> I’m on iOS, tried a few but they all wanted a subscription and were a terrible experience without it. So I wrote simplescan.vercel.app / https://github.com/mcintyre94/simplescan which does the job for me! Though Apple have broken using the camera when you save it to your Home Screen and open it as an app which is annoying.

Ah, that explains it! Your usecase explains it, but I'm reasonably assuming Android because recent iOS versions have it built-in.
