FastMath – Scan, Solve, Study & Ask FastMath turns your camera into a powerful AI math solver, study companion and homework helper. FastMath 3.x represents a new generation of FastMath, completely rebuilt and far beyond the experience of earlier 2.x and 1.x versions. The app now combines high-accuracy math solving, improved question detection, full-page worksheet scanning, multi-question solving, step-by-step explanations, and AI follow-up questions in one fast and organized workflow. Take a photo of a single math problem or scan an entire worksheet. FastMath detects the questions, solves them together, and presents the answers clearly so you can review the whole page without scanning problems one by one. FastMath is built for high-accuracy math solving, with improved detection, stronger reasoning, more reliable answers, and clearer step-by-step explanations across a wide range of math problems. Need more than just the answer? Open any question to explore a detailed solution, understand how the result was reached, and ask AI follow-up questions whenever something is unclear. SCAN AN ENTIRE WORKSHEET Capture a full worksheet, homework page, or practice sheet in one shot. FastMath can detect multiple math questions from the same image and process them together. SOLVE MULTIPLE QUESTIONS AT ONCE Stop scanning one problem at a time. FastMath identifies the questions on the page and gives you organized answers in one streamlined workflow. HIGH-ACCURACY AI MATH SOLVING FastMath is designed to provide accurate and reliable solutions with improved question recognition and advanced AI reasoning. STEP-BY-STEP SOLUTIONS Select any problem to view detailed solution steps. Follow the reasoning and understand how the answer was reached instead of seeing only the final result. ASK AI ABOUT ANY STEP Have a question about a specific part of the solution? Ask a follow-up question and get an additional explanation directly inside FastMath. BUILT FOR STUDY FastMath is more than an answer scanner. Use it to check homework, review practice problems, understand difficult concepts, prepare for exams, and study more efficiently. ORGANIZED QUESTION CARDS Each detected problem is organized into its own clear card, making it easy to move between questions, answers, and detailed solutions. EXPORT SOLUTIONS TO PDF Select the solutions you need and export them as a clean PDF for studying, saving, reviewing, or sharing. FEATURES • Full-page worksheet scanning • Multiple-question detection • High-accuracy AI math solving • Instant answers • Step-by-step explanations • AI follow-up questions • Homework and study support • Individual question selection • Organized question cards • PDF export • Support for printed math problems • Support for handwritten math problems • Fast camera-based workflow Whether you are checking your homework, studying for a test, reviewing a worksheet, or trying to understand a difficult math problem, FastMath helps you move from question → answer → explanation → understanding in one place. FastMath has been redesigned around accuracy, speed, clarity, and learning, giving you a smarter way to scan, solve, study, and understand math. Some features require a FastMath Pro subscription.

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. Subscriptions renew automatically unless auto-renew is turned off at least 24 hours before the period ends. Manage or cancel in your Apple ID settings.

Verdict
The clearest difference is ads: MathLens at none against FastMath's shown. MathLens also leads on iOS requirement (16.6 vs 18.6). FastMath's advantage is ratings volume (51K vs 6) and rating (4.2 vs 4.0). On price, in-app purchases, monetization model and device support 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. FastMath sells 5 in-app purchases, starting at $4.99 per 7 days and MathLens sells 2 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.
FastMath holds the better App Store score, 4.2 against 4.0. That said, the two scores are not equally well evidenced: FastMath has 51K ratings behind it against 6, so its average is the more settled of the two.
FastMath ships an update every 5 days, MathLens every 2 weeks. The most recent releases landed on October 13, 2026 and September 30, 2026 respectively.
