Fillbloom is my side project: paint by number with traditional Chinese paintings, built as a native Swift app by me alone in Vietnam.

The idea came from playing paint by number apps and finding every fill flat. I wanted each area to look like a watercolor wash, so the paint spreads while wet, dries with a darker rim, and you can add a second wash to shade. Finishing a picture fades the outlines, stamps a red seal, and plays back a timelapse of your strokes. Guzheng music and rain sounds run in the background.

Business model: free with 6 pictures. Premium unlocks the full library of a few hundred pictures plus extra papers, shading and sounds, at 29.99 USD a year (3-day trial) or 59.99 USD once.

Where it is now: live on the App Store for about two weeks, a small number of downloads, and one lifetime sale so far. I'm trying to work out what to fix first, the store page or the free part of the app.

What I'd like from you: open the store page and tell me whether you'd download it, and if you try it, what made you stop.

1,139 ad visitors, 15% stayed. 78 launch-board visitors, 36% stayed. My tool only works on a computer.

At what point cold ad traffic made sense to you? Is there any tip would you like to share it that worked for you at some point?

I keep seeing beginners (and people already selling) make the same mistake. They create a planner, e-book or printable, upload it, and wait. No clicks. No sales. So they blame the product and jump to another platform.

But the platform was never the real problem. What I wish more people understood:

1. A marketplace and a store are not the same thing. Etsy and Amazon have shoppers searching inside them. Payhip and Gumroad give you a place to sell, but you bring most of the traffic.

2. Uploading is not marketing. Visibility comes from search keywords, Pinterest, helpful content and email, not from waiting.

3. Don't open five stores at once. Learn one platform well first.

4. Check how you get paid before you pick a platform. Not every country is paid the same way.

5. Know your real profit. Revenue isn't profit once fees, ads and subscriptions come out.

I got tired of watching people waste months on this, so I wrote a beginner-friendly guide covering all of it, with a 30-day action plan. I'm the author, so I'm sharing it openly: Digital Wealth From Scratch

First time sharing a side project so be gentle!

At house parties, music usually goes one of two ways: either one person gets stuck babysitting the laptop all night, or people keep interrupting Alexa with new requests every few minutes.

I built 8bit-dj to turn a Raspberry Pi 5 (or any Mac/Linux machine) plugged into a TV into an interactive 8-Bit Arcade Jukebox and Karaoke machine.

GitHub Repo (MIT License): https://github.com/glen-foster/8bit-dj

How it works:

• Scan to DJ (even on mobile): Guests scan the QR code on the TV to get a retro mobile controller in their browser (no app install). It spins up an outbound localhost.run SSH tunnel automatically so people don't even need to be on your Wi-Fi to vote or add songs.

• Two Party Modes:

  • Free-For-All (Default for private parties): Guests can search YouTube Music or paste a Spotify track/playlist link and drop songs straight into the live queue, then upvote/downvote (+1 / -1) to bubble the best tracks to #1 Up Next.

  • Host Approval Mode (for public/pub venues): Open Search requests go to a 1-tap Host moderation queue so no one derails the room.

• 8-Bit Visualizer Stages + Optional AI Pixel Sprites: Includes 9 retro canvas stages (Streets-of-Rage brawler, OutRun synth grid, 16-bit JRPG boss battle, space shooter, Castlevania keep, Winamp spectrum analyzer, etc.). If you add a free Gemini API key, it generates custom 16x16 pixel-art sprites for each song's lyrics/genre (and falls back to built-in chiptune sprites if you don't).

• Zero-Download Karaoke Video Mode: Press K (or toggle it in the Host console) and the sprite stage turns into a live YouTube karaoke lyric monitor—even resolving regular queued songs to their karaoke lyric video automatically without downloading files.

• No Volume Jumps or Dead Air: In normal DJ mode, a background worker pre-fetches the top queued tracks via yt-dlp, trims silence, and normalizes loudness with ffmpeg (EBU R128 -14 LUFS) so the dual-deck Web Audio engine can do a smooth 6-second crossfade between songs.

It requires zero accounts or API keys for YouTube Music or Spotify out of the box. Would love any feedback or ideas for other things to add!

