Simple and efective -small in size  the lowest footprint compared to similar apps  probably just the code needed to run it and start the flash. -it doesn't ask for extra permissions  only access to the camera  in order to use the led module. -no ads  no activity monitoring  no backdoors  no selling of your info to third parties. -no frills  no thrills  no extras which most people never use  it just does what it's supposed to. -it doesn't turn itself off when screen is locked (tested on my Galaxy S2) -totally FREE.
