It is incredibly hard to disconnect from technology in this day and age, especially our phones. This app helps us put down our phone and concentrate on the things that matter. Like getting those essays written. It uses basic psychology to try and prevent us from touching our phone for specific periods of time. Open the app, set the time you want to study for and then a tree will start to grow from a sapling. But if you navigate from the app then you will kill the tree. And no one wants that. There are many other versions of this app some more restrictive than this one. But this one has the added bonus of donating to charity to help plant more trees.
