MathPen

Most math apps make kids tap buttons. This one makes them write — by hand, just like on paper — so they learn the steps, not just the answer.

Built for ages 5–12, it's a calm, ad-free space to practice arithmetic with real handwriting. Kids write their answers and their working directly on the screen, get instant feedback, and build real confidence with numbers.

WRITE, DON'T TAP
• Kids solve problems by handwriting digits, just like on paper
• On-screen scratch work: carrying boxes, borrowing, and a guided long-division grid
• Instant, encouraging feedback

EVERY OPERATION
• Addition — free, with all features
• Subtraction, Multiplication, Division, and Mix — unlock together with a single one-time purchase
• Supports carrying, borrowing, regrouping, remainders, decimals, and negative answers

TELL THE TIME — NEW!
• The Clock module: kids read a real analog clock, then answer their way
• Write the time (6:30), say it in words (half past six), or set the hands themselves
• Available as a one-time purchase

MADE TO FIT YOUR CHILD
• Adjustable digit ranges and question counts
• Optional timer for an extra challenge
• Practice → Score → Review, so kids can see and fix their own work
