## What is VO2Cue?

Stop watching the clock. Start owning every interval.
VO2Cue is an eyes-free 4×4 interval coach built for Apple Watch, swimming, running, cycling, rowing, treadmill sessions, and gym cardio. Clear haptics, tones, voice cues, and large visual timers keep you moving without constantly checking a screen.
THE CLASSIC NORWEGIAN 4×4
Start immediately with a proven 35-minute structure:
• 10-minute warm-up
• Four 4-minute hard intervals
• 3-minute active recoveries
• Optional cooldown  
VO2Cue tells you when to push, recover, and finish—so you can focus on the effort instead of doing timer math.
YOUR WORKOUT, YOUR WAY
Create and save custom workout profiles with control over:
• Warm-up duration
• Work and recovery intervals
• Number of rounds
• Countdown length
• Optional cooldown
• Activity type
• Haptics, tones, and voice cues
• Halfway notifications
• Custom words such as Sprint, Hard, Recover, Easy, or Jog  
EYES-FREE APPLE WATCH COACHING
Run the complete workout from your wrist. Start, pause, resume, skip, or end a session directly from Apple Watch.
Distinct haptic cues help you recognize countdowns and phase changes without interrupting your stride, stroke, or rhythm. When Health access is permitted, VO2Cue can also display live heart rate during a Watch workout.
BUILT FOR REAL TRAINING
VO2Cue works anywhere watching a timer is inconvenient:
• In the pool
• On the treadmill
• During outdoor runs and rides
• On a rowing machine
• In a busy gym
• During any interval-based cardio session  
CLEAR WHEN THE EFFORT GETS HARD
Large timers, high-contrast phase states, progress indicators, and unmistakable labels make every workout easy to follow. Important changes are never communicated by color alone.
TRACK YOUR MOMENTUM
Review completed sessions, recent workouts, total active minutes, and workout duration in your local history.
Optionally save completed workouts to Apple Health. If Health access is unavailable or declined, the timer and local history continue to work normally.
PRIVATE BY DEFAULT
Your training belongs to you.
• No account required
• No ads
• No third-party tracking
• No analytics SDK
• No backend
• Profiles and history stay on your devices
• Health data is managed through Apple Health permissions  
ACCESSIBLE BY DESIGN
VO2Cue includes VoiceOver-friendly controls, Dynamic Type support, high-contrast layouts, reduced-motion support, and audio, haptic, and visual alternatives for important workout events.
Set your workout, start the timer, and let VO2Cue guide the rest.
