A simple flashlight app that easily lights the area around your wrist. The screen set at full brightness and held on; leaving it in this mode can drain the battery. If you tap the screen it toggles down to gray and the brightness is returned to the system brightness and auto-off is resumed.
In the settings you can turn on S.O.S. and Strobe options as well as set the interval for each independently.
