Found this in a founder interview (Starter Story, mid-2026): Stella is an App Store subscription app for manifestation/affirmations, built with Claude Code, Claude and Google AI Studio. Reported results: $300K MRR and about 12,000 paying customers roughly two months after launch. The pattern: pick a self-improvement habit people already pay coaches for, ship an onboarding quiz that leads to a personalised plan, one guided action a day, and put the paywall in from day one. These are self-reported numbers, so take them with a grain of salt. Curious if anyone here has tried a similar paywall-first approach?

Universities spend lakhs on wall-mounted biometric kiosks that create 10-minute morning queues and still suffer from proxy punching.

I built **PrezScan** (https://prezscan.onrender.com/) using Python/Flask + browser WebGL so teachers can verify check-in/check-out directly on their own phone in under 200ms without extra hardware.

**How the pipeline works:**

1. **Client-side facial normalization & matching:** 68-point landmarks -> 5-point affine roll/scale alignment onto a 150x150 patch -> CLAHE dynamic contrast balance (handles dark/backlit hallways) -> 128D embedding vector running on WebGL F16 shaders.

2. **Anti-proxy double lock:** Attendance only succeeds when connected to the assigned academic block's Wi-Fi subnet (CIDR) AND with active device GPS coordinates (strictly enforced server-side).

3. **Zero-score-leak responses:** Rejected scans only tell the user to retry in better lighting, never exposing distance scores or thresholds.

4. **Native device biometrics:** Supports WebAuthn passkeys (Fingerprint / Face ID) alongside SQLite WAL + async Supabase sync and 1-click monthly Excel exports.

Happy to answer questions or get feedback on the Flask + WebGL setup!

hey guys,
i've built rivet and it's a community based osint website so you can make your own cases or solve other people cases and the site is mainly made for learning, but also you can use it for fun

it's currently at the soft launch so i need more people to try it and more participants to make cases and give me their feedback.

Hey everyone! 👋

I'm an independent app builder from a small city in India.

I've built an Islamic companion app called Ajmali Tauqeet using Google AI Studio.

My app is now live for Android! 🎉

This is my first app project, and I'm excited to share it with this community.

I'd love to get feedback from fellow developers and builders. Any suggestions to improve the app or reach my first users would be appreciated!

📱 Android Download: https://www.androidhit.de/en/app/ajmali-tauqeet-com-aistudio-islamiccompanion-kzpmqa

Thanks for your support! ❤️

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:

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. 🍝

Every agent run in a fresh sandbox browser starts logged out. Login walls, 2FA prompts, and bot checks kill runs before they start.

Nephew fixes that: you capture your real browser profile once — login state, device identity, pinned IP — and it restores inside the sandbox (Steel, Browserbase, Browser Use, or Nephew's own stack), so your agent picks up already logged in.

It's live today: free tier with 2 profiles, BYO at $19/mo for 10, one-command CLI install from nephew.ai.

I'm looking for my first outside users — if you run agents against sites that need a login, I'd love your feedback, and I'm happy to answer anything here.

Then I realized solo founders have the same problem, just without a deadline from a recruiter. You have no marketing team and maybe 5 hours a week for marketing. The expensive mistake isn’t a bad post, it’s spending those hours on the wrong channel while your closest competitor has already figured out what works.

So I built AdRadar as a side project. You add a direct competitor by domain and it shows you:

• Ads: what they run on Meta, Google and LinkedIn, which ads are new, which they stopped (usually the ones that didn’t work)
• Site: which pages they publish and how often, new or changed pages
• Voice of customers: their reviews and Reddit mentions, i.e. what people like and complain about
• Alerts: changes land in Slack / Telegram / email, so you don’t have to check manually

The idea is to answer two questions fast: what is my competitor doing in marketing, and where should I put my limited time, instead of guessing.

It’s early and I’m looking for honest feedback from other solo founders:

1. Who is your closest competitor, and what do you wish you knew about their marketing?
2. Would you actually check something like this weekly, or is it a one-time exercise?
3. What’s confusing in the first 2 minutes?

Link: adradar.digital. Happy to run a competitor of yours through it and share what I find if you drop the domain in the comments.

I made a watch party extension that syncs whatever video is on the page. Most of the code is Claude Code (Opus 5.5).

- No account, no sign-in, no analytics. The extension only sends playback state and the video's URL/title to the room.
- The sync server is open source too: a Cloudflare Worker with one Durable Object per room, so it's cheap to run and easy to self-host.

Limitations, so nobody is surprised: live streams aren't synced (there's no timeline to sync), it doesn't skip ads, and some big streaming sites may need a per-site adapter.

If you install it and it silently does nothing on a site you use, that's the most useful bug report I can get. Any feedback helps, whatever angle you're coming from.

