5 stars: *please read my edit fellow mathletes* So I just upgraded to the paid version, supposed to be ad-free(not the reason I upgraded, however), and i still have ads popping up. Am I missing something? * so after speaking with the developer, really helpful, and quick to answer BTW, it was determined that there are 3 different purchases, and i did not purchase the ad-free, but the main training aspect. So dbl-check if anyone else has this issue.
4 stars: Enjoy challenging myself. Can do it any where. No explanations of how the sections work though.. if you need support just email and you will get a really quick answer. It has really helped me with my mental maths. My favourite app.
4 stars: Big bummer. I was using Matix every day to help with my memory arithmetic. Unfortunately the training sessions are no longer free. I would have gladly paid for *new* features, but it creates trust issues when features start disappearing behind a pay wall.
3 stars: I went through all the way to the end and I finished on 1586 tix and level 142. I worked really hard for 30 minutes every day. Some of the problems are very easy, but most of them up in the higher levels are ridiculously hard. Also, I am disappointed with the ending, after I completed the final boss fight three times. No medal, no balloons, nothing. There weren't even fireworks! Just,
3 stars: Children's account can't use. Update for Developer: Check out ibisPaint and Pixel Studio Family... they have an in app ...
