Well I like the app and it truly helps me stay focused, combined with some time restriction methods it's good (although those ones are short times plus breaks), achievements are boring and not good enough, they try to make you pay for extra, but the app itself is not exciting enough to pay, the achievements are not really worth it and it's hard to unlock new trees even with pro version. No new campaigns are launched & collecting coins is not an easily achievable task, too hard to get new trees.
