Ntrval Timer

Ntrval is an interval timer built for how people actually train — fast to set up, clear to read across the room, and flexible enough for everything from a quick Tabata to a full coached session.

Design a timer in seconds: set your work and rest intervals, rounds, colors, and sound cues, then hit start. Or build a complete workout from your own exercises and let Ntrval generate the timing for you.