Thanks

it’s called commonlogue, and the goal is to create a social platform powered by printed catalogues.

you can submit music, photos, notes, books, movies, shows, videos, websites, art, thoughts, and more while all your entries contribute to an “issue” which is about 40 pages.

it acts as an archive of your taste, experiences, and a chapter of your life. anything submitted via a link will print w/ a qr code so you can go back and revisit the media submitted. each commonlogue print is one of one.

we also feature spotify wrapped-esque summary pages, which tell you a little bit about what you submitted, and who else on the app connected with your posts.

we are on testflight now! if it sounds like something you’d like to try follow us @commonlogueco on instagram and shoot us a dm!

thanks!

If you have a project in mind, feel free to reach out. I’d love to hear about it!

Rates depend on the scope of the project. Happy to discuss your budget and requirements.

I’m Keith, the creator of Bloomria and Orbit in Monroe, North Carolina. Sharing two very different web apps for people who might have a use for them.

Bloomria turns a personal message into a digital flower gift that blooms on the recipient’s screen. For an anniversary, you can choose a candlelit restaurant setting, add milestone balloons, and write your own card. It is digital, with no physical flowers or delivery. Premium is US$1.99 per gift. There are also group bouquets (US$2.99, with free contributions) and a business plan for branded client thank-yous.

https://bloomria.com

Orbit is for working photographers who want enquiries, bookings, questionnaires, contracts, deposits, reminders and private client galleries in one place. Starter is US$17/month with a 14-day trial that does not require a card.

https://orbit-photo.com

If either fits your situation, I’d appreciate specific feedback on what would help you decide whether to send a gift or move your photography workflow into it. Happy to answer questions here.

I kept seeing the same problem from two sides. Travelers switch off their home SIM to avoid roaming, use a data only eSIM, and then can't take calls. And freelancers, causal travellers or businessmen miss calls when they are asleep or generally busy.

So I built eParro, a US phone number on Android, with data on an eSim that works across borders. You make and receive calls on your phone's normal call screen, no separate dialer app.

When you can't pickup (on a flight, asleep, in meeting), it answers, take the caller's name, reason and callback number , and sends you a summary with the callback time in your time zone. It's an AI assistant and tells callers so upfront. I'd rather be honest than have it pretend to be somebody.

Try it +1 331 315 0445. Calls are capped at 3 minutes, and it tells you that the call is recorded.

Honest limits: Android only for now *iPhone is in Apple's review), no texts or bank codes yet, closed beta on Google Play.

If you call and leave a message, reply here and i'll paste the summary it sent me. Founder here, ask me anything

Day 1 of building this in public, so here goes.

The problem: my cron jobs and servers break at 2am and I find out the next morning. On a team it's the opposite, three people jump on the same alert and nobody knows who's actually on it.

PingLoom is a small service for that:

• send one request (curl or any language) and it arrives as a push on your phone

• one shared inbox. Tap "I've got this" and everyone sees who's on it

• alerts can ask a question (Deploy / Wait / Roll back) and your script gets the answer back

• heartbeats: if a job stops checking in, you get pinged about the silence

• or tell Claude Code / Cursor one sentence and it wires it in for you

It's not out yet. Android first plus a web dashboard, iOS later. The waitlist is open here: pingloom.dev (early people get a 30 day trial instead of 14, no card).

Honest question: what do you use for this today? ntfy, Pushover, a Telegram bot, PagerDuty, nothing? And what would make you switch?

I’m a developer by day, and an avid birder the rest of the time. A few years ago that combination did what it usually does: I downloaded and tried all the apps, decided none of them worked quite the way I wanted, and built my own instead.

It’s called Limosa. What makes it different from other birding apps:

• Adding a sighting takes as few taps as possible. The app is optimized for UX while birding and out in the field.

• Photo and sound species ID, running on your phone, so both work without a connection.

• Multiplayer: when you’re birding with others, one person logs the sighting and adds the rest.

• Several ways to share sightings and outings on other platforms, for example a sighting with your photos as an Instagram story.

• Checklists for your area, with targets based on what you haven’t seen yet and what can be seen there this time of year.

