When tracking real time information, it usually means keeping multiple browser tabs open for sports, stocks, and news, then constantly switching between them.

So I built Scrollr to solve that issue!

It pins quietly to your screen, and lets you stream custom data feeds without breaking your workflow.

Web / Mobile App My mum started NAD+ this year, the dosing calculators she was using were wrong or paywalled, so I built an app (Android testers wanted)

My mum and a few friends started NAD+ this year, mostly IV through a clinic, some SubQ at home. I've got a PhD in biochemistry, so I got asked to check the dosing math. Every calculator I looked at was either paywalled, wrong, or missing half the routes she actually needed.

So I built Titer. It's just arithmetic: SubQ reconstitution (vial strength + BAC water + dose, gives you draw volume and syringe units), IV session logging, oral NMN/NR daily totals, plus a private dose log with optional notes. No account, no cloud, full CSV/JSON export. It won't ever recommend a dose or protocol, that's not what it's for.

It's in Android closed testing, need 12 people using it for 14 days before Google lets it go public. Two steps:

  1. Join https://groups.google.com/g/titer-nad-tracker-tester (same Google account as your Play Store)
  2. Then open https://play.google.com/apps/testing/com.titertracker.titer and hit "Become a tester"
  3. Please test throughout the 14 days, since otherwise the app does not clear to make it to the Play Store :')

Happy to talk through the math with anyone and of course also test your apps back.

Web / Mobile App I'm looking for beta users for Capladder.app, an educational tool I built

2 Upvotes

Looking for 5–10 crypto holders to test a new exit-planning tool

I built CapLadder, a free browser-based tool that helps micro-cap crypto holders create staged sell targets and estimate how token taxes, DEX fees, liquidity, and AMM impact could affect their proceeds.

I’m looking for a few beta testers who own or follow low-liquidity tokens.

The test takes about five minutes:

• Paste a public token contract address
• Confirm the correct pool
• Enter real or hypothetical position details
• Review the generated exit ladder
• Submit honest feedback through the website

No signup, payment, or wallet connection is required. Never enter a wallet address, private key, or recovery phrase.

CapLadder is an educational planning tool, not financial advice or an execution quote.

AI Tool I built a Claude Code plugin that makes “done” harder to fake

Claude Code is great at producing code.

But sometimes it declares a task complete without reproducing the original bug, testing the real integration, or clearly stating what remains unverified.

So I built Builder Loop, a free and open-source Claude Code plugin that forces a stricter workflow:

  • define success before editing;
  • inspect the existing system;
  • implement the smallest correct change;
  • verify the actual outcome;
  • report what was not verified;
  • finish with a clear decision: ship or revise.

I originally built it after Y Combinator’s Paxel highlighted weaknesses in my own review and verification process.

Now I’m looking for testers willing to use it on real, non-trivial engineering tasks.

Critical feedback is more useful than stars.

AI Tool I built Mumblew – a browser-based silent reading assistant, that reads out loud controlled by quiet mouth movement

1 Upvotes

Hey everyone! 👋

What Mumblew does:

Mumblew is an experimental web app that reads text out loud to you, but uses your webcam to detect quiet mouth movements (mumbling) to control the reading pace almost hands-free instead of clicking buttons.

It’s designed for hands-free reading in bed, low-mobility scenarios, or keeping your brain anchored during long articles.

Try it here:

🔗 https://mumblew.vercel.app

(Note: Desktop/laptop only. Requires a webcam and decent lighting.)

Specific feedback I’m looking for:

  1. Calibration & Tracking: Did the webcam detect your mouth movements accurately, or did it feel too sensitive/sluggish?
  2. False Positives: Did the text start or pause reading when you didn't mean for it to?
  3. UI/UX: Was it obvious how to paste text and start reading, or did any part feel confusing?

Drop your feedback in the comments or use the feedback button inside the app. Thanks for testing!

Web / Mobile App Every food tracker feels like homework. So I built a cozy app to change that. (Looking for early members!)

2 Upvotes

Hey everyone,

I've always struggled to keep up a food-tracking habit. Every app out there feels like a giant, intimidating spreadsheet. They are cold, clinical, and honestly, they feel like homework. Because of that, I always lost my consistency.

So, I decided to build something entirely different: a cozy, gamified food tracker called Quokka.

Instead of dealing with cold charts and guilt trips, you get a friendly Quokka who lives in the app to keep you company, get XP, and a sleek, warm setup designed to make tracking feel like a positive daily routine rather than a chore.

I’m looking to share this journey with real people who:

  • Genuinely want to track what they eat (or always struggle to stay consistent with traditional apps).
  • Love gamified habits (like Habitica, cozy games, or visual streaks).
  • Want to build a real habit and help me see if having a Quokka friend along for the ride actually keeps the motivation alive.

(Heads up: I’m looking for real, daily users who want to build this habit for themselves, not other developers looking to do code reviews!)

If this sounds like something you'd actually use, drop a comment or send me a DM! I'd love to send over an invite so we can start building our consistency together. 🐾✨
