Snap a photo of any math problem and get a clear, step-by-step solution in seconds. Point your camera at a question — handwritten, printed, from a textbook or a worksheet — and get the answer together with the reasoning behind it, line by line. The goal is not to hand you a number. It is to show you how the number is reached, so the next question gets easier. WHAT IT SOLVES • Arithmetic, fractions, decimals, percentages • Algebra — equations, inequalities, systems, factoring • Functions, graphs, logarithms, trigonometry • Calculus — derivatives, integrals, limits, series • Geometry — angles, areas, volumes, proofs • Word problems, statistics and probability • Physics and chemistry problems that need formulas HOW IT WORKS 1. Point the camera at the question, or pick an image from your gallery. 2. Get the answer with every step written out. 3. Still stuck? Ask a follow-up in chat and have it explained a different way. BUILT FOR ACTUALLY LEARNING • Step-by-step reasoning, not just a final answer • Follow-up chat — ask "why does that step work?" as many times as you need • Reads handwriting, textbook pages, worksheets and screenshots • Every solved problem saved to history, ready to review before a test • Fast, clean, one-handed interface • Works in 14 languages WHO IT IS FOR Middle school, high school and university students. Parents helping with homework. Anyone brushing up before an exam, a placement test or a job assessment. Stop staring at a problem you cannot start. Take a photo and see the first step.

Verdict
The clearest difference is review sentiment: Math Solver AI at 67% against KnowNotes's 0%. KnowNotes's advantage is rating (4.5 vs 3.8) and update cadence (weekly vs every 2 months). On price, ratings volume, ads and in-app purchases 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. Math Solver AI sells 3 in-app purchases, starting at $4.99 per 7 days and KnowNotes sells 6 in-app purchases, starting at $5.99 per 7 days. Whichever you choose, the download price is not the number that matters.
KnowNotes holds the better App Store score, 4.5 against 3.8. Both are backed by a comparable volume of ratings — 6 and 13 respectively. Written reviews complicate that: 67% of Math Solver AI's written reviews are positive against 0% of KnowNotes's, so the app with the better star average is not the one people write more warmly about.
Math Solver AI ships an update every 2 months, KnowNotes weekly. The most recent releases landed on September 18, 2026 and September 23, 2026 respectively.
