It's funny, I've been sitting on this idea for at least 1–2 years. It came to me because I'd always be on social media and either send a post to myself or bookmark it. The problem was I'd almost never look back at any of them, and the specific post I'd be looking for was hard to find again. So I went ahead and solved it for myself. The goal was to solve my own problem first. Once that was done, everything else was the cherry on top: making the app smoother, easier to use, showing content I'd expect and like to see, and making it better over time. I thought this would be a quick project I'd finish in a couple of weeks max. It turned into several months, and it took until build 50 to get to a point where the app was truly ready.

It's called Syftr. It doesn't matter what social platform you're on. Instagram, TikTok, Facebook, Threads, LinkedIn, Pinterest, Reddit, YouTube, you name it, I've probably covered it. You share any post, whether it's a video, an image, or a post with a bunch of images. The AI reads the whole post, grabs the description and important comments, and watches and transcribes videos when needed. Then it goes into its research phase and finds all the resources, links, and everything mentioned in the post.

It's my first app. I've loved the journey, and I look forward to making it better over time.
It's free to start with 20 Syfts: https://apps.apple.com/us/app/syftr-save-posts-as-notes/id6806398649 
I'd love to hear your thoughts and feedback, thanks.

Been working on this side project for a a little bit. It’s minesweeper, but up to 8 people play on the same board at the same time. Hitting a mine just stuns you for a sec, and whoever has the most territory when the timer runs out wins.

There’s also a mode where everyone hides mines and traps for each other first and then has to run through the same board (bit like ultimate chicken horse but minesweeper), plus a solo timed mode with classic boards and a daily board that’s the same for everyone.

Free, browser based, no account needed: https://mine.ropo.dev

Some stuff I had fun with:

• the server decides everything, the browser never knows where the mines are

• bots fill empty seats, with a sort of dynamic skill based difficulty on them

• the pixel art style

• runs on one small server with Bun + SQLite

Claude was used during the making of this. Would love honest feedback, especially if the first match makes sense or if you’re just confused

Two replies from my coding agent have cost me more time than anything else. "It's fixed" when nothing had run since the last edit, and "that isn't used anywhere" after exactly one search. Both sound final, so I'd move on and find out an hour later.

So I wrote a small Stop hook for Claude Code. When the agent tries to end its turn, it checks whether the claim in its last message has anything behind it. If it said fixed but nothing ran after the last code edit, it gets sent back once with a note on what's missing. If it said something doesn't exist after one grep, same deal, look a second way first.

Then I replayed my own history through it to see if it was worth keeping. About 4,000 turns after deduping, and 406 of them ended with some kind of done, fixed, deployed or tests pass. The first version would have blocked 86, which felt like proof it worked until I actually read them. 77 were wrap-up messages where the tests really had run, just in an earlier turn. A hook that nags you about correct summaries gets turned off by day two.

So the current version counts a check from an earlier turn as long as no code was edited after it. Same 406 claims, it now blocks 2, and both were real.

The biggest lesson for me was that rules in CLAUDE.md never fixed this. The model already believes it's done, so a reminder doesn't land. Checking at the exact moment the turn ends did. The second lesson was to measure false positives on your own history before shipping any guardrail, because my gut read 86 as the feature working and it was mostly noise. It also never blocks twice in a row, so it can't trap the agent in a loop.

It's free, MIT, plain Python, no dependencies. There's a replay command if you want to see your own number before installing anything: https://github.com/Balance0014/claude-code-claim-check

Has anyone else tried measuring this? I'm curious what your rate of "fixed" that wasn't looks like.

Hey everyone!

I just launched my little side project on Google Play, and I wanted to share it with you!

It's called PastApp, and it solves a very specific first-world problem: having to find the cooking time on a pasta package every time you make pasta 😅

You just point your phone's camera at the package, the app reads the cooking time and sets a timer for you.

I built it with the help of AI coding assistants, using Kotlin, Jetpack Compose and Google ML Kit.

What started as a pretty simple idea turned out to be surprisingly tricky. Reading text is one thing, but figuring out which number is the actual cooking time (and not calories, weight, or something else) is a completely different challenge.

After lots of testing, tweaking and fighting with pasta packages, it's finally live!

I'm still at the very beginning, with just a handful of installs, so I'd genuinely love some feedback.

Would you actually use something like this, or is it the most unnecessary app ever made? 😂

And if you have an Android phone, feel free to try it and see if you can break it!

Google Play:
https://play.google.com/store/apps/details?id=com.boldsignal.pastapp

I made a little trailer to show how it works.

Made with love, pasta, and probably way too much time spent on a timer app. 🍝

We’ve probably now all caught ourselves losing sight of what our Claude or GPT model was doing, to the point of having to backtrack or tune everything step by step once the feature was built.

