content: I have been using this app for about 3 years now and i really like using it. I have purchased a lot of trees but i am very very disappointed when i realized that all the trees i purchased are now not available after the upgrade. I am still a student so i am unable to pay the bill to get premium and my trees back so thats very upsetting. All my previous effort just goes into vein. I used to refer to Forest as the best focus app but not anymore. R
