Flash

Flash is a beautifully designed and simple Flashlight App. It comes with a normal widget and a lock screen widget, so you can fast access your Flashlight. Unlike many other Flashlight Apps Flash respects your privacy and doesn't send any of your data. Because of that no special permissions are necessary.

A simple notification helps you to switch it off quickly at anytime you want.

There is also an additional function called Pulse which lets your screen pulsate. You can choose the color and the speed of the pulse.
