Flextimer: Describe Timers

Flextimer helps you build custom timers for workouts, interval training, focus sessions, breathing exercises, presentations, routines, and more.

Design sessions with ordered steps, repeating rounds, labels, and colors. Add cues to any timer step for additional sounds, vibration, color transitions, or countdowns. Review total time, time by color, cue details, and progress behavior before you start a session. Easily fit every part of your session, from prep and work to breaks and cooldowns.

Prefer to skip the setup? Describe your timer in plain words and Flextimer builds it for you to review, then edit or save.
