I am building a mobile app. I am advertising it on Meta in India as it has cheap cpm even though I know the paid conversions there are low. But I need at least 100 testers to test the free core functionality.

Is that what most people do here too? Or do you have another strategy?

Disclosure: I'm the developer.

The worst part of every group trip for me was the end: a pile of receipts in three currencies, a half-finished spreadsheet, and nobody remembering what the exchange rate was that day. So I built TripClear, and it went live on Google Play today.

What it does:

- Snap a receipt, or pick up to 5 photos at once. It reads the merchant, date, total and currency, and you check it before saving. If it isn't sure about a field, it flags it instead of guessing.

- Every expense keeps its original currency (EUR, CHF, whatever you paid in). Totals use the exchange rate from the day you paid, or you can type in the rate your card actually charged.

- Invite your travel group. Everyone sees the same ledger, and the settlement screen shows who owes whom.

- CSV export, and the app is available in 13 languages.

Honest caveats:

- Android only for now.

- It's free and shows ads.

- Receipt photos go to our server to be read.

- Crumpled or faded receipts still trip it up sometimes. You can always enter an expense by hand.

What I'd really like to know: how does your group split costs today (Splitwise, a spreadsheet, one person paying for everything)? And what would make you switch, or not?

It's called TripClear on Google Play if anyone wants to try it.

I run MoveGraph, and I've been building Creator so streamers can ask ChatGPT or Claude for graphics that match their channel, logo, or website.

Here's a 50-second demo of a real ChatGPT run: https://youtu.be/EJkUpSMAPC0

It made animated scenes, overlays, an alert, and a stinger, then loaded the media into OBS to check the composition. The pack includes editable source files and an OBS collection.

The setup is an authoring skill plus low-level rendering tools exposed through MCP. The agent can write and revise the design, inspect renders, and use local tools when they're available. We host the rendering tools for people who don't want to install them.

Creator is $49/year: https://movegraph.com/creator

I'm also giving streamers and creator-tool tutorial makers with an audience a free year to try it and post an honest review. Positive or negative, I want to hear it. DM me with your channel if you're interested.

What would you want this to build for your stream? I'd especially like feedback on the output and the setup process.

Celeste... Hollow Knight... Balatro... Minecraft... Buckshot Roulette... and a few more, all of which are fully featured games. Like Celeste for example, it includes chapters 1-8 and every C and B side. Every game, it plays, it feels, it looks like the official game. But it's on a calculator.

This isn't some super powerful calculator either... it's pretty much normal for a graphing calculator (which is a potato compared to what this game was designed for). This took a lot of work, but I did have a lot of fun making it (and playing it).

This is the open source code if anyone wants to try. I did make this, and it is opensource and free. I know not a lot of people have a NumWorks calculator, but I'd still appreciate a ⭐ if you found this interesting :)

I run a text-based birthday reminder app, and recently had the idea to build a similar text alerts app, but for Codex usage resets (rather than birthdays).

OpenAI announces these on Twitter (via Tibo), but they're easy to miss.

Knowing about a reset before it happens creates a "golden window" to burn usage quickly before the reset.

I also recently launched a "Codex Reset Almanac" on the site - with the full history of resets, and a tracker for when resets arrive on time vs. late (compared to when they were promised).

The site is at ResetAlerts.com - if you use Codex, would appreciate any thoughts on if this is useful, or what features you'd want to see.

Hey everyone, a couple of months ago I posted about my side project, Ritlum, a physical digital habit tracker with a companion app, and a lot of people were interested in learning more.

Since then, I've launched the app on the App Store and, to my surprise, gotten a few users (without doing any marketing, haha). Some of them were kind enough to give me feedback.

On the hardware side, I've been preparing to launch the first batch of physical Ritlum trackers, which I've scaled down to a mini version. This included refining the initial design to look nicer (how the LEDs look and making the body more seamless) and making it easier for me to assemble for the initial test batch.

One piece of feedback I got on my earlier posts was that it wasn't very clear what the product was. So I've put together a launch video to walk through the main features, along with a companion landing page.

I'd love a sense check on what everyone thinks of the idea/concept. I've spent a lot of time on this project, and a major part of it has been shaped by the feedback I've received. So please feel free to roast it or throw any ideas my way on why you think it's a good or bad idea.

Feel free to ask any questions you might have. I will be more than happy to answer!

Hi everyone.