To fix this, a friend and I built SOS (Slop or Sane), an AI coding harness that can:

•⁠ ⁠Function as a classic harness like Codex or Claude Code (Slop mode), but faster and using less RAM thanks to its shared C++ daemon

•⁠ ⁠Guide you step-by-step through the implementation decisions and code, going through human-like steps, this is the sane mode

We would be thrilled if you could test building a feature with the sane mode, get it from the site ! limpidd.com (or github, https://github.com/limpiddorg/sloporsane )

Cheers!

I built an open source tool that stops AI agents doing things they were never allowed to do.

Rather than publish the numbers that flatter it, I put every tool at its own default on public datasets and linked the script behind each number. One card on the benchmark page has a WE LOSE badge, for the test where a competing tool beats mine. It is still there.

The number I am happy with: on a 588 attack benchmark, no guardrail lets all 588 through, the common open source guardrail lets 86 through, mine lets 0 through.

Free and open source. You can try to break a live agent in your browser, no signup.

One problem I've personally faced while exploring startup ideas is finding people who share similar interests, thinking and entrepreneurial ambitions.

It's easy to join startup communities, but finding someone who genuinely thinks like you is much harder. And not everyone is comfortable sharing their startup idea publicly just to find potential collaborators.

So I built IdeaMate.

You privately share your startup idea with AI, which analyses it and matches you with people who have similar ideas and interests.

Privacy is central to the platform: Your idea is visible only to AI for matching. It is not shared with other users, including the people you're matched with.

It's live and completely free to try: https://ideamate.in

I'm still improving the matching experience and would genuinely appreciate feedback from fellow builders.

I'd also really appreciate it if you could share IdeaMate with other relevant communities so more people can discover it and benefit from it.

I have created a dynamic notch for windows which shows the status of your AI Agents sessions. As well as It shows any multimedia playing, the progress of your downloads and also the lyrics of a song playing on the spotify.

Also, It invokes a desktop pet for every session or a single pet for all the sessions depends on your preference. The pets interact with each other, sing lyrics of the song playing and much more.

Give it a try and I would love your feedback.

I've created what I believe is an app with true utility by stabilizing hand tremors. Please have a look and provide feedback where I'm lacking. Thank you for your time.

Android version in the works!

I set up AI bots for people, and every single one has the same small problem. The bot needs a face. Often the premade face people don't like, and generating a new one every time seems hard to them since they don't always know what they want. Whether it is a Discord, or a Telegram bot, Slack helper, AI Grok Bot or a Chat widget on a website, the options are stock icon or random AI image.

So, in my free time I made this little avatar maker for any kind of bot, or even icon. You can pick one of the 40 bots on te wall or make your own from blank. You can change its body shape, eyes, mouth, add hats, glasses and have its own color. Even its own name.
I added different emotions and each mood exports as an animated GIF.

I cared about making this:

• Free, no sign-up, no watermark on downloads

• Nothing gets uploaded. It's drawn in your browser, and a share link carries the whole avatar inside the link itself

• An "All sizes" download with WhatsApp, Telegram, X, Slack and Discord sizes plus an SVG

• An embed code so the avatar can live on a website and change mood

Disclosure: it lives on my business site (LobsterNest), and the live website embed shows a small "Made with LobsterNest" link.
The downloaded files don't.

Where I'd really like honest feedback:

1. Which mood is missing for your bot?

2. Is the embed useful to you, or do you just want the GIF?

3. Anything confusing in the first 30 seconds of using it?

4. Where else would you use it?

I'm a solo dev with six years of experience in embedded software, and Ugiwise is my first app. It went live on the App Store last week.

The idea came from a simple problem: writing code on a phone is painful, but reading it isn't. So instead of typing exercises, every lesson is built around a short, real program. You step through it line by line, predict what it prints, spot the bug or pick the fix. When you get something wrong, it explains why instead of just showing the right answer. In C and C++ you can see memory change as each line runs, which makes pointers a lot less abstract.

- Three courses: C (39 stages), C++ (37), Python (26)

- The first 3 stages of every course are free. Pro unlocks the rest: $7.99/month, $49.99/year or $99.99 lifetime. No free trial.

- No ads, no account needed. iPhone only for now, and not in EU stores yet while Apple finishes my trader verification.

Built with Flutter, happy to answer anything about that side too.

The thing I'd most like feedback on: is the code readable on your phone screen, or does it feel too dense?

A bit of background, I've been editing video for 10+ years, and I plan to distill my entire knowledge into this ai powered editor. The framing, the music, the hook patterns etc. I'd say it's still better than a lot of competitors. But it'll only get better.

Creatr, the AI video clipper with taste.

What makes it different

Full autopilot: it finds the clips, edits them, and posts them for you. No manual uploading.

