content: I have been using this app on pro version for more than two years and it is perfect. The core function is so useful for ensuring I stay on task the graphics are cute and I can compete with friends to see who has done the most study each week I think what would be nice is more functionality with the friend concept like if I could send some gift or sticker to cheer them on. I also think a checklist system would be beneficial. Overall though I love Forest and will continue to use it
