Scan. Solve. Done.
You are the one holding a messy homework sheet, a whiteboard full of integrals, or a textbook problem you just want to check. Open ScanCalc, point your camera at the math, and the answer appears — instantly. No typing, no formatting, no hunting for the right button. Just point and shoot. ScanCalc recognizes printed and handwritten expressions, from simple arithmetic (12 × 45 + 78) through algebraic equations (3x + 5 = 14) all the way to calculus derivatives and integrals. The result is displayed right over your camera preview, so you never lose context. You stay in the flow of solving, not tool-switching.
Every Calculation Stays on Your iPhone
ScanCalc processes every image entirely on device using Apple's Vision framework and Core ML. Zero bytes leave your phone. No cloud upload, no account sign-up, no WiFi required. For the student in a test hall with airplane mode on, the engineer on a factory floor without reception, or the researcher working with sensitive problem sets — ScanCalc works exactly the same as it does at home. Your expressions, your work, your privacy. We don't see a single digit, and we designed it that way from day one. The app asks for camera permission and nothing else — no location, no contacts, no storage access.
From Algebra to Calculus — On Device
ScanCalc's neural engine handles five categories of math out of the box: (1) Arithmetic — integers, decimals, fractions, percentages, and order-of-operations expressions; (2) Algebra — linear equations, quadratic equations, systems of two variables, and inequality solutions; (3) Trigonometry — sine, cosine, tangent values and trigonometric identities; (4) Calculus — derivatives, indefinite and definite integrals, limits; (5) Statistics — mean, median, mode, standard deviation from tabular data. Each recognition pass runs in under 500 milliseconds on an iPhone 12 or newer, with over 98 % accuracy on clean printed text and 93 % on moderate handwriting. When the camera sees a complex expression, the bounding box highlights each term so you can verify the scan before accepting the result.
Built for Three Kinds of Math Moments
Middle and high school students use ScanCalc to check homework step-by-step. Snap a page, verify your final answer, and move on — no copying mistakes from keying into a traditional calculator. Exam takers working in restricted environments rely on the fully offline mode. ScanCalc needs no network at any point — launch, grant camera access, and solve. University students and working engineers handle multi-term expressions and symbolic notation that are painful to type into a graphing calculator; a single photo replaces ten minutes of careful input. The result history keeps your last 200 scans, so you can scroll back through an entire problem set without snapping again.
Your Workflow, Your Choice: ¥12/Month or ¥38 Lifetime
ScanCalc offers two simple plans. The monthly subscription at ¥12 (≈US $1.70) gives you unlimited scans, full math category support, and result history across all your devices signed into the same Apple ID. The lifetime purchase at ¥38 (≈US $5.30) unlocks everything forever — one payment, no renewals, no expiration. Both plans include a 7‑day free trial so you can run real homework, real exams, and real engineering problems before committing. There is no free tier with ads and no feature gating behind a more expensive plan; the only difference between monthly and lifetime is the billing cycle. Students on a budget pick lifetime once and never think about it again.
What Early Users Are Saying
"I used to type every problem into a graphing calculator — now I just take a picture and it's done. ScanCalc caught a sign error in my final answer that I'd already copied wrong twice." — Liu, Grade 11, Beijing
"During my engineering midterms we aren't allowed phones with signal. ScanCalc in airplane mode was the only calculator I needed. It handled the Laplace transforms that would have taken me ten minutes to type." — Aisha, Mechanical Engineering, Shanghai
"My eight-year-old can scan her math homework herself. The camera recognition is fast enough that she doesn't lose patience, and since there's no internet required I don't worry about what she might stumble into." — Chen, Parent, Guangzhou
"I write my derivations on a whiteboard in my home office. ScanCalc reads my handwriting from three meters away and gives me the numeric check in under a second. It's replaced my physical scientific calculator entirely." — Dr. Murali, Research Scientist, Singapore
