Find it difficult focussing on your ever-growing to-do list? The Forest app might just help.

Available now for iOS, Android, Windows Phone, Chrome, and Firefox, the premise of Forest is relatively simple: users must plant a tree whenever they plan on working. If the user leaves or stops the app while in this process, the tree dies. The more time one is spent working, the more bountiful a forest they can create.

The uniqueness of Forest isn't simply within the clever design, rather it's the psychological framework the app creates. Numerous studies show that having goals, even short term like planting a digital tree and working without breaks, pays off with a chemically induced cocktail of satisfaction. Satisfaction, of which, means the occurrence of the reward increases the likelihood it would happen again and again.
