Logo proposal

Hello, i am a graphic designer and i'd like to contribute a logo to your project, it's free of course.

add more gestures & details on power consumption

I haven't found a single word on how much extra energy that service would consume if left working in background.

As for 'more gestures' feature request, actually, this doesn't relate to the flashlight. I'd like to build a similar background service that would listen to 'triple wrist-twist' gestures clockwise and counter clock wise when the phone is locked to perform two different BLE requests, but I am not quite sure how to recognize such gestures (if possible at all)

add blinking light in order to look more feature

add this with UI in order to add blinking light . I am beginner so I don't know about mobile developement
public void toggle(View view)
{
Button button = (Button) view;
// mine coding for disco light
if(button.getText().equals("Switch On") )
{
int i=1000;
while (i>3)
{
if(i%80!=0)
{
//button.setText(R.string.switch_on_text);
torchToggle("off");
}
if(i%80==0)
{
// button.setText(R.string.switch_off_text);
torchToggle("on");
}
if (i==10000)
{
button.setText(R.string.switch_off_text);
torchToggle("off");
break;
}
i++;
}
}
// mine coding

}
