What’s the name of this ceiling bounce app?
Anyone has a link?

Lux meter on the Google Play Store worked well for me. It saves the maximum figure recorded so you can go back and look at it. I don’t know how accurate it is as it will depend on the hardware calibration of the light sensor on your phone, but it is great for comparison.

Introducing Ceilingbounce - flashlight testing and runtime graphs for Android

This is a little rough and definitely expects the user to know a bit about both Android and photometrics. If sideloading and file managers are totally foreign concepts, it may not be ready for you just yet. Please do read the README twice before asking for support. Will code for food and/or lights.

For runtime graphs it works on my new Android 7 phone, but didnt on the Android 5 device before that
