I got this recommended to me by a friend. This works excellent for anyone who needs short to long periods to focus such as for university. It looks good, it functions well, and right now theres even an option to plant real trees with the coins you earn. I hope this continues with further causes! (When I first got the app, I did encounter a small glitch where I was turning the wheel for the time to grow and the picture in the middle kept sliding to the right instead, but I havent encountered it since.) Great idea for an app and worth it for sure. Would love more plant variation in the future.
