As mentioned in the title, I am working on an iPhone app for colorblind people (myself included). The app is basically a camera, and it shifts the problematic colors (for your type of colorblindness) towards colors that are easier to differentiate.
I have a mild protanomaly, and I've found this app to be very useful when I am unable to differentiate between red/green or blue/purple on charts, fruits, etc.
If you have any form of colorblindness and have an iPhone/iPad, I would love to give you access to the beta and gather some feedback to improve it further. Just send me a DM, and I'll invite you to TestFlight.