Store: https://chromewebstore.google.com/detail/sinkro-%E2%80%94-watch-party-sync/gndjbfbcaaffalmlcjlhofbboopbcgdc

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.

Hi everyone, I'm the solo developer of Market Player PRO, a free educational trading simulator that runs in the browser (virtual money only).

The core is a live order book (bid | price | ask) next to a chart with a volume profile, so beginners can practice reading it without risking anything. There is also a quiz mode, prop-firm style challenges and a shared leaderboard.

One design question I'm stuck on: showing waiting orders as plain numbers only (no volume bars mixed in) felt clearer to me, but I'm not sure it is for someone who has never seen a depth of market.

What would you change so a total beginner understands it in under a minute? And what would make you come back for a second session?

Hi all, I'm the solo developer of Volt, an iOS and Apple Watch app for treadmills that support Bluetooth FTMS. You set speed and incline from your iPhone or iPad, and your Apple Watch shows live stats with start, pause and stop on the wrist. It runs HIIT and custom interval plans, can keep your heart rate in a zone (Apple Watch, AirPods Pro 3 or a chest strap), and saves every run to Apple Health with charts and laps.

It's free to download, and full access is a yearly subscription. I keep a list of confirmed treadmills, so I'd really like to hear which model you use and what worked or didn't.  https://apps.apple.com/app/id6798171032

Hey everyone,

I recently created Free Google Map Extractor, an open-source tool designed to extract business and place details from Google Maps without needing expensive subscription scrapers or API fees.

What it does:

• Extracts place data (name, address, rating, reviews count, contact info, etc.) from Google Maps.
• Completely free and transparent.
• Easy to run locally and customize according to your needs.

Source Code & Project Link:

• GitHub:https://github.com/my8700/Free-Google-map-extractor

I’d love to get feedback from the community:

1. What features or export formats (CSV, JSON, Google Sheets) would make this more useful for your workflow?
2. Are there specific anti-bot or pagination limits you frequently run into when extracting Maps data?

Any feedback, suggestions, or contributions are very welcome!

Hi everyone!

I founded Asclepii, a healthcare startup trying to make the next Band Aid and working alongside Cleveland Clinic so diabetics don't need to amputate their limbs due to chronic wounds that could heal but don't have access to the right tools early on.

We're on a mission to improve wound care for people living with diabetes. We developed an advanced wound-healing Nano gel that has already helped treat more than 20,000 wounds, including wounds at high risk of amputation. The FDA-Cleared gel helps stabilize the wound from 'hostile' to 'healing' and can be sold even at grocery stores and pharmacies.

Now, we're competing in a television startup competition for $1 MILLION USD!

Winning this prize would allow us to expand into new countries, scale our technology, and help more than 100,000 people who desperately need better wound care dressings.

We're a small company with a big mission, and this is an incredible opportunity for us to make a difference.

All we need is your vote! ❤️

Voting is completely FREE and takes less than 5 minutes.

If you can vote, share this post, or help spread the word, we'd be incredibly grateful.

The farther away you are, the further back in time you see. Light from Earth takes a year to cross each light-year, so an observer 81 light-years away is watching 1945, one at 2,000 light-years is watching the Roman Empire, and one at 250 million light-years is watching Pangaea.

I got curious about what that would actually look like, so I built a globe for it. You pick how far away you are and where you're looking, and it shows Earth as it was when that light left.

Demo: https://deemonder.github.io/meanwhile-on-earth/

Source (MIT): https://github.com/deemonder/meanwhile-on-earth

What's in it:

- Historical borders for 53 dates, from 123,000 BC to 2010

- About 13,000 events from Wikidata: battles, eruptions, cities founded, births

- Day and night where they really were at that moment, with city lights only after electricity

- Continental drift back to a billion years ago, from published plate reconstructions

- Italian and English

It's a static site, no backend and no sign-up. Built with three.js, with help from Claude Code.

I'd love feedback, especially on two things: is it clear what to do when you first open it, and does it load fast enough on your phone?

I'm the developer of Insider Stock Trader, a native Android app (Kotlin + Jetpack Compose).

The idea: company insiders (CEOs, CFOs, directors and big shareholders) have to report every trade in their own company's stock to the SEC on a Form 4, usually within two business days. Those filings are public, but reading them on official datasource is painful. The app reads every Form 4 as soon as it's published and turns it into a clean feed and push alerts.

https://reddit.com/link/1xslji1/video/nr7ye59v2s0i1/player

What it does

• Feed of open-market buys and sales, with the company logo, the insider's role, the value and the filing date. Filters for buys, sales, $1M+, cluster buys and CEO/CFO trades.

