## Review summary

Users appreciate the app's convenience in providing the Teaching Textbooks geometry course on mobile and the ability to solve problems onscreen. However, they report frequent crashing, a childish interface inappropriate for older students, slow and tedious lectures, and technical issues with the TTS feature and proof mode. While longtime Teaching Textbooks users value having an app version, these problems affect usability and enjoyment.

### Pros

- The app integrates well with the Teaching Textbooks course, which users have used and liked for years.
- It allows solving problems directly on the screen, eliminating the need for paper, making it convenient for mobile use.
- The app offers the same content as the textbook, making it a good mobile version for Teaching Textbooks users.

### Cons

- The app crashes frequently, causing users to sign in repeatedly which is frustrating.
- The presentation is geared towards young children, which does not suit older students studying geometry.
- The app has slow, long lectures that can be boring and may discourage users from enjoying math.
- The text-to-speech (TTS) feature is problematic, sometimes not stopping properly, and there is no option to adjust settings.
- Recent updates introduced bugs in proof mode where correct answers are marked incorrect.
