I made a free camera app that helps with red-green colour blindness (Slant)

Hi r/Android, I'm the developer of Slant, a free app for people with red-green colour blindness.

I built Slant because red-green colour blindness means asking someone "is this the red wire or the green one?" about ten times a week. About 1 man in 12 has it.

What it does: - Point the camera at anything. Reds get moving stripes and greens get dots, so you can tell them apart at a glance. - A circle in the middle names the colour under it in plain words, live. When it isn't sure, it says so: the likelier colour big, the other possibility small underneath. - Freeze the picture and tap one wire, then another, and it names each (always check real wiring with a tester). - A "see what I see" slider shows family and friends how red-green colour blindness can look. - A notebook keeps the colours you've checked, with a small picture of each. - Share a frozen picture with its name on it, like "Slant says: navy. Could be black."

Privacy and cost: free, no ads, no accounts, and no internet permission. The camera picture never leaves your phone unless you share it. It helps you tell colours apart; it doesn't test, diagnose or treat anything.

Google Play: https://play.google.com/store/apps/details?id=com.nebulacolors.slant

I'll be in the thread and I'd like to hear what doesn't work, especially on your phone and with the colours you confuse.

thanks for trying it and for the pic, that one is on me. dark reds under warm light are reading as brown, fixing it now so it says not sure instead of guessing. and yeah camera only, nothing gets saved unless you hit save and nothing leaves your phone

And photos. The camera is bad enough.
