Many people in the flashlight community would like to have some kind of idea how their flashlights are performing.
Instead of buying expensive gear, you can just start playing around with your (Android) phone.
There are currently a few apps you can use, but perhaps we can dedicate 1 thread to the different types of Apps, and share your experiences, ideas.
I’ll the the App names here, with references
1. Ceiling Bounce App
