Scan any math problem with your camera and get the full solution. Every step explained, not just the answer. MathLens is the homework helper that teaches you the method, so you can solve the next one yourself. SNAP IT. SOLVE IT. UNDERSTAND IT. Point your camera at a problem, printed in a textbook or handwritten in your notebook, and MathLens reads it and solves it. No typing equations into a calculator, no hunting for symbols on a keyboard. GUIDED MODE: SOLVE IT YOURSELF This is what makes MathLens different from every app that just prints an answer. In Guided Mode you get one hint at a time. Try the next step on your own. Stuck? Tap Show Next Step. Still stuck? Reveal Full Solution is always one tap away. STEP-BY-STEP SOLUTIONS Every solution breaks into numbered steps with the reasoning behind each one: factoring, the quadratic formula, substitution and elimination, limits, derivatives, integrals, geometry proofs and trigonometric identities. ANSWERS THAT MATCH YOUR GRADE Set your study level, from Kindergarten and Primary through Middle School, High School and College, and every explanation is written for that level. YOUR AI TUTOR, ON CALL Ask a follow-up in plain language: why did you square both sides, explain that step again. The AI Tutor covers Math, Physics, Chemistry, Biology, History, Geography and Literature, and it remembers the problem you are working on. TURN ANY TOPIC INTO EXAM PRACTICE Type a topic, snap a worksheet, or upload a PDF or a recorded lecture. MathLens generates practice questions with study notes and a full answer key. See answers as you go, or take it as a quiz and get scored at the end. Ideal prep for SAT, ACT, AP, IB and finals. NOT JUST MATH Switch subjects right on the camera: Math, Physics, Chemistry, Biology, History, Geography, Literature, or General for anything else. Translate mode reads text from any page and translates it into 100+ languages. WRITE IT, SAVE IT, EXPORT IT No camera shot available? Open the Draw Board and write the problem with your finger or a stylus. A full scientific calculator is built in. Every problem you solve is saved to History, and any solution or study set exports as a PDF. MATHLENS PRO MathLens is free to use with daily limits. Pro removes the limits with a weekly or yearly subscription. Payment is charged to your Apple ID at confirmation of purchase.

Verdict
The clearest difference is monetization model: Pinu at free against MathLens's free with in-app purchases. Pinu also leads on rating (4.2 vs 4.0) and chart position (#55 vs unranked). On price, update cadence, 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. MathLens sells 2 in-app purchases, starting at $4.99 per 7 days and Pinu sells 6 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.
Pinu holds the better App Store score, 4.2 against 4.0. That said, the two scores are not equally well evidenced: Pinu has 43 ratings behind it against 6, so its average is the more settled of the two.
MathLens ships an update every 2 weeks, Pinu every 10 days. The most recent releases landed on September 30, 2026 and October 10, 2026 respectively.
