content: Was a good app but unfortunately they chipped away at the free version until it became pretty useless. First limited the unlockable tree species then removed access to previously unlocked premium trees giving an unusable refund because so few nonpremium trees are left then most annoyingly inserted a pop up that tells you all of this every time you click anything at all. Wouldnt have bothered with the review except for the pop up which is more annoying than any ad.