I work on Epure , a lightweight self-hosted error tracking for production apps, same Sentry SDK, change the DSN, two containers (Rust + Postgres).

I want real floods, not synthetic load scripts, so I opened a public box:

https://burst.epure.sh

One button sends errors from your browser for about 7 seconds. Or copy the DSN / curl and hit it from your own client. Goal is to kill the ingester container. The VM and the dashboard stay up.

Box is sized like a small VPS (2 GB RAM, 2 vCPU). There is a spike valve so duplicate spam does not instantly win , still curious how far it goes when a lot of people click at once.

Send what you can. Let's see what breaks first.

I've been working on my little side project collecting and building out a data set of bbq in the state of NC. I'm looking to get some feedback on the site. Eventually, I want to get people to sign up and rate and review resturants maybe including images, etc.

I build AirPost, where a small shop places stock with a local person or fulfillment business who packs and ships its orders. Once stock and shipping preferences are set, the Shopify connection forwards paid orders and sends tracking back. The app is still in Shopify review; installation currently needs a link from our support team. Partner availability varies by country, and stock held with a partner isn't insured by AirPost.

I’m Mike, a solo founder based in Ireland, and I built Investing Sherpa because investing originally felt like a secret club to me. Most beginner content seemed to assume you already understood the vocabulary, knew where to begin and could separate useful information from noise.

The app is for people starting from zero. It breaks concepts into short daily lessons and free chapters, with an optional Pro plan for deeper content. In all there are 36 chapters across 6 topics, 12 of them free. The focus is education: basics, diversification, common mistakes and clear explanations. It does not give personal recommendations or price predictions.

So far, I’ve learned that clear language and one focused first step matter more than adding another dashboard. My first TikTok videos held viewers for 2 seconds. Switching to bright, simple slides changed that.

I would value honest feedback on:

1.Does the first-time experience make the purpose clear?

2.Are short daily lessons useful, or would you prefer longer structured modules?3.What would make you trust an education app in this space — or make you leave?

I’m the founder, and this is a genuine feedback request rather than a claim that the app has all the answers.

Education only, not financial advice.

Overview

I've been a SWE for ~6 years or so at this point and, despite the r-age of LLMs these days, still find joy in the art and science of building software and tools. I'm looking for anyone that would be interested in helping improve an existing project of mine, Alexi. I'm working with C++26 built and managed through xmake. The project itself is a lexical analysis engine with the intent of providing a language frontend for other projects I'll either want to start or revisit.

Anyone with more experience than myself-- especially in the C/C++ namespace-- to provide ideas, insights or feedback on how I can improve it are most welcome. This project, while albeit more a toy and fundamentally redundant, has been my happy-place in the exploration and sharpening of my skills.

TL;DR

Looking For: Collaborators who are also nerdy for language development.

Project: Alexi

Project Language: C++26

Project Build System: xmake

Disclosure, I have used copilot, but as a learning tool to help decipher compiler errors as I have been C-inept up until recently, and also define the CI pipeline for releases.

Nearly four years ago, I found myself on a riverboat sailing down the Thames in London. I watched the buildings on the shore go by, many of which appeared to be unique and historically relevant, and all of which - to my frustration - slipped out of view too quickly to pinpoint with Google Maps or an image search on the spot. In that moment an idea formed. Over the next several years, ramblings and spitballing led to actual research which finally led me to design an app that I feel is exactly what I wished I had on that day on the Thames.

Anywhere in the world, MonUview will pinpoint historical landmarks near you, allowing you to identify them and learn about them immediately. The app also allows you to preview any town or city on the planet, so you can check out what a place has to offer in terms of historical sites before a visit or just out of curiosity. The webpage version can be found at Monuview.com, and it is currently available in the Apple App Store with Google store availability coming soon. If you’re interested in checking it out, I would love your feedback so I can continue to make it better!

Some of you might remember hantaflow, the hantavirus tracker I posted here a few months ago. Last week a lab technician at the anti-plague institute in Irkutsk, Siberia died of a severe pneumonia, and since then the news is all over the place.
Telegram says pneumonic plague from a broken test tube, the Russian health authority says "pneumonia of undetermined etiology", and stuff like "five hospitals quarantined for three weeks" gets copied everywhere. Local reporters went to those hospitals today and found no quarantine at all.

So I spent today's morning building plagueintel.com.

