Does HoldSay work on iPhone Duo?
According to its developer, yes. FoldHunt's editor hasn't checked HoldSay on iPhone Duo yet, so it's listed as a claim.
- Developer claimedOran Xu posted a video of HoldSay on a rendered iPhone Duo (@xl_oran on X). The HoldSay account said the App Store screenshots were uploaded and linked that video (@holdsay on X). The App Store version dated 2026-10-05 (id 6777466153) describes snapping slides into a transcript. Those release notes do not mention the Duo.

Stood half-folded like a small laptop, the camera and the SLIDE button stay on the upright half, aimed at the slide, and the live transcript runs on the half lying flat.

Notes beside the camera
Open, the day's notes, each with its timestamp, run down the left half and the camera, still aimed at the slide, sits on the right.
