content: It does not interfere when i leave the app even in pro version. Edit If i leave immediately after planting a tree it interferes. But if for example i have planted a 60 min tree and i come after 40 min and leave the app it does not interferes and completes the tree as if i never left. Moreover even after changing all the settings it notifies me of tree completion only when i open my phone and not on its own because of which i have to put a timer along with tree whenever i have to use it
