Clap is an iPhone film-slate app that uses the iPhone Duo’s hinge to mark a take, log its timecode, and prepare the next slate.

Field notes

For Duo models, the phone’s halves act as sticks; on other iPhones, users tap the on-screen sticks. The page describes a one-frame flash timed to rates from 23.976 to 60 fps, plus a one-frame 1 kHz tone option and a warning about Bluetooth audio delay. The log supports keeper and NG marks, notes, setup numbering, and PDF or CSV camera reports; the site says productions remain on-device.
