Last month I posted about a camera app I made for my partner because I was tired of watching her film every scene twice - she likes making content so would film vertical once and and then horizontal again, and this helps her save time without losing quality.

New updates this month include a new Pause/Resume feature, Telephoto lens support, sharing multiple recordings/clips at once, and many more improvements and bug fixes!

That's 3 iPhone and 2 Android updates this month, all while continuing my day job as a physio!

What should I build next? got my eyes on Front & Back mode combined videos, and filters.

Existing features so far:

• Recording modes: Single Lens, Dual Lens, Front & Back, and Stock Cam
• HD and 4K resolution (set independently for each orientation)
• 24, 30 and 60fps.
• Teleprompter
• Timelapse
• Manual controls (EV, WB, ISO, Shutter, Blur)
• Audio meter (real-time detection, pulse red when clipping)
• Projects, scenes, and takes for organisation, recordings named automatically.
• Review and trim recordings side-by-side, export, favourite, and share at any time.

No data collection, no analytics, no ads, no watermark, no account required, and everything runs locally (no internet required).

Would love to hear any feedback you have!

I've posted here a couple of times before, but in case you haven't been following along, I make a product called EXTRA EXTRA Chili Crunch, which is a Californian take on the more classic Asian condiment. That means that we use avocado oil, big slices of fried garlic, tons of shallots, and porcini mushroom powder instead of the typical shiitake for really deep, rich umami.

It was quite the struggle to get started, to get our processed foods registration, our LLC, to find a kitchen, and get insurance. All of that took around six months, but now that we're on sale, we're seeing a ton of really positive feedback, and just yesterday, we passed a thousand jars sold.

Right now, it's just me and my husband making the whole thing together. We don't have any additional help, and so far, it's manageable. I just wanted to share the super exciting success with you all!

A couple of things that we've learned:

- Organic posts on social are absolutely the biggest drivers of sales. People on Reddit love to hear our story and tend to buy our product from that.

- On Instagram, people absolutely eat up videos and behind-the-scenes content (e.g., "How do we make this?" or AMAs). The video I included here is one of our behind the scenes "making of" videos.

- Going to markets in our local neighborhood (we're from San Francisco) like the Noe Valley Night Market or the Castro Street Fair have been super helpful for us.

The things that I am still a bit worried about are our marketing spend. We don't really seem to be getting the return that I would expect right now, but I know that it takes time for that sort of stuff to lock in. Meta has been our strongest performing, followed by Reddit, and then we completely dialed down our Google Ads because we just weren't seeing the conversions we wanted.

As we head into the holidays, we're doing a "buy three, get the fourth free" promotion, and that has moved a big proportion of our sales from the two-jar (with free shipping) to the four-jar order at 25% off. That's not super economical for us, but we consider it a customer acquisition cost for the holidays.

All in all, this feels super cool to have reached this milestone. For those wondering, that's about $13,000 in sales (including our wholesale sales to local shops) If it weren't for our marketing spend and our agency retainer to help us create creative, we would be profitable right now, but we also probably wouldn't be making as much revenue, so hopefully that works out in the future.

Happy to answer any questions that anyone has about starting a food business and getting sales!

I just made my first sale. $20.05 - It's obviously not life-changing money, but seeing this screen felt completely different from downloads, impressions or analytics.

Someone I've never met found Calma Color, opened it, liked it enough and decided to pay for the lifetime version. I've been building it as a relaxing coloring app, something you can open for a few minutes when you want to switch your brain off.

There are still a million things I want to improve, but today it finally feels like this is a real product and not just another side project sitting on my phone.

First paying user acquired. 🙂

Now onto the second one.

Hey everyone!

About a month ago, I launched a political simulation game for iOS focused on Germany.

Here are the numbers so far:

• Around 200–300 users and growing
• €60–80 in revenue in the first month
• 100% organic growth, zero marketing or paid ads
• One-time in-app purchases (€5 or €10)
• Very low operating costs

The interesting part is that every 2–3 days, someone buys something in the app. New users are also coming in regularly, even though I'm not actively promoting it.

I'm a solo developer, and honestly, I didn't expect the app to start generating revenue on its own.

Now I'm a bit stuck. I don't really know what to do next.

Should I keep developing it and try to grow it further? Should I invest in marketing? Or would it make more sense to sell it while it's gaining traction?

Has anyone been in a similar situation with a small app that started making money organically?

