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 hands you the next step to try — 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 TEACHES, AND IT ANSWERS WHEN YOU ASK Chalk works the problem with you a step at a time, shows the reasoning on the board, and lets you try the next one yourself so it sticks for the test. Ask for the answer outright and you get it, with every step shown. 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.

Verdict

The call

Bunpo and Chalk both sit at 4.9 stars, but that hides the real split: 100% of Chalk's written reviews are positive against 72% of Bunpo's. Chalk also leads on update cadence (every 4 days vs every 9 days). Bunpo's advantage is ratings volume (18K vs 2). On price, rating, ads and in-app purchases there is nothing between them.
