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.

Your own tutor that never gets tired of your questions. Open SmartWit, pick a chapter in Algebra 1 or Geometry, and start talking. The tutor answers out loud in under a second, and draws on a whiteboard you both share while it speaks. A parabola plotted properly. A triangle with the right angle marked. The board a tutor sitting beside you would use. It works in the other direction too. Write your steps by hand on that board and SmartWit reads them, including the one that went wrong. It rings the line where the sign flipped and asks you to multiply it back out. HOW IT TEACHES Two sentences, then a question back. Ask the same thing five times at midnight and it answers five times without sighing. What it will not do is hand over the answer, because an answer you did not reach yourself is not yours. It draws real math. Every graph and diagram is computed rather than sketched, so the curve is actually the curve, and equations render the way they do in a textbook. It follows the course. Algebra 1 and Geometry track the sequence US high schools use, chapter by chapter. SmartWit keeps a picture of which topics have landed and which keep slipping, and spends the time where it is needed. FOR PARENTS See the learning, not just the screen time. Every session ends in a plain-language summary: what was practiced, where mastery moved, what to keep an eye on, and a short note written to you. You can open any session and watch the whole thing back, voices and whiteboard together, or share a clip of the moment it clicked. WHAT IT COVERS Algebra 1: one-variable statistics, linear equations, inequalities and systems, two-variable statistics, functions, exponential functions, quadratic functions, quadratic equations. Geometry: constructions and rigid transformations, congruence, similarity, right triangle trigonometry, solid geometry, coordinate geometry, circles, conditional probability. WHAT YOU NEED A microphone. Headphones help in a loud room. Camera access is optional, and used only when you choose to photograph work you did on paper. SUBSCRIPTION Every plan starts with a 7-day free trial, and no card is charged during it. Plans are monthly auto-renewing subscriptions: Scholar and Mentor (Mentor adds a 1-on-1 mentor session every two weeks). Payment is charged to your Apple ID account when the trial ends, and the subscription renews automatically each month unless cancelled at least 24 hours before the end of the current period. Manage or cancel anytime in your App Store account settings.

Verdict
The clearest difference is rating: SmartWit at 5.0 against Chalk's 3.6. SmartWit also leads on iOS requirement (15.0 vs 17.0). Chalk's advantage is ratings volume (5 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Chalk sells 7 in-app purchases, starting at $7.99 per month and SmartWit sells 2 in-app purchases, starting at $29.00 per month. Whichever you choose, the download price is not the number that matters.
SmartWit holds the better App Store score, 5.0 against 3.6. That said, the two scores are not equally well evidenced: Chalk has 5 ratings behind it against 1, so its average is the more settled of the two.
