Hey everyone

I've always hated the guessing game of matching test strip colors by eye. I wanted to bring an honest, purely scientific approach to this problem.

So, I combined science and AI to start a project that can read these strips down to the finest detail and slightest color variation. That's how I built

**StripVision**. The goal isn't just to make something flashy, but to provide a tool that is genuinely useful, accurate, and reliable.

Right now, the app has a completely free quota of 100 scans per month. I would love it if people interested in this space (aquariums, pools, water testing) could try it out and give me some honest feedback. I really need to hear what works, what doesn't, and what features you think I should add.

Thanks so much to anyone who takes the time to check it out!

Got the domain. Need an idea.

One sentence is fine. No format.

See you in the comments.

Solo dev here. Built **StripVision** — point your phone at a test strip + the manufacturer's color ramp in the same shot, you get a real ppm number.

The app uses an AI vision model to extract RGB from each ramp patch and the strip pad, then a polynomial color correction (Cheung 2004) strips out camera and light bias, then it interpolates onto the calibrated curve. ±5% accuracy on the validated chemicals.

**Free for 10 readings/month — no card needed.**

I'd really value feedback on:

1. Does the auto-capture (steady-hold ring fills, then fires) feel natural?

2. Result screen readable without explanation?

3. Any test strip brand it gets wrong?

**Honest about limits:**

- 3 of 9 chemicals fully validated; the rest are in calibration (the app labels which is which)

- iOS only (iPhone 11+, iOS 16+)

- Not a medical device — pool / aquarium / hobby use

I'm in this thread for the next few hours — reply or DM with anything: bugs, weird readings, missing features.
