Doesn't even take a second to start up the App. Once it is started you are ready to bring light in the dark. There are 3 different modes. The torch mode, which is the startup mode where you can switch your app on and off. The morse mode lets you morse signals, also very fast performance of this mode. And we have a strobe mode where you can change the frequency. The frequency is also showed in an indicator. You can also morse any text you want, in case of world end scenario. Furthermore we integrated some sounds and animations, that give you the feeling of real torch. Never be scared in the dark again. Please note that the usage of the flash light can clearly shorten your battery power.
