About this app

Timecode math for editors, assistant editors, DITs, colorists and post-production crews. Add, subtract, multiply and divide timecode at your project's frame rate, convert between timecode, frames and seconds, and change frame rate without losing the duration.

Timecode Calculator Pro is free to download. The calculator, all ten frame rates, history and copy and paste are free. Pro is an optional one-time in-app purchase of $1.99 that adds four tools for longer workflows. No subscription.
