Tally: Mental Math Trainer
Adaptive daily math training
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Five minutes a day. An engine that learns exactly how good you are and serves problems right at your edge. Feel yourself get faster within a week.
Tally makes you faster at mental math — genuinely, measurably faster — with a few focused minutes a day.
No childish games, no ads, no accounts. Just a beautifully quiet training room, an adaptive engine, and numbers that start obeying you.
TRAINING THAT FITS YOU
Every mode tracks its own skill rating. Answer quickly and correctly and the problems grow harder; struggle and they ease off. Tally aims to keep you around 80–85% accuracy — the zone where practice feels challenging, never punishing. A five-problem calibration on first launch means even your first session fits.
EIGHT MODES
• Add & Subtract — from single digits to four-digit carrying
• Multiply — tables through two-by-two digit products
• Divide — exact division, then remainders (real mod arithmetic)
• Percentages — always exact, never rounded lies
• Fractions — add, compare, simplify
• Squares & Roots — squares to 25², perfect roots
• Powers of 10 — the decimal-shifting reflex
• Mixed Gauntlet — everything, blended
FIVE WAYS TO TRAIN
• Practice — ten adaptive problems, untimed
• Sprint — 60, 120, or 180 seconds against the clock
• Zen — endless, no score, ambient calm
• Gauntlet — twenty problems, three lives, rising difficulty
• Daily Challenge — ten problems, date-seeded, the same ten for every
Tally user on Earth. Compare your standing when you finish.
PROGRESS YOU CAN SEE
XP, levels, and ranks from Novice to Grandmaster. A skill graph per mode. Speed trends, your weakest operations detected automatically, and a
training heatmap. After every session, a magazine-style review shows each problem, your time, and the mental-math trick you could have used.
A STREAK WORTH KEEPING
The ember on your home screen grows with your streak — 7, 30, 100, 365 days. Miss a day as a Pro member and a Streak Freeze covers it automatically, two per month. Reminders are gentle, optional, and honest.
DESIGNED LIKE IT MATTERS
Typography-first interface. A flagship dark mode. Custom haptics on every key. Subtle Metal-rendered moments when you get it right. Full Reduce
Motion support. No third-party code, no analytics SDKs — your data never leaves your device.
