SpeedClock isn't optimized for iPhone Duo yet: version 12.2 (Oct 30, 2021) predates the iOS 27 SDK, so it runs letterboxed. Checked automatically on Nov 11, 2026.
How the status was checked
- Automatic check
- Every day, from Apple's App Store data: the version, its date, and whether the listing has screenshots made for the Duo.
- Duo screenshots
- None on the current version.
- Hand test
- Not tested on a real iPhone Duo yet. A hand test covers five poses: cover, open, laptop, book and tent. How we test
