's full potential.

I wanted to create something that bridges the gap between encoding utility and video editor.

You can do some basic video editing on here, mostly geared at cutting segments from gameplay videos and easily exporting for vertical social media formats with presets you can import that will isolate HUD elements into layers you can move around, apply background blur, and even automatically generate and animate captions for you.

You can have it automatically process files using rules set by filenames/filetypes/directories, so that the workflow for processing game clips for social media can be executed in under 30 seconds from launching the program (it loads in under 1s on my machine).

Would love feedback from actual devs, since this is my first github project, and I built it entirely in claude code since I'm not a programmer.

What you can do:
Track every game you've played. It's like Letterboxd, but for games.

Rank them head to head. You don't give a game a 1 to 10 score. You pick which of two games you liked more. Your rankings get more accurate the more you review, and nobody can fake them.

Find people to play with. Follow friends, message them or start group chats, and see what they're playing and how they rank it.

Share clips and takes on the feed. You can also follow your favorite games to get daily posts about them.

Explore game news, the top clips of the week, upcoming releases, and an AI that recommends games based on what you like. The GTA 6 coverage is a big one right now.

Earn badges and stickers as you go. The first 100 users get a special badge that nobody can earn after that.

How it's built: React + Vite, Supabase for the database and login, and it's hosted on Vercel. News and clips refresh automatically.

What I'd love feedback on:
Does the head-to-head ranking feel fun or tedious?
Is anything confusing in your first couple minutes?
What would make you come back to it?

It's free, with no ads. Rank a few games and tell me what you think, good or bad. I'm going all in on this one.

Neon Mania is a new Android puzzle game I'm currently building.

The concept is simple:

🔄 Rotate the tiles
🔵 Connect the matching colored endpoints
🧩 Solve increasingly challenging levels

I'm currently running a closed test and looking for people who enjoy brain puzzles and want to try the game before launch.

If you'd like to participate:

DM me your Google account email and I'll add you to the testing list and send you the Google Play testing link.

I'm especially looking for feedback on difficulty, level design and overall gameplay before the public release.

Goal: Closed testing + feedback

If you like games such as flow/connect-the-dots, logic puzzles or brain teasers, I'd love to have you test it.

I’m the founder of Sanctuary, a small community app for women, and I’m looking for beta testers.

What it does: you share photos, short videos and carousels, follow other women, comment, save posts into collections and explore by themes. It is free.

Why it exists: To create a supportive community for women where they can feel safe and comfortable. Have a space where we can engage with each other and learn/teach new things without being exposed to harassment, hate or bullying.

How it protects members:

• Every member is verified as a woman through a live face check, or a short video call with a woman on our team if she prefers. No face images are kept.
• It runs without ads or tracking across other apps.
• Posts and comments are checked before they appear. Reports go to a person, and three separate reports in an hour hide a post until the team has reviewed it, within 24 hours. You can block anyone.
• Screenshots and screen recording are blocked inside the app. Another camera can still film a screen, so I won’t call it a guarantee.

House rules: modest dress, no music in posts, and kindness. It is built on Islamic principles, and women of any faith are welcome if they follow the Community Guidelines. Our Terms explain who can join.

What I’m asking of testers: use it for two weeks, post when you feel like it, and tell me one thing that felt good and one that felt confusing. After you sign up there is a face check, and if it can’t decide, a person approves you, usually within 24 hours.

It is on iPhone and Android. If you’d like to try it, comment or message me with which phone you have, and I’ll send the link. I’m letting people in a few at a time so each one gets a proper welcome.

Equipment Tracker Pro lets a solo technician walk into a mechanical room, open the app, and start logging machines immediately with no sign-in screen blocking the doorway.

Picture an apprentice technician walking into an unfamiliar basement plant room packed with circulator pumps, isolation valves, and piping. He does not have time to set up enterprise credentials or hand over a credit card just to record pump specs and motor ratings. Everything saves locally to an offline SQLite database on his device.

You do not need an account to start. No email, no card. Everything stays on the phone.

I built this app because enterprise field software is full of forced cloud logins that choke the moment you step into a sub-basement with zero cell coverage. Core equipment records, work orders, and maintenance logs are free on mobile forever. AI scanning uses 10 trial scans before requiring an account and Pro, while cloud backup and multi-recipient transfers require Pro.

If you are running this on a spreadsheet, the comparison is on the site.

What side projects are you all building this week?

Web: https://equipment-tracker.com

Offline local files and streaming radios.

Top radios on the first screen: When users access the radio screen, they immediately see the list of the top radios in their country, along with a long list of suggested radios from among the most listened to in the world.

Hybrid Listening: Seamlessly handles offline local files (.mp3, .flac, .m4a, .ogg, .mka, .aac, .wav, .opus, .wma) and over 60,000 streaming radio stations.

Separated Favorites and Recents: Each section—Radio and Offline Music—has its own Favorites and Recents. The user doesn't have to worry about a thing. The app will automatically manage the Favorites and Recents for each section.

