Build a daily mental math habit in minutes. Four modes, four difficulties, three answer styles — drill arithmetic, percents, squares, and sequences your way.
Calcula is a focused mental math trainer built for daily practice. No ads, no clutter — just clean drills that get sharper the more you use them.
Pick a mode, pick a length, and go. Five minutes a day is enough to feel the difference.
FOUR GAME MODES
• Standard — addition, subtraction, multiplication, division. Toggle on whichever you want to drill.
• Percent — find X% of a number. Built for tips, discounts, and quick estimates.
• Squared — squares, cubes, and square roots.
• Sequence — spot the pattern and predict what comes next.
THREE ANSWER STYLES
• Type — punch the answer on a clean keypad.
• Reveal — solve in your head, then self-grade.
• Multiple Choice — pick from four options.
Switch between them anytime to match how you want to practice.
FLEXIBLE SESSIONS
Choose time-based (30s, 1m, 3m, 5m, or unlimited) or solve-based (10, 20, 40, 100, or unlimited) sessions. Quick warm-up or long focus block — your call.
FOUR DIFFICULTIES
Easy, Medium, Hard, Insane. The numbers scale with you. Insane is exactly what it sounds like.
STREAKS, LEVELS, AND AWARDS
• Set a daily goal and build a streak.
• Earn XP for every correct answer and level up.
• Unlock 12 achievements — from First Steps (100 solved) to Iron Will (a 30-day streak) to Insane Master.
DETAILED STATS
See your accuracy, average solve time, lifetime totals, per-operation breakdowns, and best runs. Watch yourself get faster.
DESIGNED FOR FOCUS
• Beautiful light and dark themes built around a single accent color.
• No accounts, no ads, no tracking, no notifications you didn't ask for.
• Everything stays on your device.
Calcula is for anyone who wants to keep their head sharp — students prepping for tests, professionals who do math on the fly, parents brushing up alongside their kids, and anyone who just enjoys a clean mental workout.
A massive 2026 redesign. Calcula has been rebuilt from the ground up with a cleaner look, four full game modes, three answer styles, and a new achievements + streaks system to keep your daily practice on track.
