undercutf1 for Mac

undercut-f1

undercut-f1 is an open source F1 Live Timing client.

undercutf1 is a TUI application which uses UndercutF1.Data to show a Live Timing screen during sessions, and records the data for future session replays. F1 live broadcasts are usually delayed by some indeterminable amount (usually 30-60 seconds), so the TUI allows you to delay the data being displayed so that you can match up what you see on your screen to what you see on your TV.

The UndercutF1.Data library is provided to facilitate connectivity with the F1 Live Timing data stream, and handle all the processing of the incoming data. It also allows for "simulated" streams, where previously recorded data streams can be played back to allow for easy development/testing.

Feature Highlights: Timing Tower showing for each driver: Live sector times, with colouring for personal/overall fastest Last & Best Lap Current tyre Age of current tyre Interval to driver in front Gap to leader Gap between a selected driver and all other drivers (useful for monitoring pit windows) Pit Stop Strategy gives you at-a-glance information about all the drivers strategies Race Control messages including investigations, penalties, lap deletions, and weather Driver Tracker shows the position of selected drivers on a live track map Lap-by-lap Timing History to observe gaps over time Pause the session clock when you pause external video players (such as Kodi), so that your timing screen remains in sync with your feed. [!WARNING] Since the 2025 Dutch GP, the F1 Live Timing feed no longer freely publishes some of the data we need to provide all existing functionality. The following functionality is now only available to those who have an active F1 TV subscription:

• Driver Tracker (live position of each car is unavailable)
• DRS Indicator in Timing Screens
• Team/Drivers championship tables
• Pit Stop times (in box and in pitlane)

Importing a session after it finishes still fetches all the data, so all functionality is available if you use undercut-f1 after a race finishes. Linking your F1 TV account with undercut-f1 is as simple as running undercutf1 login before starting your session, and following the instructions displayed. See F1 TV Account Login for details.
