# The best AI tutor app for iPhone in 2026: 9 compared

The best AI tutor app for iPhone depends on how you like to study. ChatGPT and Gemini are the most capable free options, and both have a learning mode (study mode, Guided Learning) that guides instead of answering. Gizmo turns your notes into flashcards and quizzes. Gauth and Studdy explain maths from a photo. Ask Poppy is the pick if you want to talk a subject through out loud with a tutor that asks questions and gives hints; it also runs on iPad and Mac, but it's new, with only a handful of ratings.

## How to choose

1. **Answer engine or tutor?** If you need to check an answer fast, a solver is quicker; if you need to be able to do it in the exam, pick something that makes you do the steps. Our [homework help app comparison](/best-ai/homework-help-app/) splits them this way.
2. **Type, scan or talk?** Gauth and Studdy start from a photo; ChatGPT and Gemini from typing or voice; Ask Poppy from talking.
3. **Check the age rule** in the terms, not just the App Store rating.
4. **Try the free tier for a week** before subscribing, and set a reminder to cancel. See [how to cancel on iPhone](/guides/cancel-study-app-subscription-iphone/).
