What each tool does
Photomath is a maths help app. Scan a problem with your phone's camera, including word problems, or type it into the smart calculator, and the app shows a solution, sometimes with more than one method. Each step is explained so you can follow the reasoning. It covers elementary maths through algebra and geometry up to college level.
Duolingo is a widely used language learning app built around short, game-like lessons that make daily practice easy. Duolingo Max is its premium tier, adding AI-powered features that help learners practise and understand their mistakes. The core app is free.

Which should you choose?
Choose Photomath if you are a school or college student who wants to understand maths homework step by step on your phone.
Choose Duolingo Max if you want to learn a new language and would pay for extra AI practice. Beginners can start on the free app and upgrade later.
Can you use both?
