Theo
Read full descriptionHide full description
Theo is a math tutor for real studying. Snap a problem from your homework, and Theo teaches you how to solve it. You work it out with a pen and paper, the way you will on a test, and Theo reads what you wrote and marks it in red. It doesn't just hand you the answer. It teaches you to get there yourself. HOW A LESSON WORKS • Snap your problem. Take a photo, or pick one from your library. Theo reads it, equations, fractions and all. • Theo checks the basics first. Every problem rests on a few things you were taught before. Theo asks about them one at a time, so the lesson starts from what you actually know. • Anything missing is taught on the spot. Theo shows you why it works instead of handing you a rule to memorize. • Then Theo teaches your problem, start to finish, in short pages you can follow. • Every lesson ends with a recap: just the steps that solved the problem, in one place. ANSWER ON PAPER Theo has no math keyboard. When it asks you something, you write your answer on paper and take a photo. Not sure? Write "I don't know." That's an honest answer, and Theo will work with it. RED PEN FEEDBACK Theo reads your handwriting and marks your own page in red: what you got right, where it went wrong, and what was missing, with a note beside each mark. You see your mistakes on your own work, not described somewhere else. LESSONS THAT KEEP UP WITH YOU Theo listens to your answers as you go. When something isn't landing, it takes smaller steps. When you've got it, it moves faster. PRACTICE SESSIONS When your answers show something you're missing, Theo sets up a practice session on just that idea. It waits for you in Sessions, along with any lesson you haven't finished. WHO IT'S FOR Middle and high school math, from pre-algebra to calculus.

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 device support: SmartWit at 3 against Theo's 1. SmartWit also leads on iOS requirement (15.0 vs 17.0). On price, ads and in-app purchases there is nothing between them.
