content: So far Ive been using this app for revision and its great for staying focused an d motivating me. However it is frustrating that literally everything apart from the most basic of options and abilities are only available with a pro account. I dont want to have to pay to stop me from getting distracted by other apps on my phone or planting other types of tree. Most of all I would love it of the ability to plant realt trees and do my bit to save the planet was available to all.
