About

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.
