TC Calc is a fast, native timecode calculator built for film, television, and video production. Whether you're an editor, assistant editor, script supervisor, producer, or post supervisor, TC Calc handles frame-accurate arithmetic directly on your iPhone or iPad.
Add, subtract, multiply, and divide timecode values. Switch instantly between 23.976, 24, 25, 29.97 NDF/DF, 30, 48, 50, 59.94 NDF/DF, and 60 fps. Drop-frame math is handled precisely. Toggle between standard timecode and raw frame entry - mix and match within the same calculation.
Every committed operation is tracked on a running tape. Share the full tape as plain text via any app on your device - Slack, Messages, Notes, email, AirDrop.
Attach a Magic Keyboard to your iPad and use the numeric and operator keys directly. Undo the last entry, or undo a full clear to bring back the entire tape.
Fast, correct timecode arithmetic.
