Im using this on an iPad Pro 9.7 where for the first time, Apple put a camera with flash LED light.
Most iPad apps available only uses the front screen for a light source, while iPhone apps where it uses the flash cannot be downloaded with an iPad. This app does and enables the flash to be used as a light source.
It has S.O.S. and morse code thru the LED lights and audio beeps from the speakers.
It has an advertisement in the bottom but its unobtrusive so it does not distract me. Acceptable for a free app. I could not ask for more.