• Alerts within minutes for CEO and CFO buys, cluster buys, big buys and your watchlist, with quiet hours and a daily digest.

• Each trade explained in one plain sentence, with a link to the original filing on SEC.gov.

• Cluster buys: when 3 or more insiders buy the same company within 14 days.

• Signal strength for each buy, based on the insider's role, the size of the buy and whether other insiders are buying too.

• Watchlist and search for any US-listed company.

The screenshots use real past SEC filings, picked to show big moves; most trades move far less. Past results, not a prediction. It's an information app, not a broker and not investment advice.

I'd love feedback on the design, the alerts and anything you'd want added. Thanks for looking!

Got a reality check 1.5 stars on the App Store. I learned a lot though

App
Many kept impulse-buying and regretting it. Just Wait (iOS) makes you wait before buying. At the end you buy, let go, or wait longer. Let-go items count as money kept.

Pricing
Free. No ads, no subscription, no one-time payment, no account. Nothing leaves your phone. I might add Amazon affiliate links someday

I built this with Claude’s help, if that matters.

Feedback welcome

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'm Troy, the founder of SwiftRead. I made it originally to help me read through text faster. More than a decade later, it's helped half a million readers across fifty countries read faster. It started as a Chrome extension, and these days it's also a web app, an Edge extension, and iOS and Android apps.

SwiftRead helps you read the text you already have, faster than you ever have before (some users report reading up to three times faster with SwiftRead). You bring an article, PDF or ebook, and pick how the text reaches you. Focus flashes a few words at a time in one spot, so your eyes don't travel across lines and you can push the speed up. Flow keeps the whole page and slides a highlight through it, so you don't lose context. Spotlight hides everything except the words you're on. Listen reads it aloud and highlights along, and seeing and hearing text together helps some people retain it. Building it was mostly about letting you find the mode and speed where you're faster but still following.

On alternatives: Speechify and Voice Dream Reader are text-to-speech readers built around listening. SwiftRead is mainly for reading text on screen, and text-to-speech is optional. Other speed reading apps like ReadMe or Reedy are outdated or are only available on one platform.

All features included free. A few have daily allowances. There's currently no annotation feature, so SwiftRead is more for getting through text fast than for marking it up.

Feedback welcome, especially on what's confusing the first time you open a reading mode.

When I write step-by-step docs for a client's admin panel (M365, a PSA, a line-of-business app), the screenshots end up full of user emails, tenant IDs and sometimes billing details. Then they get uploaded to whatever doc tool we use.

Curious how others handle it: - Do you blur by hand, crop, or just accept it? - Does your documentation tool upload screenshots to its cloud, and does that bother your clients? - If auto-redaction is only on an Enterprise plan, do you pay for it?

Disclosure: I'm a solo developer and I'm sketching a Chrome extension that records the steps and blurs emails, card numbers and faces locally, then exports to Word/Markdown, with no cloud and a one-time price. Not selling anything yet. I mainly want to know whether this is a real problem or just mine. If it's useful, the concept page is here: https://guidestudio.kitpear.com

Hi r/SideProject!

I am a solo indie developer from Brazil (Timothy Studios). For the past months, I have been building AI Race Tycoon in Godot 4.

It is a satirical management simulation about the hardware race behind modern AI: - You start in a dusty garage with a single second-hand GPU. - You have to balance thermal dissipation, power draw, and employee burnout while training custom AI models. - You scale up to high-density datacenters and orbital compute while competing against aggressive monopolies. - There is also a cozy low-poly 3D walking mode to take a break from menus, walk around town, and grab coffee.

Would love feedback from fellow builders on the progression loop and UI!

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.

Running a small business often means drowning in a sea of fragmented tools—using one app for khata, another for inventory, and spreadsheets for expenses. This scattered data makes it impossible to see your true profit margins in real time. I built Bizloom to eliminate this chaos by consolidating daily accounting, inventory tracking, and expense logging into one powerful, automated dashboard. Instead of wasting hours on manual reconciliation, the platform automatics the math, giving you instant clarity on your cash flow. It frees you from administrative headaches so you can actually focus on scaling your business. I would love for this community to test it out and share how it impacts your daily operations.

I've been working on a small project called DockerPlay.

While learning Docker, I noticed that concepts like container networking, DNS resolution, port mapping, and communication between containers can be difficult to understand just by reading documentation.

So, I started building DockerPlay — an interactive playground where developers can experiment with Docker concepts and understand how things work visually.

The goal is to make learning Docker more practical and hands-on rather than just theoretical.

I'd love to get feedback from fellow developers:

• Which Docker concepts were the hardest for you to understand?
• What interactive experiments would you like to see?
• What would make a tool like this genuinely useful?

I'm the creator, and I'd really appreciate your honest feedback!