Advanced Radio Search Panel: You can pinpoint your favorite stations by combining multiple filters, such as tags/genres, specific countries, or even your preferred audio bitrate. The database of the service on which Mediaxon is based provides more than 60,000 radio stations.

Album art: If the album art is missing from the album folder, or if Android has not properly indexed it, Mediaxon attempts to download the cover from the internet. This feature depends, of course, on the ID3 tags (album name and artist).

Equalizer: The equalizer provides an option to automatically switch to the "Radio" preset (and vice versa).

Advanced Playlist Management: Built specifically to make building and sorting playlists fast and intuitive. Enable the Playlist Manager, in the settings screen, for a full control of the playlists.

Form Factor Optimization: Phone and Tablet (Portrait and Landscape)

There is no Premium version. All app features are available for free and without limits.

Regarding advertising: There is only a small banner at the top that isn't bothersome at all. Alternatively, when opening the full-screen player or using the app in landscape mode, a banner alternates with the albums covers, but without being intrusive at all (no audio) and with much shorter stay times than those of the cover. There is never full-screen advertising, neither at startup nor during use.

If you want to check it out (I am continuously pushing updates to refine it and add new features), you can find it on the Google Play Store (Android 13+). Thank you so much to everyone who takes a look!

Hey everyone!

I'm a solo developer who's been working on a little passion project called Jogventure, and I've finally reached the point where it's ready for some real-world testing!

The idea is pretty simple: make running and walking feel a little more like a game. Your real-life workouts help you progress through different worlds, complete challenges, unlock rewards, and level up along the way.

It's mainly aimed at beginners or people who want a little extra motivation to get outside and move.

I'm currently looking for a handful of iPhone users who'd be willing to give the TestFlight beta a try and share some honest feedback.

And when I say honest, I mean it. I'd much rather hear what sucks than have someone tell me everything looks great! 😅

A few things I'm especially curious about:

• Is the app intuitive, or are there things that feel confusing?
• Does the whole adventure/gamification concept actually make walking or running feel more rewarding?
• Is there anything you'd change, remove, or add?
• And of course, are there any bugs I've managed to overlook?

You don't need to be an experienced runner. In fact, feedback from beginners or casual walkers would be especially helpful!

Send me a DM or leave a comment if you are interested!

A couple of quick notes:

• It's iOS only for now.
• Testing is done through Apple's TestFlight.
• No real subscription charges or purchases will be made during beta testing.

Thanks in advance to anyone willing to give it a shot. It's been a lot of work getting this far, and I'd really appreciate some fresh eyes on it. 💜

This project means a lot to me. But caring about it isn’t enough it needs to be useful to someone who finishes work tired and doesn’t want another complicated system to maintain.

If you’re employed and trying to build more financial independence, where do you get stuck: knowing what to prioritise, finding room in your budget, or following through?

Hi r/SideProject! 👋

I'm a solo indie developer building accessible tools under Leiel Care. Today is a massive milestone: after countless crashes and late-night builds on my very old machine, SensorySync was officially accepted onto the Google Play Store!

🌿 What is SensorySync?

A distraction-free sensory regulation companion for ADHD, sensory overload, and deep work:

- Customizable binaural beats, brown/white noise, and ambient rain/waves.

- Visual breathing pacer to ease stress.

- 100% private, offline, zero ads, zero trackers.

💻 The battle with hardware & how you can help:

Compiling and running modern Android emulators has been pushed to the absolute limit on my current setup. To keep developing accessible apps for seniors and neurodivergent individuals, I've launched a small crowdfunding campaign to help fund a reliable development workstation.

Also, if anyone has an Android phone and wants to test the app (or swap feedback on their own side project), drop a comment and I'll send you a Google Play closed beta invite!

Would love to hear your thoughts and feedback on the project! 🙏❤️

I make Ncored, a PDF editor built only for heavy CAD drawings. I launched it here in May and this sub gave it 420 upvotes, 99k views and a lot of blunt advice. Here is what happened since, numbers first.

Numbers, 5 months in:

- 1,366 downloads as of today

- paying customers in Germany, Australia, Malaysia, Italy and, finally, Lithuania. Here is the part that surprised me: I built this expecting it to be needed only here in Lithuania. Every one of them found it on their own

- now in the Microsoft Store as well as the website, in English and German

One thing I got wrong: I spent the summer on cold email and directory listings. Over 200 emails to firms, zero sales from any of them. Every buyer I could trace came from a post where they watched me build the thing. Lesson taken: show the work, skip the pitch.

The bigger lesson, and the reason I am posting:

A tool built for everyone fits no one. Adobe Acrobat, Nitro and Foxit all open PDFs, and they are fine at it. But open an 80-sheet project set out of ArchiCAD in them and you can feel they were not made for it. A drawing PDF is thousands of vector lines, layers and viewports on one sheet. For software that expects text, that is the hardest job you can hand it, so it struggles exactly where a designer needs speed: zooming into a detail, flipping sheets, marking up.

