content: This app is great I am already way more motivated within only 2 days of using it. I bought the premium version because I really like the app but the free version is just as effective at keeping you focused. One thing I would add is a mode where you can put a specific amount of real money in before you start the timer and if you succeed you get your money back and the virtual tree but if you fail your money gets taken and is used to plant reallife trees.