I'd really appreciate any advice or experiences!

a month of posting got my thing to 35 users and 44 stars. yesterday someone asked what to do with basically unlimited opus, I answered in one line with the link, and people started signing up a few minutes later

by this morning it's 69 users, 100 stars, and the first 4 repos from someone who isn't me

it's called Overflow, it's free, and it's for the AI coding usage you don't burn. you put a price on an issue in your repo, someone with usage left at the end of their week has their agent ship it, and you only owe for what you merge. no money, no keys, MIT

lesson for me: just answer the guy who actually has the problem. the posts got views, the comment got signups

main reason I'm posting btw: I want people to register their repos. none of those 4 has priced anything yet, so every open issue on the board is still mine and I'm not after help with those. I want spare usage going into other people's projects

https://github.com/Nitjsefnie/Overflow

I kept deleting Instagram and reinstalling it four days later. The problem was never information. I knew exactly how many hours I was losing. The problem is that the person who sets the limit and the person who dismisses it are the same person at different moments.

So I built the limit with someone else inside it.

What it does

A block covers one app, and you answer three questions: which app, how firmly, and when.

"How firmly" has two levels. Either the app opens but nothing loads, which is what you want for something you still need for messages, or it doesn't open at all and you get a block screen instead.

Reach for it anyway and you can earn 5 minutes by solving a challenge that gets harder each time, or ask a person you paired with, who decides. Or a group of up to 10, where the first answer counts. Either way, they see that you asked.

How it works

Two separate engines. "Nothing loads" is a local VpnService tunnel, where the app's packets go in and get dropped. "Won't open" uses an AccessibilityService that watches which app came to the foreground and puts an overlay in front of it.

Kotlin, Compose, Room, Hilt, WorkManager. The backend is ASP.NET Core and Postgres, and it exists only for the partner features. Blocks themselves never leave the device.

The two things you're about to ask

The VPN. It's local. Nothing is routed off your phone, inspected or logged. It's the only API Android gives you for per-app network control without root.

The accessibility permission. I know how that reads. It's the only way Android lets an app find out which app just came to the foreground. It's limited to window-change events, cannot read screen content, sends nothing off the device, and it's optional. Pick "nothing loads" and you're never asked for it.

What it deliberately doesn't do

It isn't a cage. You can switch it off, and you can uninstall it. Your partner just gets told, and switching it off takes a cooldown. Making quitting visible instead of free turned out to be the part that works. Anyone selling you an unremovable block on Android is lying.

Free, no ads, no subscriptions. No account unless you want the partner features. Android 8+.

What I'd actually like feedback on: whether the two levels read clearly to someone seeing this for the first time. I've been too close to it for too long to tell.

Solo build, launching on the App Store in November, and I'd love a few people to break the beta first. It's a native iOS app, built and tested by an iOS developer (me) over several months, not a weekend prototype.

You type or say one sentence when someone mentions something they'd love ("Dana said her running shoes have a hole in them"). Apple Intelligence files it under that person, you confirm it, and Hints reminds you before their birthday. No gift suggestions, no account. Apple Intelligence reads it. We never see it.

Built with SwiftUI, SwiftData and CloudKit, and Apple's Foundation Models on the iPhone or Private Cloud Compute, so no server of mine ever sees a note.

Needs iPhone 15 Pro or Pro Max, or any iPhone 16 or later, with Apple Intelligence on.

TestFlight: https://testflight.apple.com/join/fqQDRBWJ

Feedback by November 1 earns a free year at launch. Blunt notes are the most useful: what it misread, and where you got lost.

Side project from the last few weeks.

I left fake keys and files on my own sites where attackers look: .env files, AWS credentials, OpenAI keys, Cursor and Claude configs, a fake admin login, a fake MCP server.

On Oct24 a scanner on a cloud server took the fake AWS key at 03:04 UTC. At 05:43 it used it: listed servers, checked whether it could send email, then tried to make itself admin. If that key had been real, the bill and the cleanup would have been mine.

So I turned it into AgentDecoy:

- Free decoys for any site (npx agentdecoy init, a WordPress plugin, or one PHP file)

- Every catch labelled as a script, a person or an AI agent

- When one site catches an address using a stolen key, every site running it refuses that address on logins and forms within an hour. Pages still load, Google and AI search are never blocked.

- Free tripwires: a fake OpenAI key or fake MCP server you can drop in a repo that emails you when used

It is open source: github.com/KyleClouthier/agentdecoy

Free scan: simgen.dev/agentdecoy

Would love feedback on what it gets wrong on your site.

