Camera Calculator: Math Solver App
Point the camera at an equation and get the answer. A free Android app with photo math solving, scientific calculator and live currency conversion — built and published by Topweb Technologies. View on Google Play.
The problem
Students and professionals wanted a fast way to check calculations without typing long expressions — and a single app for everyday maths, scientific functions and currency conversion.
What we built
- ✓Camera scan of printed and handwritten equations with instant results
- ✓Standard and scientific calculator (trig, logs, powers, roots)
- ✓Currency converter with live rates (USD, NGN, GBP, EUR and more)
- ✓Clean dark UI, history, one-tap copy
- ✓Play Store listing and a 60-page SEO website for organic installs
How we did it
On-device text recognition for speed and privacy, a maths engine for parsing and solving, and a rates API for currency. Marketed with an SEO microsite (topwebtechnologies.net/camera-calculator-app) and mobile install prompts.