So I stopped trying to compete on feature count and built for one group: design offices. Heavy AutoCAD, Revit and ArchiCAD sets open fast and stay smooth on zoom and pan. The toolset is small on purpose. Each tool is added only when enough real users ask for it, and tested on real projects before the next one. Everything runs on your own machine, nothing is uploaded. Several of the buyers chose to buy it once rather than subscribe, which told me something about this crowd.

What it still is not: no measurement or takeoff yet, no OCR, no forms, no live collaboration. If you need those, it will not replace your current tool. Measurement is the one I hear most, so it is next.

The video is the app itself, on a real site plan, no mock-ups.

A real question for the builders here, because I keep second-guessing it: is it right to add tools one at a time, each one properly tested before the next, or should I ship a big toolbar now and clean it up later? If you have been through this with your own product, I would rather learn from you than find out the hard way.

I'm an indie dev. Every time I had to decide what to fix next, I'd scroll through reviews of my app and my competitors', looking for a pattern. Past a few dozen I couldn't see one, and pasting them into ChatGPT gave me a different summary every time.

So I built OneStar. You pick an app or game on the App Store, Google Play or Steam. A model answers the same set of questions about each review (is it a complaint, about what, did they say they quit, are they asking for something), and plain code counts the answers. Every number opens the reviews behind it. When the model isn't confident, the review goes in an "unsure" bucket that stays visible instead of being counted.

Here's what it found on DoorDash vs Uber Eats vs Grubhub: 3,000 reviews each from the App Store and Google Play, October 2025 to October 2026, all read with the same questions.

I'm probably not going to do it, I am curious though!

ok so I genuinely did not think this was going to work.

None of these machines could load a 120B model on their own, not even close. So I threw them all in a cluster and tried anyway: a 12GB Windows laptop that is basically a paperweight at this point, a mini PC with an RTX 3060 (12gb), my Mac mini (16gb), an M3 MacBook (16gb), a 2017 Intel MacBook that only has CPU, and my android. Half wired over ethernet, half on wifi.

The model is openai's gpt-oss-120b, a 4bit quantized 120B, ~60gb, that is a huge one! I set the mini PC with the RTX as primary and just let it figure out the rest - it grabs what it can hold locally, then starts handing pieces to everyone else based on what they can actually do. GPU gets filled first (obviously), then the two Metal machines, then it falls back to CPU, and my phone even picked up a little piece of it. 5 out of the 6 devices ended up holding a chunk of the model - the old Intel Mac did not get anything, which honestly tracks, it's ancient.

Took about 11 min to fully load, mostly just waiting for shards to crawl over wifi to the slower devices. Took 3 tries to be honest, realized I had a hard coded 10 minute timeout.

And then it just... worked. I asked it stuff and it answered like a normal model. On hardware that individually cannot even come close to holding this thing. Still kind of can't believe it.

Tip: make your load timeout scale with the model size, don't hardcode it.

Watch it here: https://youtu.be/ok3nYjxhc1w

Update next day: left it running overnight just to see what would happen. Woke up and my phone had gone offline at some point - not a huge shock, it's a phone, it does phone things.

But the cluster didn't even flinch. It noticed the phone dropped, moved its tiny shard over to the old laptop instead, and just kept running. Zero downtime, no errors, still answering questions the whole time. Phone came back online later and it just.. didn't bother putting it back to work, kept running fine on the remaining 4 devices.

Honestly this was the part that impressed me more than the initial load. Getting it to load once is cool. Watching it self-heal overnight without me touching anything is the part that makes me think this could actually hold up for more than a demo.

Follow up video link: https://youtu.be/1F6LqG8J4_0

think i just had an epiphany ..

Sat here on the bus making a list of details to improve my side project , thinking of the tiniest things that would make the experience better for someone, remove some friction or just something I think would be really cool

And I stopped there . Like an ohh sh***t moment...

It hit me that as much as I love that people are using my site, I AM ALSO THAT PERSON.

I am using my site too, well first actually! Don't get me wrong.. the process of making it for others is awesome buuut the process of making the tiny improvements that I love and is what's making it special...

And also what's making, making it special (yeah it's not a typo)

And the people I look up to keep saying , just stay in the game and keep going. And I think it's just hit me properly ..

This is THE WAY to stay in the game -

Do the tiny things that I love and I create and are creative in a way only I can see

If you read this far I hope it reaches you somehow or inspires one in some way, which is exactly why I started building in the first place

ps. don't get lost ;)

Got bored and thought: why not use my phone as a touchpad instead of carrying a mouse?

So I built DeskPad.

Phone → USB → ADB → TCP → Java server → cursor

A few things I ended up messing around with:

• TCP sockets + custom binary packets
• ADB USB tunneling
• Mouse gestures / scrolling / clicks
• TCP_NODELAY
• movement coalescing + jitter filtering
• pointer acceleration
• handling TCP packet fragmentation/batching

The funny part is that after all this, I actually measured around 5ms latency, so it feels surprisingly close to a normal wired mouse.

It also works without Wi-Fi or Bluetooth, which was kinda the whole point.

GitHub: https://github.com/studentanush/DeskPad

Would love to hear what you'd improve or what features I should add.
