the app is great for scientific calculations for study and it retains the old calculations even if you close the app and you can scroll through an entire session without issues. unlike some reviews stating that it requires permissions in my case it doesn't ask for any permissions and all the permissions in settings are not allowed by default but the app still runs fine.
