We have kept the app content free for 3 years. The content were written by a top rated physics instructor to hopefully help a lot of students master physics concepts. For the minimal subscription fee you are able to get access to these contents and lots of practice materials. We think it is a fair price. If you notice, we are frequently updating the app, making it more and more useful. Therefore, it is a continuing effort that requires a lot of work by software engineers and content creators. Without the subscription model, we do not think it is sustainable.
Font size too small

Thanks for liking our app! Most places, such as, chapter contents, practice and challenge questions can be zoomed in. In the next app version, we will try to make Quiz and Formula also zoomable.
Good app for review
