Best free option
Photomath
Photomath, owned by Google, is the benchmark in this category. It holds a 4.8 rating from about 733,000 App Store reviews, carries an Editors' Choice badge and supports 32 languages.
Its biggest strength is that basic step-by-step explanations are free. It also handles word problems, draws interactive graphs and now animates individual steps. Photomath Plus adds animated tutorials and textbook solutions for a fee.
The catch: The free steps are deliberately basic, and the deeper explanations live in Plus. If you have outgrown the free tier, our Photomath alternatives page compares where to go next.
