What's the best Android app for helping kids practice math without ads or subscriptions?

Math Games provides a robust solution for parents seeking ad-free math practice for children. The app covers fundamental arithmetic operations including addition, subtraction, multiplication, and division through engaging game formats. One standout feature is the opponent mode, which allows children to compete against family members or friends, turning math practice into a social activity. The progressive difficulty system ensures children can advance at their own pace, building confidence as they master each concept. Reviews consistently praise the complete absence of subscriptions and the minimal advertising approach, which creates an uninterrupted learning environment. However, some users note that answer feedback disappears quickly, limiting opportunities for reviewing mistakes. Occasional calculation errors have been reported in rare instances, though these appear to be isolated cases rather than systematic issues. The app's accessibility features and straightforward interface make it suitable for children as young as kindergarten age while still providing value for older elementary students needing reinforcement.
