Num Trainer

Train focus, memory, reaction speed, and mental math with four quick, customizable number games. Practice anytime and track your progress.

Num Trainer is a lightweight app for building sharper number skills through four focused training games. Improve attention, memory, reaction speed, mental math, and logic with short practice sessions you can fit into your day.

Choose your challenge:

• Mental Math — solve addition, subtraction, multiplication, and division problems. • Memory Pairs — remember positions and match identical numbers. • Tap in Order — find and tap numbers from smallest to largest. • Digit-by-Digit Math — remember a number, then transform each digit using the same step.

Adjust the difficulty to match your level, play at your own pace, and review completed sessions in Training History. With a clean, distraction-free interface and no ads or in-app purchases, Num Trainer keeps number practice simple and focused.
