Film clapperboard app: slate with a timed clap sound, take log and tail slate
A clapperboard app for your phone: a full screen film slate with a clap sound timed to the moment the sticks meet, so sound and picture line up in the edit.
Fill in the production, roll, scene and take, then tap or swipe the sticks. The clap sound, a short screen flash and the shut sticks land together. The app measures your phone's own audio delay and corrects for it, and a sync offset lets you fine tune it after a test clap.
Features
- Full screen slate with production, roll, scene, take, director, camera and date
- Clap sound, 1 kHz sync beep, or both, timed to the sticks
- Corrects your phone's audio delay, with a sync offset setting
- Take goes up by one after each clap, with Undo for a false clap
- Next setup and Next scene buttons that start again at take 1
- Tail slate: the board turns upside down for an end board
- Recents grouped by shoot day, with night shoots kept together: circle good takes, mark no good, add notes
- Optional INT/EXT, DAY/NIGHT, frame rate and sound roll fields
- Date styles: 2026-10-23, 23 OCT 26, 23/10/26 or 10/23/26
- Swipe down to clap, so a brush or a grip won't clap by accident
- Classic Black, Indie White and Wedding Soft looks free
- Works offline, no account
Pro
A one-time Pro unlock keeps every shoot day in Recents and shares the take log as a PDF take report for the editor or a CSV spreadsheet, a day at a time or all at once. It also adds Night Chrome, Amber Set and Forest Matte looks, a silent (MOS) clap, a time of day clock on the board (your phone's clock, not synced timecode), and slate images without the Clapperboard mark.
Pricing
Free: the slate, timed clap, take log for your latest two shoot days with marks and notes, tail slate and 3 looks. Clapperboard Pro is a one-time lifetime unlock. No subscription.
