Algebra, geometry & calculus
Free · In-App Purchases · Designed for iPad. Not verified for macOS.
New: tap "Practice math" with Siri to jump straight into your daily review queue. Two minutes a day is enough.
Math, made simple.
Mathio is a calm, focused math trainer for algebra, geometry, calculus, and trigonometry. No distractions. No leaderboards. Just you, clear explanations, and a daily streak.
▸ ADAPTIVE LESSONS
We pick the next topic for you based on your mastery — never wasting time on what you already know.
▸ STEP-BY-STEP SOLUTIONS
Wrong answer? You see the full worked solution inline. Never just "Not quite."
▸ SPACED REPETITION
Overdue questions surface in a daily Review queue using Leitner intervals (1 day → 3 days → 1 week → 2 weeks → 1 month). Scientifically proven to stick.
▸ DAILY STREAK + FREEZES
Build the habit without the guilt. Auto-spent freezes protect your streak when life gets busy. One refill per week, max two banked.
▸ FORMULA REFERENCE
Bookmark formulas as you learn them. Bilingual reference always one tap away.
▸ NO LATEX KEYBOARD
Just type plain text — 6x+2, sqrt(2), pi — and we parse it. No special symbols required.
▸ OFFLINE-FIRST
Everything stored on your device. No tracking, no analytics, no third-party SDKs. Audit our privacy manifest in the App Store.
▸ DARK MODE + ACCESSIBILITY
Full semantic palette adapts to system. VoiceOver labels on every interactive element, including spoken-form math.
▸ GERMAN + ENGLISH
Fully localised, including formulas and step-by-step explanations.
