Adaptive Difficulty
10 levels per operation that auto-scale based on your accuracy. Get 80%+ right and you level up. Struggle? It eases back. Always in your sweet spot.
Combo Streaks

Answer in under 1 second for INSTANT bonus. Under 2 for FAST. The speed ring around each problem gives you visual feedback in real-time.
Fizz Bubbles
Ambient carbonation bubbles rise across the screen, matching the name and creating a calming, alive atmosphere. This app literally fizzes.

FAQ
Common questions
What age is MathFizz for?
Everyone. The adaptive difficulty starts at basic single-digit problems and scales up to complex multi-digit calculations. Kids learning arithmetic and adults sharpening their mental math both benefit.
What are stim rewards?
After each practice session, you earn a sensory break — an interactive visual experience like fireworks, gravity balls, or a sound pad. They're designed to reward your brain and prevent math fatigue. Particularly great for ADHD/neurodivergent users.
How does adaptive difficulty work?
Each operation (addition, subtraction, multiplication, division) tracks your last 10 answers independently. Score above 80% accuracy and the level increases. Below 50% and it eases back. You can also manually adjust levels in settings.
Is it really free?
Yes. Free includes 100 problems/day, all operations, adaptive difficulty, streaks, the Neon theme, and unlockable stim rewards — with zero ads. Premium adds unlimited problems, extra themes, and instant access to all 12 stim rewards.