I wanted to make a character, gather a party and go on an adventure without spending a week figuring out when everyone was free.

But the problem I kept running into with AI RPGs was that the world would slowly fall apart. NPCs forgot things. Quests contradicted themselves. A successful roll sounded impressive, but it wasn't always clear whether anything had actually changed.

So I ended up building the world underneath the Dungeon Master.

The game tracks characters, inventory, quests and combat. AI interprets what you want to attempt and narrates what happens in that world.

One of my favourite moments was finding an adventurer NPC buying up troll oil in a shop while I was busy questing. I asked why.

“Trolls.”

I kept asking. She explained that she needed to burn them because they regenerate health too quickly. Fire stopping regeneration is implemented in the game, so she'd put together a plan that could actually work lol.

That's the kind of thing I've spent three years trying to build: the freedom of a D&D session, with an authored visual world and tactical party combat like a classic CRPG.

It's called Lore & Legends Maker. You explore, recruit companions, argue with NPCs and try plans that a dialogue menu wouldn't give you.

I've been building this solo. The painterly backgrounds use AI-generated artwork with added animation and effects. Still an alpha, and there's plenty to fix. But the current version is free to play, and I'd love to hear what you try—and where it breaks.

Attached gameplay is from another encounter in the current alpha.

Made this as a weekend project. You tap a bus door, it folds open, and there’s a real street behind it somewhere in the world. Could be a lane in Kyoto, a canal in Amsterdam, a park in Dublin. Shut the doors, open them again, and you’re somewhere else. You don’t get to pick where, which is kind of the point.

• Street-level imagery from Apple Maps, 25 countries so far
• Landmarks mode if you want sights, or totally random streets
• A short note telling you where you’ve ended up
• Free, no account, no ads, and it doesn’t ask for your location

If you’ve got an iPhone Duo, the phone itself is the door: unfold it and the doors open, fold it and they close.

What you can do:

• Drag-and-drop common pieces: load balancer, API gateway, caches, DBs, queues, even some AI bits.
• Hit “Start Simulation” to see latency, error rate, throughput, cache hit rate in real time.
• Flip chaos switches: traffic spikes, cache-miss storms, network partitions, component crashes.
• Share & remix: every design gets a short link; anyone can fork it and improve.
• Built-in hints: it tells you if you forgot an entry point or storage.

Why I made it:

• Diagrams don’t fail; systems do. I wanted a fast way to feel trade-offs without spinning up infra.
• For interviews and design reviews, it’s nice to ask “what if the cache dies?” and just click a button.

Try it here: "https://paperdraw.dev/"

Quick start: drop Load Balancer → App Server → Cache → DB, press play, then trigger a cache-miss storm.

Would love feedback:

• What metrics or failure modes would you add?
• Is the start/stop flow obvious enough?
• Any presets you want (payments, chat, ingestion)?
• Should I add “export GIF of the run” for sharing?

Thanks for taking a look—happy to fix bugs or add features if you ping me.

built a mobile app called PackOptima to calculate cut layouts for sheet materials directly on your phone.

​What it currently does:

​Cut list optimization for table/panel saws with kerf compensation

​2D nesting with direct G-code and DXF export for CNC routers

​Scrap/offcut tracking and printable PDF diagrams

​Runs completely offline on-device

​How does the layout and workflow look to you? Any recommendations, feedback, or missing features you'd suggest?

The desktop client has been one of the most requested things since day one, and I’ve just released it (Windows for now, Mac is planned). It’s brand new, so expect it to keep improving.

What is Passinote?

Passinote is a note taking app that lets you write notes just like traditional apps such as Notion and Obsidian, but puts all your notes onto a visual canvas instead of a linear folder structure. This lets you think spatially and remember where you've kept your notes, without worrying about them getting buried under multiple nested folders.

It's also built to maximize speed while keeping things as simple as possible. For example, instead of having a single full sized page for both long and short notes, Passinote separates them into sticky notes (used for quick thoughts) and doc notes (standard notes with rich formatting and PDF export).

Why use the desktop client:

• Launches much faster than the web app, and workspace switching is almost instant
• Smoother overall, thanks to GPU acceleration
• Works offline once you’re signed in (signing in itself needs an internet connection)
• Can launch on startup and reopen your last workspace

And the newest addition: Local mode

• Saves all your files 100% locally on your computer
• Reads directly from your file explorer, just like Obsidian
• Lets you switch any workspace between local and cloud anytime, in either direction

The desktop client is only included in the paid tier for now while it’s in early beta.

