## What is Calcular?

What if you could sharpen your math skills without ever looking at a screen?

Calcular is the first voice-powered mental math trainer that lets you practice arithmetic entirely hands-free. Problems are read aloud, and you answer by speaking — no tapping, no typing, no staring at your phone. True mental math, the way it should be.

Practice while you commute, exercise, cook, or relax. Calcular turns any moment into a brain training session.

KEY FEATURES:

• Fully Voice-Driven Gameplay
Every problem is spoken aloud and your answer is captured through speech recognition. Keep your eyes on the road, your hands on the wheel, and your brain in gear.

• 4 Difficulty Levels + Adaptive Mode
Choose Easy, Medium, Hard, or Expert to match your skill level. Or select Auto and let the app adapt to you in real time — it adjusts difficulty mid-session based on your performance, dropping down when you struggle and rising when you're on a roll.

• Rating System
Track your skill with a chess-style Elo rating that rises when you answer correctly and drops when you miss — harder problems are worth more. Watch your rating evolve on a detailed chart with preset time ranges.

• Times Table Mastery Map
See exactly which multiplication facts you've mastered with a color-coded 12×12 heatmap. Spot your weak points at a glance and focus your practice where it matters.

• Streak-Based Challenges
Set your target from 5 to 100 consecutive correct answers. Build momentum, stay focused, and push your limits.

• Smart Progress Tracking
Track your daily streak, weekly activity, accuracy by operation, and most-missed problems. Watch yourself improve over time.

• Apple Intelligence Insights
Get personalized tips and encouragement powered by on-device AI after every session and on your progress dashboard.

• 18 Achievements to Unlock
Earn badges for streaks, accuracy, dedication, and mastery across all operations and difficulty levels.

• One-Time Premium Upgrade
Unlock multiplication and division with a single purchase. No subscriptions, no ads — just math.

Calcular speaks your language — available in English, French, German, Spanish, Italian, Japanese, and Chinese with full voice support.

Download Calcular and start training your brain, hands-free.
