Mental Math - Number King shows promise in boosting mental calculation speed, with sampled reviewers reporting faster thinking and improved math skills, especially in children. Its engaging, step-by-step approach makes basic math strategy fun. However, concerns about incorrect teaching methods (e.g., adding tens before ones), a paywall after early levels, technical issues, and overly short timers were frequently raised. The app may fit young beginners seeking entertaining practice, but may not suit users requiring standard methods or those unwilling to pay.
