Snapi

Snapi is an app that lets you take a picture with your Android without having to press the screen or a button. Instead all you have to do is open your palm facing the camera and then close your hand into a fist to activate the shutter.

The settings in Snapi let you set the amount of time to elapse between the closing of your fist and the taking of the picture. The default is two seconds – plenty of time to put your best face on – but if you need more time, you can set it to five or ten seconds. Other options let you activate sounds for the countdown and the taking of the picture. You can also switch between 50 and 60 hertz.

Snapi is an excellent app for taking selfies, since it makes the process easier and doesn't require you to touch the screen. You can set your phone on a table or another surface and take the picture from afar. In short, it's very useful for anyone who likes taking selfies.
