Install iSureType on your iPhone
iSureType ships through Apple TestFlight while it's in beta. Once it's installed, the keyboard has to be enabled in iOS Settings — iOS gates every third-party keyboard behind an explicit Full Access toggle.
- 1 Accept the TestFlight invite on the device you’ll type on.
- 2 Open the TestFlight app → tap **Install** next to iSureType.
- 3 Launch the app once so the onboarding screen can register the keyboard extension with iOS.
- 4 iOS Settings → **General → Keyboard → Keyboards → Add New Keyboard** → pick iSureType.
- 5 Back on that row, tap iSureType → enable **Allow Full Access**. Full Access is what lets the keyboard read the shared clipboard and play key-click audio; nothing leaves your device either way.
- 6 In any app with a text field, long-press the globe icon on the system keyboard and pick iSureType.