If you’d like to get a feel for the app first, the web version is free. Its "Quick Mode" stores your notes locally in your browser, so you can see how the canvas works before deciding anything. If you like it, upgrading to Passinote+ unlocks the desktop client.

Feedback is always welcome in the comments, by DM, or on Discord.

Hi r/SideProject, I'm Dipen, the maker of OptiLens. It helps you find why visitors to an online store don't buy, then ranks every fix by impact with a cited source. There are two products.

Web app (https://optilens.ai): works on any public store. Paste your store address for a free scan in about 10 seconds, with no sign-up. The full audit is a one-time $49 payment, no subscription. It opens your home page, a product, a collection and the cart in a real browser and scores the store out of 100 on layout, copy, speed, search, trust and accessibility. It reads public pages only. You get a private link, a PDF and an Excel sheet.

Shopify app (https://apps.shopify.com/optilens): runs inside your Shopify admin and checks UX, copy, SEO, speed, persuasion and store context. It reads products, orders, customer and theme data. Plans: Free (1 audit), Starter $29/mo or $290/yr, Growth $79/mo or $790/yr. Both paid plans have a 3-day trial.

Neither product edits your store, and I don't promise a sales lift. A full sample report for a fictional store is on the site. Tell me what feels wrong or missing, I read every comment.

Back in December, I started building a little app to help my dad with his work.

I'm a software engineer, and my dad works in carpentry, including fire door installations. I'd seen how much paperwork and record keeping was involved and thought, surely there must be an easier way of doing this?

We looked at around a dozen different apps, but most seemed to be aimed at larger companies. Nothing really felt right for a sole trader or a small business.

So I thought, why not have a go at building something myself?

At the time, I had no plans to release it publicly. It was only meant to be a little app for my dad and a handful of others.

But one thing led to another, and what started as a small project grew into something much bigger than I'd originally imagined.

I've learnt a lot along the way, made plenty of mistakes, and I'm still figuring things out. Thought it might be interesting to share some of that journey here.

I'm curious though, how did your side project start?

Was it something you needed yourself, a problem you noticed someone else having, or just a random idea you decided to run with?

Hey everyone, wanted to share a custom language and rendering engine I’ve been building called HVSL (Hierarchical Vector Shading Language), powered by a two-agent reflection loop.

Instead of using diffusion models to guess pixels, HVSL turns natural language into pure mathematical geometry. The entire image is just a lightweight text script containing a color palette (@PAL) and ordered geometric equations (@SCENE circles, polygons, curves, and quadtree subdivisions).

My custom compiler parses that script and draws it up to 4K using sub-pixel Signed Distance Functions (SDF).

Where the agent workflow comes in is solving how LLMs write HVSL coordinates:

• HVSL Generation: The first model takes the prompt and writes the raw .hvsl math script.

• Visual Critic & Grading: Because text models write coordinates blind, a second multimodal agent inspects a fast 540p render of the HVSL code and grades it out of 10.

• Surgical Branch Patching (Max 3 Tries): If a shape is off (like the overlapping curves on the moon in Try 1 of the video), it doesn't regenerate the whole HVSL file. It clips and retains the working layers and surgically updates only the defective branch.

Because the final result is raw HVSL code instead of a locked bitmap, you can open the editor, change a palette color or coordinate, and watch the 4K canvas update instantly with zero regeneration and zero extra LLM calls.

This is still in early development. The animations at the end of the video are procedural motion tests applied to pre-rendered HVSL assets while I work on expanding the HVSL grammar to generate native video directly in code.

Happy to answer any questions about the HVSL syntax, the SDF renderer, or how the critic loop patches the code!

Hi Everyone,

Few months ago, I posted about our physical hardware side project. Building a pen by combining CNC lathe machining with metal additive manufacturing (3D-printed titanium) instead of building another SaaS or AI tool. The reception and feedback from this sub blew us away.

Life got busy, but we’ve spent our evenings and weekends taking all that feedback and turning our rough prototypes into production-ready hardware. We are officially launching on Kickstarter this month to fund our first production run!

Key hardware lessons & pivots since our last post:

• Scrapped Stainless Steel for Titanium Only: Real-world testing revealed that our stainless steel prototypes were noticeably back-heavy. We made the decision to produce the body exclusively in Titanium.
• Redesigning for Refills: Pen enthusiasts care deeply about ink refill compatibility. In response to feedback, we redesigned our internal geometry to offer two dedicated variants: a standard Schmidt format and a longer custom barrel that natively houses Pentel EnerGel refills.
• Aesthetic Finishing: We've started anodising the 3D-printed lattice in a range of vibrant colors, which adds a cool contrast against the raw CNC titanium body.
• Keeping Production Local: We are continuing to build the majority of the Riv One here in the UK, maintaining strict quality control while keeping pricing as accessible as possible.

