AI WORKOUT GENERATOR
Point your camera at a gym whiteboard or type your workout.
AI reads it and sets up the complete timer in seconds.
No programming. No fumbling. Just press go.
APPLE WATCH SYNC
Full timer on your wrist the moment you start.
See rounds, phases, and time remaining without touching your phone.
Haptic cues keep you on pace. Start and pause from your wrist.
REAL-TIME HEART RATE & CALORIES
Live BPM and active energy during every session via HealthKit.
Know exactly how hard you're working without leaving the timer.
5 PURPOSE-BUILT FORMATS
Not a generic countdown. Each format knows exactly what it's doing:
• For Time — race the clock, finish as fast as possible
• AMRAP — maximum rounds in a fixed window
• EMOM — new movement every minute, automatically
• Tabata — 20s work, 10s rest, 8 rounds, handled
• Custom — chain any combination into one session
No manual resets. No counting rounds in your head.
TimerFlex handles all of it.
