Magical Share files with the light, just with a camera and random QR codes. The app convert your files to fountain code in encrypted form and the other device get this code with a camera and then decrypt to the oroginal file. No wifi, bluetooth or internet is needed. The file transfer also dont leave a digital trace. The play store app is released, app store is under review, macos is also released. I want your feedback about the app and how to improve it.
