This app is a very playful app. I use this app as a game. But I have faced some problems using this app. I can use other apps (phone based app/given by phone authority) while 'FOREST' app is active in the background. But on some apps (the apps I have installed by myself ) the forest app does its job. When I get into other apps the tree I have planted on FOREST app should have died but the forest app is not working on phone based app/given by phone authority.
