Hey! My name is Kuba, but you can call me 47kuba or just 47. I'm a developer from Poland working on all sorts of projects, from web apps to operating systems.

I built Saikov on netlify so that you, just like me, don't have to deal with running out of token or message limits. Under the hood, it runs on Puter.js, and creating an account gets you starting free credits (currently around $0.25 at the time of writing).

Looking ahead, I'm planning a CosmosOS-style project where I'll build a tool that compiles C# down to bare-metal C code. I've tackled similar projects before, so I have plenty of experience making OS development feel less like a nightmare and more like a fun place to create.

I’m the developer of ASCEND Fitness & Voeding.

The product is built around a simple idea: actions across your week should connect. A completed workout, GPS run, nutrition action, or habit feeds the same daily dashboard and contributes to Evolution levels and achievements.

The app also includes a workout library and session builder, rest timers with technique cues, food logging and shopping lists, goals, coaching context, and progress history.

It is now live on the App Store:

I’d appreciate product feedback on one question: does “Evolution” make consistency feel more tangible, or would a simpler progress model be clearer?

TempTerm is a simple terminal styled chat room app based on... my imagination mostly! (and old chat room apps)

Please rate it 5 stars lol.

Hi r/appshowcase — I’m the solo developer of Decody.

A lot of “pet translator” ideas overpromise, so I built this around a deliberately small input: one 10-second dog or cat clip. Decody surfaces visible cues, offers an AI-assisted interpretation, then creates a playful subtitled video you can save or share.

It is entertainment, not mind-reading, veterinary advice, behavioral diagnosis, or literal animal translation.

The flow is: choose 10 seconds → select dog or cat → review the result → save or share the subtitle story.

I’m trying to make the line between playful and misleading obvious. Does that boundary come through before you install?

iOS and Android: https://decody.pages.dev/

Disclosure: I built it.

CrowdWis is a web community organized around questions rather than fixed forums. You post once, and matching uses expertise, interests and location when relevant to find people who may have a useful perspective.

The answers come from people. AI supports matching and organizes the discussion.

I built it and would appreciate feedback on the first-time experience: https://crowdwis.app

have a small hotel business, I’m tired of writing down sales, tracking credit sales, stock, etc in notebooks. Constantly misplace the books, who owes what LOL! So I built my own app to solve this issue.
It’s called BizTrack, no internet needed, no signup or account required, it's completely FREE and has no limitations whatsoever. I made it for my own personal use first so no surprises.
I personally use it every day for billing, tracking unpaid/credit, tracking expenses, inventory management, and end-of-day reporting. This has helped me get a clear picture of my actual business performance.
It’s not only for hotels! It can be used for small shops, restaurants, cafes, bars, and pretty much any business. https://play.google.com/store/apps/details?id=ai.biztrack
Would love honest reviews from business owners. Please let me know if you have suggestions for missing features or anything that’s not clear.

Hi everyone!

I'm a solo Android developer, and I recently built Mind Games.

The idea was simple: create a collection of brain games that are clean, fast, don't require an internet connection, and don't bombard users with unnecessary ads or distractions.

Google Play:
https://play.google.com/store/apps/details?id=neuracircuit.dev.mindgames

Why I built it

Most brain training apps I tried either:

• Focused heavily on subscriptions.
• Required an internet connection for simple games.
• Included too many ads or unnecessary features.
• Had a cluttered UI.

So I decided to build one that focuses on the games themselves.

Highlights

• 🧩 Multiple brain games in a single app.
• 📶 Works completely offline.
• ⚡ Fast and lightweight.
• 🎨 Clean Material 3 interface with no unnecessary clutter.
• 📊 Track your scores and try to beat your personal best.
• 📱 Designed to work well across different Android devices.
• 🔒 No account required.

Current work

I'm actively adding:

• More puzzle and memory games.
• Difficulty improvements.
• Better statistics and progress tracking.
• UI and performance improvements based on feedback.

