Teach io app questions
Is the Teach io app free?
Yes. Installing the app is free, and every learn guide is free to read. Exam practice, retrieval practice, saved progress and badges come with a Student plan from £2.99 a year.
Is Teach io on the App Store or Google Play?
Not yet. Teach io is a web app, so you install it straight from your browser instead: Safari on iPhone and iPad, or Chrome and Edge on Android, Chromebook, Windows and Mac.
Why can’t I see an Install button?
On iPhone and iPad there is no install button: use Safari’s Share menu and tap Add to Home Screen. On other devices, make sure you’re using Chrome or Edge. If Teach io is already installed, the button won’t appear.
Does the Teach io app work offline?
You need an internet connection to load lessons and save progress. If you lose signal, the app shows a message telling you to reconnect rather than an error page.
How do I remove the app?
Remove it like any other app: press and hold the icon and choose Remove or Uninstall. Your Teach io account and progress are not affected.
