User Reviews

Reviewers mostly praise the app as fun and helpful for practicing math, especially geometry like angles and triangles, and for its teaching-oriented design. Many enjoy the colorful interface and the ability to annotate solutions. However, several reviews note that hints can be vague or unhelpful, which can limit learning. A few users also request more challenging questions and randomized problem sets to keep content fresh.

Pros

Interactive elements like colors and writing on the screen aid solving

Hints are not useful/unclear, reducing learning value

Recent reviews

So it’s great if you know the answers. Makes you feel really smart. However, the clues are not helpful. The two I’ve looked at so far have been inaccurate or incomplete. And at some point you should be given the option to see the solution with an explanation. Otherwise it’s simply a way to feed your ego. You won’t really learn anything.
