So close

This app works great on almost any version of android, and the overall project is really cool. White screen after login on this iOS version of the app though in 2025.

Apple reviewed this???

Doesn’t register correctly. In continuous cycle of “detecting cosmic rays” and then going back to “register” screen. Can’t understand how Apple lets apps slip by which don’t function at all!

rays and my health.
I am really interested in this app.
