The math tutor that teaches — not just answers. Chalk draws every step on a real whiteboard in human handwriting, explains its thinking out loud, and asks you the right questions along the way — like a great tutor at the board. Write a problem with Apple Pencil, type it, or scan it, and work through it together. WATCH IT DRAW Every step appears on the board stroke by stroke — equations, graphs, diagrams — in real handwriting, never a wall of text. HEAR IT THINK Chalk talks you through each move in a natural voice, so you follow the reasoning, not just the result. IT CATCHES YOUR MISTAKES Write your own work on the board and Chalk checks it live, underlines the exact step that went wrong, and shows you why. IT NEVER JUST GIVES ANSWERS Chalk guides you to the solution so you can do it yourself on the test. Parents and teachers approve; answer-scanner apps don't teach. EVERY COURSE, ONE TUTOR Pre-Algebra, Algebra 1 & 2, Geometry, Trigonometry, Pre-Calculus, Calculus, Linear Algebra, Statistics and more — with lessons that adapt to your pace and progress tracking that shows your mastery climb. MADE FOR iPHONE AND iPAD Full whiteboard with Apple Pencil support on iPad, and a beautiful board built for one hand on iPhone.