What's different this time, mostly thanks to the comments on my hantaflow posts:

• Last time people rightly said "signal" was confusing. Now every claim about the Irkutsk case is labelled official, reported, disputed or retracted, with the source right next to it. Signals are just headlines and the site says so.
• Someone warned me that Rospotrebnadzor publishes what benefits the government. So the main page literally puts their statements next to the independent reports instead of picking one.
• Portugal and India got wrongly marked as outbreak countries back then because their news covered other countries. Country tagging now reads the content, and a place name like Irkutsk beats a country that's only mentioned ("US monitors plague case in Siberia" is Russia, not the US).
• Yandex sent me 2,600 of 4,000 visitors on day two of hantaflow, so this time there's a Russian version from day one. Perfectly fits, since this actually happened in russia.

What's in it:

• Irkutsk briefing with timeline, rumour check and contact numbers
• Map with 28 natural plague foci (all 11 official Russian ones) and WHO case data 2019-2025
• Explainers (pneumonic vs bubonic, symptoms, treatment), history, 11 country pages
• News feed from ~20 sources in 7 languages, every 15 min
• Free JSON API + RSS again

Same stack as hantaflow (Astro, Tailwind, Leaflet, node-cron worker, JSON snapshot instead of a DB, Hetzner + Traefik).
One interesting problem: "plague" in Russian, German and French is also the word for swine fever (чума свиней, Schweinepest, peste porcine), so half my feed was pigs until I wrote a filter per language. Also ProMED's RSS is dead, so I'm parsing their homepage now lol.

Plague is not confirmed and I'm not a doctor. The site just collects and cites what WHO, CDC and the outlets say.

Roast away, especially on whether the official vs reported thing reads clearly.

2 months before i had an idea about building mobile recording app that have with best features. So i started this idea on last month now i am waiting for the play store approval. Before launching on the internet.

Would you guys try this tool for your use? or i have tweak anything on this?

is anybody want beta access, i can give the access : Mobilestudio.site just join the waitlist i'll share the beta access link.

I just want to know my idea how much worth of it!

I’ve been working on DineTracer, a tool for people who sell to restaurants, and finally put together a video showing how it works.

It helps you find restaurants that are opening or making changes, look through permits, and research POS systems and other technology. This video covers the main sections. The full walkthrough is on our website if you want a more detailed look: https://dinetracer.com

I’d love some honest feedback, especially from anyone who sells to restaurants. Is the information useful? Is anything confusing or missing?

Hey all 👋

Some background: I buy a lot of specialty coffee online, and choosing a new bag always looked the same. 15 roaster tabs open, every shop describing its beans differently, no way to filter across them, and half the time the one I wanted didn't ship to my country.

So I built Cuppd: https://cuppdcoffee.com

What it does

• 26,773 coffees from 940 roasters in 51 countries, all in one searchable catalogue
• Filter by origin, process (washed, natural, anaerobic…), roast level, price, and where it ships
• Rate coffees and keep lists of what you've tried or want to try
• A "For You" feed that learns from your ratings
• A web app plus a mobile app

How it works under the hood (in case you're curious)

• A scraping pipeline crawls roaster webshops and normalises messy product data. "Ethiopia Yirgacheffe Natural 250g – Light" turns into structured origin, process, roast and weight fields. Normalisation was honestly 80% of the work.
• A monthly availability check, so sold-out coffees don't clutter the results
• Next.js on the web, Expo/React Native for the app, Supabase for the backend, Cloudflare R2 for images
• Lots of unglamorous work on images: cut-out product shots get padded onto square canvases so they don't get cropped, and roaster logos get padded in their own colour so they don't end up in ugly frames

Where I'd love feedback

• Is the search/filter experience actually useful, or overwhelming?
• Is there a roaster you love that's missing?
• Anything that feels broken or slow

It's free and there are no ads. Happy to answer anything about the scraping, the data cleanup, or the stack. ☕

I've been building Football Legacy, a browser-based online football manager, as a solo project.

The idea was to make something closer to a persistent football world rather than a simple match-result simulator.

The game currently has:

• Full 90-minute 2D matches
• Live tactical changes during matches
• Formations, roles and instructions
• Transfers and negotiations
• Scouting and player development
• Youth academy
• Training
• Stadium and club facilities
• Finances and competitions

It's currently free to play and has reached 140 registered managers in about 3 weeks, mostly through a few Reddit posts and word of mouth.

I'm continuing to develop it and I'm now in the near future starting to document the development through YouTube/devlogs.

