Photomath
Point your camera at any math problem and get instant step-by-step AI explanations — from arithmetic to calculus.
Overview
Photomath is a camera-powered math learning app that lets students photograph a printed or handwritten equation and receive a fully worked, step-by-step solution in seconds. Originally a demo built on MicroBlink's OCR technology, it went viral after debuting at TechCrunch Disrupt London in October 2014 — unseating Facebook Messenger as the top free iOS app within days. It has since grown to over 220 million cumulative downloads across iOS and Android, supporting arithmetic through introductory college calculus in 32 languages.
Acquired by Google in June 2023 (announced May 2022, EU-approved March 2023) for an estimated ~$550 million USD — the largest startup exit in Croatian history — Photomath now operates as a standalone Google product. The free tier provides unlimited symbolic math solutions with no account required; the paid Photomath Plus tier adds AI-powered animated tutorials, voice-over narration, textbook-specific deep-dive solutions, and contextual hints. No public developer API is offered.

ASEAN Perspective
Photomath in Southeast Asia
Photomath's broad language support (32 languages) and fully free core tier make it accessible across ASEAN's diverse education markets, particularly in countries like the Philippines, Indonesia, Vietnam, and Malaysia where smartphone penetration is high and supplementary tutoring costs can be a barrier. Academic research in the Philippines (2024–2025) found measurable improvements in senior high school students' algebra independence after Photomath intervention. However, the app's Photomath Plus textbook solutions are built primarily around US-published curricula, so ASEAN students using local textbooks will get less value from the paid tier and should rely primarily on the free step-by-step solver.
Photomath is one of the most polished and genuinely useful AI-for-education products available today. Its camera-to-solution workflow is near-instant, the free tier is genuinely comprehensive (no paywalled core features, no account required), and app-store ratings consistently sit above 4.2–4.6 out of 5 across hundreds of thousands to millions of reviews. Coverage is reliable from elementary arithmetic through introductory college calculus, and its acquisition by Google brings long-term platform stability.
That said, the ceiling is real: engineering-level subjects (thermodynamics, circuits, fluid mechanics) and advanced proof-based mathematics fall outside its scope. Some users report frustration as features migrate to the Plus paywall, refund windows are short, and there is no developer API for third-party integrations. For ASEAN students, the app works well across the region's K-12 curricula in English and several regional languages, though localised textbook mappings in Plus are skewed toward US/Western syllabi.
What people say
4.6 out of 5 across more than 729,000 App Store ratings, and 4.2 out of 5 across 3 million-plus reviews on Google Play — Photomath's numbers are hard to argue with for a free math app. Point the camera at a problem, printed or handwritten, and it walks through the steps in seconds, no login wall in the way.
The catch shows up once you hit the Plus paywall. Animated tutorials, textbook-matched solutions, and voice-over walkthroughs run $9.99 a month, $7.99 on the six-month plan, or $69.99 a year — and a chunk of one-star reviews are just people annoyed a feature they liked moved behind that line. Accuracy also wobbles on messy handwriting and multi-step algebra, and there's still no public API for anyone who wanted to build on top of it.
Since Google closed its roughly $550 million acquisition in mid-2023, updates have kept coming rather than stalling out, which isn't a given after big-tech acquisitions. For K-12 and intro-college math, it remains one of the more reliable free tools around; anything past calculus is outside its lane.

Notable facts
- Photomath began as a demo app to showcase MicroBlink's banking OCR technology — its consumer success was entirely accidental.
- Within days of debuting at TechCrunch Disrupt London in October 2014, it knocked Facebook Messenger off the top spot on the iOS App Store.
- Google announced the acquisition in May 2022 but had to wait over a year for EU regulatory approval before completing the deal in June 2023.
- At the time of its Series B fundraise in early 2021, Photomath was resolving 2.2 billion math problems every single month.
