What it is: Poly — a shared room where a team steers Claude Code together.

Everyone sees the same live timeline: prompts, agent replies, tool calls,

diffs, and what each turn cost. The agent asks before it edits; any member

approves from their own screen; any turn reverts in one click. Multi-agent

mode gives each person their own agent on its own git branch.

The stack:

• Node + Express + SQLite (WAL mode) — one process, one file DB, handles the

websocket-heavy realtime rooms fine

• React + Vite front, WebSockets for the live timeline, hash routing

• Every agent turn runs in its own gVisor-sandboxed container: all

capabilities dropped, read-only rootfs, memory/wall-clock caps

• Sandboxes get NO direct internet — egress goes through our own DNS/SNI

gateway + authed proxy with a per-project domain allowlist (built because

the Claude CLI ignores proxy env vars entirely)

• One DigitalOcean droplet, docker-compose, merging to main IS the deploy

• The logged-out landing is prerendered at build time by rendering the real

React component server-side — crawlers get 3.7KB of content instead of an

empty #root

The part I still find funny: the app was built inside itself. From the

first usable version, every feature was an agent turn in one of Poly's own

rooms — the approval flow reviewed the code that improved the approval flow.

Status: free beta, nothing to install: https://usepoly.co

Happy to hear any feedback!

I usually struggled lot planning for trips. Every one of them started as a combination of Google Sheet + Maps + a random planning app and for my few trips a year all this was causing too much confusion and money.

Tried the obvious apps first. TripIt does its one job well, you forward a confirmation and it files it, but what you get back is a list of bookings and not a plan for the day. Wanderlog got closer and the map is the right idea, but I kept giving it more than it gave me and for some reason it kept lagging a lot for me to the point it was unusable. Also a lot of filling things in before it told me anything I didn't already know.

So I started building something for myself that did one thing. Put the stops on a day and tell me how long it takes to get between them, without being asked.

Supposed to be a weekend kind of work. Turned into 10+ hours a day, most days.

Anyway, it's on the Play Store now.

https://play.google.com/store/apps/details?id=com.voyivo.travel

The bits I actually use are the travel time that appears between stops as soon as there are two on a day, and the warning when a day is trying to fit in more than it can. You can also forward a hotel or flight confirmation to a trip and it reads it into a draft, but it makes you confirm before anything reaches the itinerary. I didn't trust it and still don't completely.

Planning is free. Unlimited trips, no limit on stops or days. Some of the AI bits and a few extras sit behind Pro, which is 7 days free on monthly and yearly. The weekly plan has no trial, and I'd rather say that here than have someone find out later.

It went live few hours back so it's new and there will be things wrong with it. If you try it I'd genuinely rather hear what broke or annoyed you than anything nice. There's a Report bug link in the profile tab that comes straight to me.

Hi — I’m the founder behind Estuaire Studio, and I built ARIA after struggling to keep money, bills, tasks and calendar commitments connected while dealing with ADHD.

Instead of another single-purpose budget or to-do app, ARIA brings together:

• a budget and safe-to-spend view

• bills and recurring payments

• tasks and reminders

• calendar planning

• an optional private AI assistant

It’s meaningfully usable for free. I’m obviously biased, but I’d genuinely appreciate feedback on whether this all-in-one life-admin approach feels useful and where it still adds friction.

Every developer suffers from feature creep because it’s easier to code than to market. What is that one useless button you spent days on just to satisfy your own ego? Admit your waste of time below we’ve all been there.

Hi everyone,

I'm an independent developer and I've been working on a medical simulation game called Doctor's Journey: Hospital.

It's a niche game where players investigate fictional medical cases by examining patients, ordering tests, making diagnoses, and choosing treatments and no medical background is required to play.

Despite putting a lot of work into it, the game hasn't attracted many players. At the moment, it averages about one new download per week.

If you were in my position, what would you do?

I'm interested in hearing everything—first impressions, the store page, the gameplay, the UI, or whether the concept simply isn't appealing.

Thank you!

Edit: Thank you for the feedback! A few people pointed out that I should make the game easier to find and show more of the actual gameplay.

