Are you the type of person who struggles not to glance at your iPhone repeatedly when you should be working? Haha who am I kidding, of course you are, we all are. One app that may help is called Forest, which I recently discovered via The Modern Desk. It's basically a cutesy version of a pomodoro timer.

The idea is simple:

1. When it's time to concentrate, open the app and plant a tree.
2. Over the course of 30 minutes (or another time you set), the tree grows.
3. If you exit the app before the timer is up, the tree dies :(

Over time you actually create a little digital forest you can look at later to see how successful you've been (or not been) over the last bunch of sessions. The harder you work, the lusher your forest is.

The app is a mere $1 on the App Store. A tiny price to pay to break your iPhone addiction.
