User Reviews

Users appreciate this app's effective mental math exercises, adjustable timers, and user-friendly design suitable for all ages. However, multiple reviewers note that the timer can be too tight on harder questions, and the inability to revisit earlier sections is a drawback. Input keys might be too small, and the lack of feedback on wrong answers reduces learning potential. Overall, while functional and engaging, improvements in timing flexibility, UI, and learning feedback would enhance the experience.

Pros

Effective for mental math practice with a good variety of exercises
Configurable timer adds challenge and helps with brain training
User-friendly interface with clear instructions and quality graphics
Suitable for different age groups including children and adults
Option to purchase the app to remove ads appreciated

Cons

Timer settings can be too strict, especially for harder problems, causing frustration
Lack of ability to revisit or practice earlier sections after progressing
Numeric keypad/button sizes could be larger or better spaced for easier input
App does not provide correct answers after mistakes, limiting learning feedback
Some UI elements could be improved for better user experience, including feedback sounds or visual cues on correct answers

Recent reviews

Everything I need in a math app. Instructions followed by exercises, configurable timer for added difficulty. Ability to buy the app to turn off ads as subscriptions are becoming commonplace