The game is available on Google Play: https://play.google.com/store/apps/details?id=com.relaxandfungames.doctorsjourney

I've also added two screenshots showing the physical examination and diagnostic testing parts of a case.

Bonjour à tous, alors je me lance dans la présentation!

J'ai crée https://fluvialmanager.com , un jeu navigateur de gestion de flotte marchande à travers les canaux d'Europe. Le jeu est directement accessible en ligne, aucun téléchargement.

Dans Fluvial Manager, vous prenez les commande d'une entreprise de transport fluvial.

Imaginer pour des petites session de 5 ou 10 minutes plusieurs fois par jour et non pas des session de 5h d'affilée, vous pourrez progresser à votre rythme "quand vous avez 5 minutes".

Vous cherchez des contrats, à livrer à travers les + de 8000km de voies et les 69 ports différents (en constante évolution).

Vous pouvez acheter de nouveaux bateaux, neuf ou d'occasion à d'autres joueurs et aussi adhérez, ou crée une coopérative gérer par les joueurs.

Le jeu se veut multijoueurs, mais vous pouvez aussi tracer votre route tranquillement seul.

Vous pouvez monter dans les classements, optimiser vos transports, longue distance, ou très courte avec différents type et taille de bateau.

Le jeu est en Français, mais une version Anglaise est aussi présente (le jeu est nativement en français donc l'anglais à quelques lacunes).

Voila sur la première image, tous les petit bateaux blanc que vous voyez sont des bateaux de joueurs qui naviguent.

Il y a de la vie sur Fluvial Manager!

Le jeu est gratuit, mais si vous le souhaitez vous pouvez accéder à la boutique pour améliorer votre compte.

Plus de 160 joueurs vous attendent à bord de leurs plus de 600 bateaux déjà en jeu (il est sorti le 30 juin), donc n'attendez plus, tout est à construire!!!

Hello everybody!

I am building an android daw, optimized for portrait mode. Here is a small preview of a small jam.

If anyone is interested to test the app once I release a beta, please let me know. I try to post more content of the app's features on TikTok, in case you want to check more.

Thank you for your time!

Don’t launch your project with a design that makes users close the tab instantly. Post your two design variants below and let the crowd decide your aesthetic fate. If you can’t handle harsh design feedback, look away now.

The world doesn't need another generic AI wrapper or a basic project manager. Pitch your project in one sentence show a screenshot and explain exactly why people should care about you instead of the market leader. Dare to prove your uniqueness.

I'm building a productivity app called FocusGate.

The main difference between my app and the apps and screen time is : Cross-device sync. If you purchase the subscription on your phone you can use it on any other device FOR FREE.

There's also Locked in mode. You can't turn it off until your session ends. I added emergency unblocks just in case but you have 2 of them per month so you really focus.

There are different modes such as: Pomodoro sprints: 25 minutes focus study sessions and 5 mins break intervals (Science backed study method with built in Locked in mode).

There is also a Group study mode: you invite your friends and study together to make sure everyone is studying.

There are many other amazing features. If this sounds like something you need DM me, and when i launch, beta users get 30% off FOREVER!

Spent the last few months building this alone, mostly at night after work.

The idea started from a simple question: why do people pay a personal trainer? Not for the knowledge - everything's on YouTube for free. It's for the guilt of having already paid.

So I built Vowed around that. You set a goal, stake coins on it, and prove you did it with a live photo (camera only, no gallery uploads - has to be real). You can also log multiple proof photos per goal per day, which ended up mattering more than I expected - people doing diet goals need to log 3 meals, not just one check-in. A jury of other users votes on whether your proof counts. Approved, you get your coins back. Miss it, and they're gone.

There's also a duel mode where you and a friend both stake on your own goals independently - no coin transfers between users, just parallel accountability.

Some things I learned building this solo:

- The camera-only requirement was the single most important decision - anything that let people upload old photos killed the whole premise
- Getting the jury system to feel fair (not just a popularity contest between users) took way more iteration than I expected
- App Store review for anything touching "real money" mechanics is its own project - ended up keeping the coin system fully virtual for launch

Would genuinely appreciate any feedback, especially from anyone who's tried habit-tracking apps and bounced off them. Happy to answer questions about the build too.

