## What is Flextimer?

More than a countdown. Flextimer is a flexible interval, round, and HIIT timer for workouts, focus, routines, and more — built your way. Design a session step by step, or just describe it in plain words and let AI create it for you to review, edit, and save.

Describe. Cue. Run.

What sets Flextimer apart is the combination: named steps and repeating rounds, cues for sounds, vibration, color changes, and countdowns, a clear Timer Summary, and AI that can build a timer for you. Fit every part of your session, from prep and work to breaks and cooldowns.

Use Flextimer for:
  • Workouts and interval training (HIIT, EMOM, Tabata)
  • Boxing, MMA, and round timers
  • Pomodoro and focus sessions
  • Meditation and breathing exercises
  • Presentation and speaking practice
  • Stretch breaks, chores, cooking, and daily routines
  • Structured sessions that need more than one countdown

Features:
  • Describe a timer in plain words and let AI build it for you (preview)
  • Flexible step and repeat-group timer design
  • Optional final-step skipping, useful for omitting final rest periods
  • Step cues for additional sounds, vibration, color transitions, countdowns, or in repeating intervals
  • Timer Summary with total time, time by color, cues, and progress behavior
  • Configurable run-screen controls for next step, total remaining time, skip, and restart
  • Custom progress tracking for steps or rounds
  • Saved custom timers and built-in starting points