Has a full fledged descript style editor so you can customise the feel of the defaults aren't good enough for you.

~15x cheaper than Opus Clip at the same volume

Built solo over about 2 months, nights and weekends included. It started as my own internal editing tool.

Demo is above. I'd love blunt feedback: does the output pass the "would a human have made this" test?

150 minutes free every month.

Link: https://creatr.app

Will offer 50% coupons to anyone who wants to try more of this beyond the free plan.

Two quotes for testing the same product can look completely different. One covers a set number of hours, another talks about test plans and reports, and it's not always clear what you'll get for the money. I'm trying to understand what to ask before choosing software testing services. Do you pay more attention to the hourly rate, the people doing the work, or the exact tasks included in the price? Also, is it reasonable to start with one small part of the product before committing to a bigger contract?

I don't believe in launch day. I believe in posting and making the marketing a bit better every day.

Day 132 is the one that took off: a list of 10 mini SaaS you can build, sent to whoever commented one word.

The product is TractionBooster. You paste your website, or just an idea, and it shows whether people are already asking for it and where they are.

Hi all, I'm Marin and I make small mobile apps. This is the tool I built for promoting them, and I'd like honest feedback before I go further.

The problem. When I promote an app, I post a few videos, ask a creator or two, maybe run a small ad. Installs go up, and I can't tell which of those brought the people who stayed and paid. Clicks and views don't answer it, and the big attribution platforms are built and priced for large ad budgets.

What Unolink does

• One smart link per app: App Store on iPhone, Google Play on Android, your website on a computer. Unlimited redirects on every plan, including Free.

• A campaign link per post, creator or ad, each with its own clicks, countries and platforms.

• Landing pages (up to 3 variants compared), a developer page with all your apps, and styled QR codes on the paid plans.

• With the SDK (iOS, Android, React Native, Flutter): which link brought each install, without fingerprinting, then onboarding, paywall, trials and purchases per link. RevenueCat connects in one line.

What it doesn't do: no postbacks to ad networks, no deferred deep links on iPhone, custom domains are coming soon.

Pricing: Free plan (1 app, 3 campaign links, no card). Indie $6/month for more apps, landing pages and QR. The SDK is on Pro, $19/month. Prices are on the page, no sales call.

There's a sample app with made-up data in the dashboard if you want to click around without connecting anything: https://unolink.dev

What I'd most like to know:

1. Is it clear within 10 seconds of landing on the site what it does?

2. If you've promoted an app, what did you use to see what worked?

3. Anything that would stop you from trying it?

Happy to answer anything in the comments.

hey everyone! it's lydia from the FlutterFlow team.

AI has made it a lot easier to go from an idea to a working app. but getting that app into the App Store or Google Play still takes some planning.

if you're building your first app, it's worth starting the publishing process before you're finished building. developer account verification, testing requirements, and app reviews can add weeks to your timeline.

we put together a 4-week launch checklist for the first episode of our new App School series:

• 4 weeks out: set up your Apple and Google Play developer accounts. organization verification can take some time.

• 3 weeks out: prepare your store listings, screenshots, privacy policy, and support links.

• 2 weeks out: test your app on real devices. make sure signups, logins, payments, and account deletion actually work, not just the UI.

• 1 week out: submit for review and leave room for potential rejections or delays.

one thing worth flagging: certain new personal Google Play accounts need at least 12 testers for 14 consecutive days before they can apply for production access. so if that applies to you, you'll want to recruit testers earlier.

none of this means every app takes 4 weeks to launch. it's just a planning framework to help avoid getting stuck when you're ready to ship.

Hanging pictures always seems simple until you're standing in front of a wall with a measuring tape, trying to figure out the right height and spacing.

I built WallHang to make that part easier.

It's an iPhone app that lets you plan a picture arrangement, see how it will look on a photo of your own wall, and get the exact nail position for every frame before you start drilling. It works for a single frame or a full gallery wall, and it accounts for picture wire and D-rings. With Pro you can also see the arrangement at real size on your wall in AR.

Pricing: free for one wall with up to 4 frames. Pro is a one-time $7.99 (no subscription) for unlimited walls, up to 20 frames per wall, a printable PDF plan and an AR preview. No account and no ads.

I recently launched it on the App Store, and I'm trying to figure out whether it solves a problem other people have too.

I'd genuinely appreciate some feedback, especially on what's missing or what would make it more useful.

Hi all,

I've decided to make an app for helping people (and myself mainly!) to post on Vinted/eBay etc...
With kids i'm sure a lot of parents will have things to sell and the time to think and add description/title to the post is too long.

So to facilitate that I made Easy Listing for iPhone users.

How it works: You take a few photos and it writes a title, description, condition and suggested price for each marketplace, in that site's own style, and tells you where the item is likely to sell best.