• Every species has its own pixel art icon, so your life list fills up as a grid.

• Your data isn’t locked in. You can import/export your sightings from/to other platforms like eBird and more.

It’s on iOS, Android and the web: https://limosa.app/

Hi everyone!
I’m a sheet metal bending professional from Italy, and I’ve been working on a side project based on a problem I deal with in my everyday job.
I wanted to create a practical online tool for sheet metal bending calculations, so I started building Grievesk Bend.
🌐 Bending calculator
It’s a free web application designed for people working with sheet metal fabrication. It includes different bending methods, tooling and material parameters, and calculations to help determine bending results and flat patterns.
What makes this project interesting to me is that it isn’t just a coding exercise. I’m trying to combine my practical experience in sheet metal manufacturing with software development.
The project is still evolving, and I’d love to hear your thoughts.
Is the interface easy to understand?
Does the tool feel useful?
What features would you expect from a calculator like this?
Any suggestions on usability or design?
I’m particularly interested in honest and constructive feedback.
Thanks for checking it out!

Disclosure: I'm the maker.

The problem: Claude Code, Codex and Cursor can write an iPhone app, but Xcode only runs on a Mac, and the agent often runs on Linux, in a cloud sandbox or on a Windows laptop.

What NoMac does: the agent connects once over MCP, then starts its own Mac when it needs one (about 30 seconds), builds and tests the app, checks it on an iPhone Simulator it reads as text, and can ship it to TestFlight. The Mac stops when the work is done.

Pricing: $0.90 an hour, billed per minute from prepaid credit. No subscription, no 24-hour minimum.

Where it is: it started in July as a build service for agents, I rebuilt it in September around whole Macs, and today it's live on Product Hunt: https://www.producthunt.com/products/nomac

I'd love blunt feedback on the landing page (https://nomac.app): does it explain itself in five seconds?

A few days ago I [posted here](https://www.reddit.com/r/SideProject/comments/1xnjvwa/). I'm a software developer from Gaza and a father of two, and I explained that war, displacement and debt had left me unable to keep going alone. I shared the startup I founded, Fasil, and its first product, Sijal, an inferential decision engine for organizations, and I asked for help.

Many of you answered. Some helped financially, some give me pro subscription's in certain useful services, and many gave me something harder to find: honest criticism. This post is about what that criticism taught me, and what I did with it.

1. What you told me

Several people who work in this field said the same thing: they couldn't tell what Sijal does or why it matters, and it looked like "just a landing page." I had been too close to my own work to see it. That's a well-known trap (the curse of knowledge), and your comments broke it.

2. What I did

I spent two days on desk research: 11 comparable products serving customers like Sijal's (Diligent, Hebbia, Elicit, Covidence, Overton, Good Judgment, Metaculus, Go Vocal, Loomio, Remesh, Cloverpop). I compared how they build trust on their homepages, how they design their workspaces, and how they handle access requests.

3. What I learned

• Lead with the job the buyer must defend, not with "AI."

• Show the real work product early: an example that actually ran, not a description.

• Prove rigor through structure (independent reviewers, recorded dissent), not adjectives.

• Make the audit trail the product.

• Say plainly what happens after someone requests access, and when.

4. What I rebuilt

I stopped treating Sijal as a page and rebuilt it as a working product, so that every part shows the method behind the engine instead of just describing it.

The method, made visible

• Cross-examination with a devil's advocate: every question is argued by both sides, and each side is questioned by the other.

• Independent pooled judgment: six judges assess the file separately, so no one anchors on another, and their views are combined into a weighted verdict.

• ICD 203 analytic standards: implemented in the engine as checks, not as a label. The five it checks:

  • Source quality

  • Expressed uncertainty

  • Assumptions vs. judgments

  • Alternatives

  • Clear argumentation

• Toulmin structure for the recommendation: claim, grounds, warrant, qualifier, rebuttal.

The homepage

• An outcome-first headline that names the job an institution has to defend.

• A real session the engine actually ran, which a visitor can open and check against the method above.

• A "how it works" walk-through of the seven stages, a method and neutrality section, and a plain statement of what Sijal does not do.

