Forest

The idea behind Forest is to use your smartphone less. You set a timer, and if you leave your phone alone, a little cartoon tree grows on the screen. Get tempted by Facebook or play Candy Crush, and you end up with a dead stick.

Your daily forests can be compared, and each successfully grown tree nets you some coins. These can be spent on new tree types to grow. Alternatively, if you’re socially inclined and have amassed thousands of coins (which takes weeks of dedication), use them to donate to tree-growing projects around the world.
