Mobile app that solves math problems using smartphone camera and OCR (optical character recognition). Launched October 2014 by Croatian startup. Shows step-by-step solutions. 300+ million downloads by 2023. Acquired by Google (2022).
How It Works
- Point camera at printed or handwritten math problem
- App recognizes equation via OCR
- Displays answer instantly
- Tap for step-by-step explanation
- Multiple solving methods shown
Handles arithmetic, algebra, trigonometry, calculus, statistics, geometry. Free basic version, Photomath Plus ($9.99/month) for detailed explanations, custom visual aids.
Viral Launch
TechCrunch Disrupt 2014 launch went viral. “Magic” experience: point camera, see answer. Students amazed, teachers alarmed. Downloaded millions of times within weeks. “The future of cheating” headlines vs. “Learning tool” defenses.
Learning Tool vs. Cheating App
Defenders argue: Like having tutor—see where you went wrong, understand steps. Better than just copying answer from back of book. Builds confidence for struggling students.
Critics argue: Temptation to skip thinking, just photograph homework. Doesn’t develop problem-solving skills. Students dependent on app, can’t function without it.
Reality: Usage varies. Some students genuinely study steps; others photograph, copy, move on. Intent hard to police.
COVID-19 Surge
Remote learning drove downloads. Parents helping with math homework used Photomath (forgotten how to factor polynomials). Students doing homework alone leaned on app. Teachers couldn’t monitor—camera on or off, who knows what students looking at.
Handwriting Recognition
Later versions improved handwriting OCR. Students can write problem on paper, app reads it. More natural than typing equations. Accuracy improved via machine learning, millions of user photos training data.
Google Acquisition
Acquired by Google (May 2022) for undisclosed amount. Integrated into Google Lens, expanded reach. Strengthened Google’s education technology portfolio alongside Google Classroom, Chromebooks.
Alternatives
Microsoft Math Solver, Wolfram Alpha, Symbolab, Mathway. ChatGPT (2023+) can solve with explanations. Free AI erodes paid subscription apps.
