Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Mental Math Gym just got a serious upgrade.
4 Workout Categories. Percent & Tips is still here, but now you can train Add & Subtract, Multiply, and Estimation too — each with Beginner, Sharp, and Expert difficulty.
Timed Challenge (Pro). 60 seconds. As many questions as you can answer. Pure pressure. Great for building speed you can actually use.
Your Stats, Front and Center. The home screen now shows your current streak, best streak ever, and total workouts completed — all at a glance.
Instant Feedback. Every answer now gets a color-coded response (green for right, red for wrong) with haptic feedback so you feel it, not just see it. The next question loads automatically so there's no dead time between reps.
Letter Grades. Finish a workout and see your grade — A through F — with accuracy percentage and a shareable summary you can send to anyone who doubts your mental math.