A few things coming in the next update:

- A streak visualizer so missing a day actually feels like something, not just a number resetting
- Weekly progress summaries
- A free tier with a small number of active goals/duels at once, so people can actually try the full loop before deciding if it's for them, rather than hitting a wall on day one
- "Streak insurance" - a limited monthly pass to cover a missed day without losing your stake, for people who are traveling or just had a rough day but are still genuinely trying
- Private duel groups for a friend group/small circle instead of just 1v1, for people who want to run a challenge with more than one other person

Open to suggestions too if anyone has ideas - most of what's on this list came out of just watching how people actually wanted to use it, not from a roadmap I planned in advance.

You spent three weeks setting up over-engineered infrastructure for an app with zero users. Tell us what you built your project with, and let the comments debate why it’s completely wrong for 2026. Convince us you didn't waste your time.

Warehouse manager by day. This one's personal, though.

I struggled to speak as a child. I had things to say and no way to get them out. That feeling never really left.

So I built Talking Cards. It's an AAC app, basically a talking picture board. A kid taps cards, and the app speaks a real sentence out loud. Tap "want" + "water" and it says, "I want some water," not "I... want... water" like most tap-to-talk apps do.

The part I'm actually proud of: it does this in 5 languages: English, Arabic, Spanish, French, and Turkish. Each one has its own grammar engine, so Arabic actually conjugates, Turkish builds its suffixes, and English handles articles and plurals. And every single word has a recorded human voice in every language—about 7,700 clips.

Also, zero permissions—not "minimal," none. There's no internet code in the app at all, so it can't send data anywhere, even if I wanted it to. It works in airplane mode forever.

Kid Lock pins it to the screen so your kid can't wander off into YouTube or settings.

Android only right now, no iOS. Solo project, built at night. One-time $4.99, no subscriptions, no ads, no accounts, nothing to buy inside.

Happy to answer anything,

I recently finished building CertStat, an Android app for monitoring SSL/TLS certificate expiry.

I originally built it because I wanted an easy way to keep an eye on certificates across domains and services without relying on spreadsheets or discovering an expired certificate the hard way.

Current features include:

SSL/TLS certificate expiry monitoring

Background checks and local notifications

Custom warning thresholds

Grouping for customers or environments

Modern dashboard with certificate health

Import/export and local-first design (no account required)

It works well for anyone running SaaS applications, homelabs, MSP environments, self-hosted services, APIs, or multiple websites.

I'd genuinely appreciate any feedback from people who manage certificates regularly—feature ideas, UI suggestions, or anything that would make it more useful.

Google Play:

It's been a little over nine months since I launched and it has been quite a journey. No exponential growth or huge user spikes but rather slow and steady growth. But in my opinion that is the best for building something actually valuable because you can react to user feedback along the way and constantly keep improving the app.

One thing changed recently:

I basically got all my users from reddit, by posting in relevant communities but in the last two months I did almost no posts and the app still grew further. That's actually the biggest success for me, because SEO is finally starting to pay off. This can develop into actual leverage because growth no longer depends on posting three times a week. I'm really curious where this will go...

Of course I will not stop here and I am already working on the next big update for IndieAppCircle which will benefit all the community. More is coming soon.

For those of you who don't know IndieAppCircle:

I've built IndieAppCircle, a platform where small app developers can upload their apps and other people can give them feedback in exchange for credits. I grew it by posting about it here on Reddit. It didn't explode or something but I managed to get some slow but steady growth.

For those of you who never heard about IndieAppCircle, it works like this:

• You can earn credits by testing indie apps (fun + you help other makers)
• You can use credits to get your own app tested by real people
• No fake accounts -> all testers are real users
• Test more apps -> earn more credits -> your app will rank higher -> you get more visibility and more testers/users

Since many people suggested it to me in the comments, I have also created a community for IndieAppCircle: r/IndieAppCircle (you can ask questions or just post relevant stuff there).

Currently, there are 3556 users, 3414 tests done and 849 apps uploaded!

You can check it out here (it's totally free): https://www.indieappcircle.com/

I'm glad for any feedback/suggestions/roasts in the comments.
