## What is VO2 Max Helper?

VO2 Max Intervals turns interval training into something you actually stick with — real protocols, not just a countdown timer.

TRAIN WITH REAL PROTOCOLS
Choose from a library of interval sessions grounded in real training science:
- Norwegian 4x4 — the gold-standard VO2max protocol
- Billat 30/30 and 15/15 intermittent — high time-at-VO2max intervals
- Tabata — 20 seconds on, 10 off, all-out
- Micro-Bursts 30/15 — a cyclist favorite
- Long Intervals 5x5 — bigger aerobic volume
- Round-based combat sport timers: Boxing, Muay Thai, and MMA

BUILD YOUR OWN
Set your own warm-up, work interval, recovery, rounds, and cool-down, then save it for next time. As many custom protocols as you want.

TRAIN WITH REAL NUMBERS
- Connect any Bluetooth heart rate strap, or use your Apple Watch
- See your live heart rate during every round
- Look up your estimated heart rate training zones from your age
- Every session is logged automatically to your workout history

DESIGNED TO DISAPPEAR INTO YOUR WORKOUT
- Full-screen countdown with voice and audio cues for every phase change
- Live Activity on your Lock Screen, so you never have to unlock your phone mid-round
- Apple Health sync for completed workouts
- Light and dark themes
- English, French, German, and Sinhala language support

No account, no setup — open the app and start your interval.
