How we checked
On 3 November 2026 we read each app's US App Store page and Apple's lookup data. Subjects, free use and features come from each listing; we did not install the apps or test how often they are right.
Order: first the apps built for homework whose listing says clearly what is free, then the general chat and the study and quiz tools. "Socratic AI" on the App Store is not Google's old Socratic app, so it is not here. For general chat apps, see AI chat apps for iPhone.