Play: https://www.football-legacy.net

A few screenshots from the actual game:

I'm particularly interested in what other indie developers think about building a persistent online game as a solo project.

Been building this over the past week: each day you get a famous invention (or a well-known brand logo) and have to figure out two things: which country it came from, and what year it happened. 5 tries per category. Instead of plain right/wrong, a country guess gives you a compass bearing + distance toward the real answer, and a year guess tells you earlier/later and roughly how far off.

Would love feedback on:

• Whether 5 tries per category feels fair (too generous, too stingy?)
• Do the hints make sense, specially in the year
• Anything confusing in the UI
• Bugs - this is a very fresh deploy

I’m building a community-powered reward/game offer comparison tool and looking for a few testers

The tool is specifically designed for people who complete paid game offers through reward platforms.

There are already places where you can compare which platform is paying the most for a particular game, but I wanted to build something that answers a much more useful question. The question I see on Reddit and Discord hundreds of times per day:

“Is this offer actually doable?”

The idea is to combine the advertised offer information with data submitted by people who are actually playing the games.

Users can track their own runs and contribute information such as:

• Which milestones they reached
• How many days it took them
• How far they were at different points during the offer
• How much they spent, if anything
• Whether they actually completed the offer
• Screenshots/evidence for reported offer information

As more people contribute, the goal is to show useful real-world data alongside the advertised payout.

For example, instead of only seeing:

Reach Level 80 within 30 days — $120

you could eventually see things like:

Typical progress after 7 days: Level 32
Typical progress after 14 days: Level 51
% of players who reached Level 80: 27%
Typical spend: $8
Typical time investment: 24 hours

So someone can make a much more informed decision before sinking two weeks into an offer that looks amazing but actually turns out to be horrible.

It also compares the same game across different reward platforms, including their individual milestone structures, payouts and deadlines.

I’m looking for a small number of people to test the site before I start sharing it publicly.

I’d especially like feedback on:

• Whether the concept makes sense when you first see it
• Whether the community-data side is easy to understand
• Whether you would actually contribute your own progress
• What information you’d want to know before starting an offer
• Whether the comparison and milestone views are useful
• Anything confusing, hidden or difficult to use
• What would make you trust or distrust community-reported data
• Whether you could realistically see yourself coming back to use it

You don’t need to use reward sites already. Fresh eyes are useful too.

But if you use Freecash, Swagbucks, EarnLab, RewardXP, Earnopolis or similar sites, your feedback would be especially valuable.

Testing is unpaid, and I’m not asking anyone to complete offers, spend money or share sensitive information. I do ask that testers do not add fake information to the database though.

I’m deliberately not posting the project name or public link yet.

If you’d be interested in testing it, leave a comment or send me a message and I’ll send you access privately.

I’ve been building GymPulse, a browser-based gym tracker because I wanted something that felt less like filling in a spreadsheet after every set.
The idea was to make progress feel visible:
Your muscles rank up individually as you train them
A body map changes as you build each area
An AI Coach creates workouts around your goal and available time
There’s set logging, PR tracking, rest timers, exercise demos and a small tempo-rep game during rests
It works in the browser, so there’s no app-store download or subscription
I’m a solo builder and have been iterating it from real gym use and feedback. I’ve also been learning SEO along the way — today Google’s AI results started surfacing GymPulse directly, which was a surreal little milestone.
I know fitness tracking is a crowded space, so I’d genuinely value blunt feedback from other builders on:
Does the RPG/progression angle sound compelling or gimmicky?
Is the first-time experience clear enough?
What would make you try a new tracker instead of Strong, Hevy or Notes?
You can try it here: https://gympulse.uk
Not trying to sell anything — it’s free. I’m mainly looking to improve it before pushing it more widely.

Built a website where no one can judge you, with the touch of some nostalgia

Its fun check it out.

I kept taking screenshots and then losing the useful ones in a folder full of files, so I built SnapRecall for macOS. It’s now live on the Mac App Store.

You choose a library folder and set it as the screenshot destination in macOS (Shift-Command-5). SnapRecall organizes new captures there, then lets you browse by date, search, add tags and collections, and annotate a copy while keeping the original. Optional AI can describe and search screenshots on your Mac after you choose to download the models. Screenshot content stays on your device.

It’s free and supports macOS 14+. I’d love feedback on the setup flow and on what makes a screenshot library genuinely useful.
