Install ZeroTwo for iPhone and iPad from the App Store. The quickest way to the right listing is the download page on zerotwo.ai.
Find the app
- On your iPhone or iPad, open zerotwo.ai/download.
- Under Download ZeroTwo for mobile, tap iOS. The App Store listing opens. On a wide screen the page also shows a QR code that your phone's camera can scan.
- Install the app from the listing.
You can also go straight to ZeroTwo in the App Store. If you already use ZeroTwo in a browser, the footer of the sidebar has a Get apps button. Choose Get Mobile App there to open the same download page. To check you have the right app, see What does the ZeroTwo iPhone and iPad app icon look like?
Requirements
The app needs iOS or iPadOS 26.0 or later. On an older iPhone or iPad, use ZeroTwo on the web at app.zerotwo.ai instead. The same app runs on iPad; see Does ZeroTwo work on iPad?
Sign in
Open ZeroTwo and sign in with the account you already use. The web, desktop and mobile apps share one account and the same conversations, so there is nothing to move. On the sign-in screen you can choose Continue with Google, Continue with Apple, Continue with Microsoft or Continue with phone. See How does phone sign-in work in ZeroTwo? for the text-message code.