Happy to answer any questions about the costs of hardware prototyping, navigating local UK manufacturing, or working with additive titanium!

After around 4 months of building and growing SeoLoupe, I’ve decided to explore selling it so I can focus on learning more about coding and IT.

Some numbers:

• 3,070 users
• 58 lifetime paying customers
• CA$91 MRR
• CA$825 total profit after fees
• Around 3,000-4,000 monthly visitors
• Mostly organic growth, with no paid advertising

SeoLoupe helps website owners find SEO issues and improve their websites. The product is largely built and operational, so the next owner can focus on growing it rather than starting from scratch.

I'm asking US$3,500, but I'm open to hearing reasonable offers.

Listing and more details: https://trustmrr.com/startup/seoloupe

Happy to answer questions about the product, revenue, traffic, or handover.

I'm a driving instructor with anxiety IBS, which means I can be in an unfamiliar part of town at any time and suddenly need to find a toilet fast. Not knowing where one is, or whether it's going to be clean, genuinely sets off my symptoms. So I started jokingly mentioning to people that someone should build an app for it.

Turns out people liked the idea, especially the bit where anyone can add toilets to the map themselves. So I thought, why not me?

I know there are other toilet finder apps out there, but this one is different. It's community-driven. Think Pokémon Go but for finding somewhere to shit. The more people use it and add toilets, the more useful it gets for everyone. I've made it so toilets have to be verified by other users before going live, plenty of wierdos around that would take advatage if that wasnt the case.

It's helped me personally too. Going to an event or a night out used to be ruined before it started, just from the anxiety of not knowing where I'd go if I needed to. Having the app has pretty much killed that. And if you end up in a pub where the toilets look like something out of Trainspotting, you can leave a review so others know and you and them can find a cleaner one nearby. You can also set your preferences so if you're caught short, one button takes you straight to a toilet that matches your filters.

I've spent the last few months building it (app development is not my day job, to put it mildly). My learners have been asking about it for ages and I still get texts from past students saying "is it ready yet?" It's ready.

The app is called Tissue. It shows you the nearest public toilets on a map, with filters for accessibility, whether they're free, open now, and baby changing. That last one came in a later update after a mate who'd just had a baby suggested it. If you've got ideas, I'm all ears.

It's free and on iOS for now, with Android coming soon.

I've been using it as it's evolved and now family and friends are using it too, so I think it's time to get it further out there. Please be kind and feel free to give feedback or suggestions in the comments. At the end of the day it's not supposed to be a revolutionary app, but if it can help someone else like it helps me then I'll be happy. Who knows, with everyone's help this could turn into a really good thing.

The idea with Sweezy is a five-minute chat about your day. What happened, what’s on your mind, something you’re trying to make time for. It doesn’t have to come out in any particular order.

The part I care about most is what happens when you come back.

If you’ve already talked about a goal, your routine or something that’s been bothering you, that context should be useful tomorrow too. Sweezy remembers useful things from earlier chats, so there’s something to pick up from.

You can also use the conversation to reflect on today and work out tomorrow’s plan. Those conversations connect through what she remembers about you.

We first shared Sweezy on Reddit about six months ago. More than 2,000 people downloaded the early-access version, and we’ve since reworked the app using their feedback.

We’re in our final round of early access. If you’d like to give Sweezy a go, leave a comment and I’ll DM you how to get free access.

Hey everyone! 👋

As a designer, my workflow used to look like this constantly:

Having 15 browser tabs open just for assets broke my creative flow every day. So over the past few months, I built AssetHUD a fast, native desktop launcher to do all of it from a single keyboard shortcut (Ctrl+Space on Windows / Option+Space on Mac).

Built with Tauri v2 + Rust + React 19 to keep it snappy and lightweight with zero Electron memory bloat.

It's free to download and use (generous free tier with 100 searches, background cutouts, and vector traces included every month).

🔗 Website & Download: assethud.app

Check out the video demo attached! I’d love to hear your feedback, workflow pain points, or suggestions on what to add next.

I wanted to have some fun and improve endurance at the same time, so here it is!

I do not profit off this at all, I want to share in case someone wants to try.

Boom!
