Everything you need
Built to make you better at calculus.
Calculus Solver isn't just an answer machine. Every feature is designed to help you understand the rule being applied, not just copy the result.
Instant calculus scanning
VisionKit-powered camera with auto-corner detection and manual handle adjustment. Works on printed textbooks, handwritten limit, derivative, and integral problems, and whiteboards. Confidence indicator warns you if a scan is unclear before you solve.
AI-powered step-by-step solutions
Mathpix OCR converts your photo to precise LaTeX, then GPT-4o generates a complete step-by-step solution. Each step names the rule being applied, chain rule, product rule, u-substitution, integration by parts, and explains it in plain language.
Animated tutorial player
Watch a derivative or integral unfold term by term. Terms highlight, move, and morph with each step, built with SwiftUI's matchedGeometryEffect for fluid native animations. Includes play/pause and speed control.
Voice narration
Every step explanation is read aloud using on-device text-to-speech. Works offline. Supports 40+ languages. Toggle on or off at any time from the solution screen or settings.
Multi-language support
The full app UI adapts to your device language. Explanations and voice narration are generated in your preferred language. Supports decimal separator preferences (3.14 vs 3,14) and regional number notation.
Math display preferences
Choose your preferred decimal separator, repeating decimal notation (vinculum 0.3̄, ellipsis 0.333…, or parentheses 0.(3)), and binomial coefficient style (C(n,k) or stacked notation).
Calculus-first, not calculus-only
Limits and continuity, derivatives, integrals, sequences and series, differential equations, and parametric and polar curves, plus the algebra and trigonometry a calculus problem leans on when it needs it.
Scan history
Every problem you solve is saved to your account and synced across devices. Last 10 scans cached locally for offline access. Tap any past scan to review the full solution.