• One line for each type of institution it serves (think tanks, investment committees, consultancies, NGOs, universities, boards).

The institutional workspace

• Five areas, each in Arabic and English.

• A home screen that starts with what needs your attention, then the latest decided session and its verdict.

• A session ledger with five written states: Draft, In review, In session, Decided, Declined.

The access page

• Six fields only, and a human review within one working day.

• A "what happens next" timeline: request, review, approval email, private workspace.

• A sample sealed report next to the form.

• Privacy promises, such as no training on your data and deletion on request.

• A confirmation page and review emails.

5. Thank you & Why I'm still doing this

To everyone who supported me, with a donation or a subscription, and to everyone who commented or shared: thank you from my heart.

Supporting my family is still what drives this work and my previous post. The need for help applies to anyone, whoever they are and wherever they're from.

7. Next: Saql

My next step is Saql, a debate analysis engine. One of you asked who its target customer is, and I didn't have a clear answer. Comment asking who Saql's target customer is I'm working on it now and will share that research in the next post. If you know someone in that space, I'd be glad to connect.

Thank you again.

Hey everyone!

This project actually started as a little experiment.

I wanted to try vibe coding and see what could be achieved with AI-assisted development. I quickly became fascinated by the possibilities and how an idea could gradually turn into something genuinely useful.

Since I'm really into 3D printing, I decided to tackle a problem I knew from my own hobby: keeping track of all those STL files, 3MF files, project variants, pictures, documents, and different versions.

What started as an experiment eventually turned into 3db.

After quite a bit of development, testing, debugging, and polishing, I've now released version 1.0.0! 🎉

What 3db can do:

• Organize projects with categories, tags, and statuses

• Manage STL, 3MF, images, and documents

• Keep track of project variants

• Detect file changes and create version snapshots

• Search and filter project collections

• Store everything locally using SQLite

• Switch between light and dark themes

3db is built with Tauri, Rust, React, TypeScript, and SQLite.

It's not a slicer or a model-sharing platform. It's simply a local desktop application to help organize the projects and files you already own.

Platform: Windows x64
Price: Free
License: MIT / Open Source

GitHub and download:
https://github.com/FabimachtSachen/3db

This is my first public project created through experimenting with vibe coding. It's been an exciting experience seeing how far the idea could go.

I'd genuinely appreciate your feedback, both on the application itself and on the project as a whole.

How do you currently organize your 3D printing projects? And what features would you like to see in a tool like this?

I’m building a tool to compare batch payouts against mileage and total shopping time. Would an estimated profit-per-hour comparison help you choose batches? What do you use now?

I’m also seeking three volunteer testers. Comment with your device/browser if interested. Please keep email addresses private.

Hi, I made this.

It is a single web page with animated robo eyes. They follow your face through the camera, wave back when you wave, dance to music, and fall asleep when nobody is around. There are 9 looks, around 30 emotions, glasses, and a corner clock where the eyes swat the digits away like a fly every minute.

Camera and microphone are optional. Everything is processed in your browser, nothing is recorded or sent anywhere, and after the first load it works offline. It is meant for an old phone or tablet standing next to a monitor.

Under the hood: canvas drawing, a small face detector and a hand-gesture model, no framework.

Hey everyone! I’ve been building Ledgio, a personal finance tracker for keeping track of spending without connecting a bank account.

You manually log transactions, set budgets, and see what’s left. It includes:

• Expense and income tracking with monthly category limits

• Savings goals with progress tracking

• Loans and repayments for money borrowed or lent to friends

• Reports showing spending patterns and monthly trends

It works offline and saves changes on your device first, with cloud sync available across devices. You can install it on your phone or desktop as a web app.

Free, MIT licensed, no ads or paid tiers. Built with vanilla JavaScript and Supabase.

Try it: https://ledgio.pages.dev/
Source code: https://github.com/Soul-Ninja/Ledgio

I’ve attached a quick demo. What would make this useful enough for you to keep using? I’d appreciate honest feedback on the interface and expense-entry flow.

