content: I am a student and am coming up to summer exams and personally I found this the perfect app to help me concentrate with encouragement avoid distractionsprocrastinations and keep me motivated throughout my revision. D All I would add would be that people are more likely to use the app If there is more of a variety of plants that are free. The premium is okaypriced and I have nothing against it I just think that the app would get even BETTER ratings if the developers added some more.
