It is more than a Flashlight app. It uses your Camera LED.

Features:

--Simple Turn on/ Turn off
--Practical app.
--SOS mode -> If you need to help at night, you can use SOS mode. It makes blink the flash. Also you can adjust blinking frequency easily. It may help you to communicate(slow blinking, fast blinking).

*** LED is a hardware part of the camera. To enable LED, access to the camera flash is required. So we need to camera permission.