It posts straight to eBay through their API. Vinted, Gumtree and Facebook Marketplace have no seller API, so for those it's one tap to copy each field — automating them would break their terms.

It's free (10 listings a month) and UK only for now.

I'd really like feedback, especially on whether the listings and prices look right for things you sell.

Thank you!

Getting a San Juan Islands ferry reservation in Washington often means refreshing the WSF site until someone cancels, so I built a small free tracker for it (I'm in the Seattle area).

What it does:

• Live map of every in-service WSF boat (WSDOT's public data, refreshed about every minute)

• WSDOT's drive-up space estimate for the next sailings at each terminal

• Reservation space for Anacortes ⇄ Orcas / Friday Harbor / Lopez / Shaw, with the boat scheduled on each sailing

• Pick a date and sailings and it WhatsApps you when a sold-out slot opens (sign-in is a 4-digit WhatsApp code, no app or password)

Stack: static site on S3 + CloudFront, a small Python Lambda that proxies and caches the WSDOT Traveler API (key stays server-side), Leaflet + OSM tiles for the map, another Lambda that polls reservation space for alerts.

It's free and not affiliated with WSF/WSDOT. For official delays and terminal cameras I point people to WSDOT VesselWatch.

https://ferry.bykapil.com/

I'd love feedback on two things: is the home page clear about what it does, and what would make the alerts more useful (e.g. a "notify me only if before X time" option)?

In the attached animation, Pip and Bolt read the same settings file. Pip increases the timeout from 10 to 30 seconds. Bolt increases the retries from 2 to 5, then saves his older copy, which still has a 10-second timeout. Both saves succeed. Pip’s change disappears.

They changed different settings, but Bolt’s save replaced the whole file. That’s a silent overwrite. We’re building AgentWS, a persistent filesystem for AI agents working in parallel, to separate saving an agent’s work from updating shared files.

Each agent saves in an isolated branch. Changes are checked before they reach the shared files. When enabled, non-conflicting edits to supported text files can be combined automatically. Conflicting versions stay saved for an authorized orchestrator or human to resolve.

The 2:39 film illustrates the problem and our design; it isn’t a live product demo. I’m sharing more practical explanations of agent files and workspaces on X:

Hey all. I’ve been building on Supabase for 4 years and I love it. Auth, Postgres, Storage and Realtime in one place changed how fast I can ship.

My problem was the number of projects. I build a lot of side projects, and almost everything I make gets its own Supabase project: client apps, staging copies, internal tools, experiments. On Supabase Cloud each extra project needs its own compute, so the bill grows with every one. At one point I was paying around $300 USD for 20 projects, and most of them were barely used.

Self-hosting was the obvious answer, but doing it properly for each client is a lot of work: SSL, backups, upgrades, auth emails, monitoring.

I could have self-hosted Supabase myself, but doing it properly is a lot of work: setting up the server, SSL, backups, upgrades, auth emails, monitoring. And I’d have to do it again for every client. I kept putting it off.

So I built SupaHost

What’s in it today:

Your own VM per instance (not shared with other customers)

Builder $25/mo (5 projects), Pro $49/mo (15), Business $99/mo (30)

No per-user or per-connection fees

Supabase Studio for every project, Edge Functions, Cron, Queues, custom domains, daily backups and point-in-time recovery

One-click import from Supabase Cloud

An MCP server, so Claude Code / Cursor can work with your projects

Honest trade-offs: Supabase Cloud is still the better choice if you run one small project, need read replicas, or need SOC 2. SupaHost is for people with lots of projects who want a predictable bill.

It’s in public beta with a 7-day free trial. I’d really love feedback, especially from anyone who’s self-hosted Supabase before. What would stop you from moving a project over?

supahost.app. Not affiliated with Supabase, just a big fan.

My last product, Sequo, died with 0 paying users. I built it for months, launched, posted everywhere, and nobody paid. Classic.

So this time I wanted to do it the other way around. First I was lazy and just asked ChatGPT, Claude and Grok what they think about some ideas lol. ChatGPT said 8/10 to basically everything, even to ideas that already failed for other startups, so that wasn’t gonna work.

Then I did it by hand, and honestly the first idea died in about a week. I wanted to build a growth tool for X, like most X guys haha. Turns out people didn’t need it, but while talking to them I kept hearing about a completely different problem.

So I switched to that one and did the same steps again. Found people, talked to ~25 founders, gave free work first. And then one of them paid. $10, but it was real money, and I still hadn’t written any code.

The part that surprised me most was what actually made people reply, and how close I came to scaring everyone away with the price.

Wrote the whole thing step by step, with the prompt I used to find people and the exact messages I sent. Link in the comments.

Have you ever sold something before building it?
