LetterboxedChecked automatically

Voice-activated Recorder isn't optimized for iPhone Duo yet: version 3.0 (Nov 19, 2018) predates the iOS 27 SDK, so it runs letterboxed. Checked automatically on Nov 10, 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 postures: cover, open, laptop, book and tent. How we test

Apple hasn't published the date it started taking iOS 27 SDK builds; we use Sep 1, 2026, early on purpose, until it does.
