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.

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.
