### 5/5 — A must have for a Photograper!!!!

*2020-11-28, version 1.1*

I’m so pleased and excited of this amazing app, I’ve always wanted to have something like it to help me get Amazing pictures without being near my camera. This app will let you take photos without being right next to the camera or holding the trigger in your hand.

Convinient and accessible and easy to use! No more cables after cables to take pictures and the best of all is the options to place a timer a photo counter and so on!

Also compatible with my iWatch!!!!

Superb !!!