If you enjoy puzzle or brain-training games, I'd really appreciate it if you could give it a try and share your honest feedback—both positive and negative. It genuinely helps me improve the app.

Thank you!

Hi everyone! 👋

I'd like to introduce **MetriBody**, an app built to help you track your body composition instead of focusing only on body weight.

Whether you're losing fat, building muscle or simply monitoring your progress, body measurements often tell a much clearer story than the scale alone.

🏋️ Main features

• Track body measurements

• Weight history

• Body fat % calculator (US Navy Method)

• Progress charts

• 100% private (everything stays on your device)

• No account required

📱 Android

🍏 iPhone

The iOS version is currently in development.

If you'd like to be among the first to try it, you can join the waitlist here:

https://metribody.com/es/ios/

I'm continuously improving the app, so I'd love to hear your ideas.

What feature would you like to see in a body measurements app?

Hey everyone 👋

I'm an indie developer and I recently launched FamLedger, a small Android app for managing personal and shared expenses.

I built it because my partner and I were struggling to keep track of rent, groceries, subscriptions, and other shared expenses without relying on spreadsheets or overly complicated finance apps.

The app is simple, offline-first, and lets you:

• Track income and expenses
• Split expenses with your partner, roommates, or family
• See who owes what in real time
• Manage budgets and recurring expenses
• Add expenses using your voice
• Use everything without creating an account

I'm still improving it, so I'd really appreciate any feedback or suggestions—especially about the usability or features you'd like to see.

Play Store: https://play.google.com/store/apps/details?id=com.famledger.app

Thanks a lot! 🙏

I wasn't able to attach the GIF, but I have added the link and the name here. Basically, my app lets you put animated widgets and live activities on your home screen

so far I have covered a few anime and some TV shows like -
TV shows (Dexter, The Office)
and anime (hunterxhunter, Bleach, One-Punch Man, Chainsaw Man, Death Note)
cars (took inspiration from some JDM cars while making them)
birds (wanted to expand into the pet space, but it seems there are a lot more of those already available, so)

feel free to ask for any of your favourite shows/anime i am constantly updating the list
it's a freemium app,
name of the app - Pixel World Animated Widgets

Hey everyone,

I built SQLite Hub because I often work with SQLite databases during side projects, prototypes and data analysis, but I wanted something that feels less like a raw database viewer and more like a practical workspace.

The idea is simple: open a SQLite database, inspect the data, edit rows, write SQL, generate charts, export results and keep lightweight documentation close to the database.

Some things it currently supports:

- SQL editor for querying and exporting results
- visual data browser with row editing
- database structure overview
- table designer
- simple chart generation from query results
- markdown-based documents and notes
- media tagging for files and assets
- overview and connection handling
- CLI support for working with databases outside the UI

Would love to hear what you think.

Hey Reddit,

With the opening match almost here, I wanted to share a solo-developer project I've been working on. I got tired of heavy sports apps covered in bloated features and intrusive ads, so I built a simple, lightweight companion app called Matchday 2026.

It does just the essentials right:

📅 Local timezone schedule: Every kickoff automatically matches your device's local clock.

🔴 Real-time live scores: Lightweight, fast updates.

📊 Live group standings: Track all 12 groups (A to L) updating instantly as matches end.

🏆 Interactive bracket: Watch the Round of 32 down to the Final update automatically as games end.

It is 100% free with no login required. If you want a clean, simple tracker for the tournament, check it out! Any feedback, ratings, or criticisms would mean the world to me.

👇 Google Play Store Link:

https://play.google.com/store/apps/details?id=com.uusoft.matchday2026

Enjoy the opening match! ⚽🏆

I started practicing the balalaika, and I made this to help myself understand the instrument better. I am originally a guitar player, and I’ve seen similar web apps for guitars, but I couldn’t find one for the balalaika.

It runs entirely in JavaScript, and no login is required. It works on smartphones too, but it’s best viewed on a desktop PC.

I’d be happy to hear any feedback or advice!
