Burst is the interval timer built for athletes who actually train.

No bloated menus. No ads interrupting your sets. Just a fast, flexible timer that handles complex workouts (pyramids, random cues, variable EMOMs) while you focus on hitting hard.

🎯 What makes Burst different

- Smart beep modes most timers don't have
- Pyramids: auto-scaling intervals (10-20-30-40...)
- Random cues: unpredictable beeps for reaction drills (bag work, shadowboxing)
- Variable EMOM: progressive speeds (Luc Léger, VAMEVAL, shuttle tests)

- No ads during your workout
You'll never get interrupted mid-round. Ads only appear before you start or after you finish.

- Built for real sessions, not just "20/10 Tabata"
Combat rounds (3×5:00), long VO2 intervals (4×4 Norwegian), complex MetCons, cardio tests... Burst handles it.

- Your timers, your way
Tap a preset, adjust it, save as favorite. Next time: one tap to start. No rebuilding sessions from scratch.

🔊 Clear audio cues you can hear

- Distinct sounds for start, work, rest, transitions
- Optional "last 10 seconds" warning
- Works perfectly with music or podcast playing