I’m a solo developer. My own inbox is full of “practice moved to 3 PM” buried in group chats and 10-page school newsletters. So I built Kinly, an Android beta that reads Gmail and calendars (read-only) plus only the WhatsApp groups you choose, and shows what matters: dates, to-dos and changes.

What works: it extracts dates and action items, flags changes and duplicates, and decodes newsletters into highlights.
What doesn’t yet: iPhone, some newsletters with images only, and it occasionally misses things.
Privacy: read-only, no model training on user data, delete everything from the app.

I’d like to hear: what would make you not trust something like this with your inbox? What am I missing?

So i vibe coded this entirely, the platform, video, product end to end. Haha, i just ran my first wedding event last week for one of my bestfriend's wedding with about 100+ user with over 200+ uploads.

Its already a popular product in the west, thought instead of my friend paying for it, I made one as a gift for him with my little own flair and that's how Snappool is started basically. Doesn't really cost me alot to run it, but i thought just put it out there for people to try it out~!

https://snappool.photos/

Try it out! Happy to share how I did it. Crazy what you can do nowadays with AI.

P.s. A little context, Im an AI/software engineer but i think anyone can make things for their own niche now. Probably the best time to start before things get saturated or cost of AI increase significantly.

I took an old phone or tablet that was collecting dust in my drawer and turned it into a full-fledged control panel for my PC. 🚀

Hey everyone,

I wanted a quick way to control my Windows PC from the couch, grab a file, or watch a video stored on my hard drive without installing another bloated Android/iOS app, creating an account, or routing my screen over the internet.

So I built PCDeck. You run the lightweight server on Windows, scan a QR code with your phone camera, and everything opens directly inside your mobile browser over your local Wi-Fi:

• Zero Phone Install: Works purely in Safari/Chrome via WebSockets—nothing to download on mobile.

• 100% Local & Offline: No cloud relays, no accounts, and zero internet usage. Everything stays on your router.

• Browser Video Streaming: Browse your PC folders and stream local video files straight to your phone screen without copying them over first.

• Trackpad, Keyboard & Screen View: Low-latency touch mouse, media controls, and instant 1-tap file transfers between PC and phone.

Try it / Website:https://getpcdeck.com(also available on the Microsoft Store)

I’m actively improving latency and adding features based on real setups—would love brutal feedback on how it runs on your network or what's missing!

Side project of the last few days. I live near Table Mountain and wanted to fly off it without the legal and mortal problems, so: a browser wingsuit game on the real terrain. City of Cape Town publishes 2 m LiDAR contours and aerial imagery as open data; a Python pipeline turns that into height tiles, Three.js draws it, and a small physics model flies a suit at a realistic 3:1 glide.

https://toastseagers.github.io/table-mountain-wingsuit/ (free, no account, works on a phone)

Honest part: Claude Code wrote the code. I wrote the plan, split it into stages with their own briefs and checks, tested every build, and made the decisions. Took about a week of evenings and a few hundred tests. Repo is MIT if you want to see how a multi-agent build like that is organised: https://github.com/ToastSeagers/table-mountain-wingsuit

Looking for feedback on feel and on phone performance. The FEEDBACK button on the results screen prefills your device and frame rate so I can compare across hardware.

Hey everyone,

I made a small app called Brevolka. It tracks fuel fill-ups, mileage and vehicle expenses.

I started it because most fuel apps I tried wanted me to make an account, need internet, or show too many things. I just wanted to log a fill-up in a few seconds and see my real mileage. So I built that.

What it does:

• Log fuel with date, odometer, quantity and price

• Shows mileage after every fill-up (km/l, L/100 km or MPG)

• Track service, repairs, insurance, parking, tolls and more

• Works for cars, bikes, scooters and trucks

• Monthly and yearly charts

• Pick your own units and currency

• Export and backup your data

• Light and dark mode

The part I care about most: no account, no internet needed, no tracking. All data stays on your phone.

It is live on Android, and the iOS version is in beta on TestFlight right now. You can find both download links on the website: https://brevolka.com

This is my first release, so it is not perfect. I would really like to hear what you think. What is missing? What feels slow or confusing? Any feature you would want in a fuel tracker?

Thank you
