This Application packs in 4 different features.
1. It serves as a flashlight app, it sets the screen brightness to the max.
2. 'Flash text' Type a text and flash it, let your friend know what you want to tell without saying a word! :) Phone keeps on flashing the text till the user presses the back or the home button.
3. SOS feature: In emergency situations you may wanna use the SOS feature to alert others, just tap the button and the screen flashes the SOS signal.
4. Finally 'Morse code' Type any text and phone flashes the morse code. Just for fun! :)
This is a freeware. Please do not leave bad comments as a lot of effort has been put up.
