What VO2Max Training Is
VO2Max Training is a structured VO2 max app for iPhone and Apple Watch. You can browse research-backed protocols, the Norwegian 4x4, Tabata, Zone 2, and more, or build your own sessions with an interval builder. It supports live heart rate, starting and controlling workouts from Apple Watch, and a Lock Screen Live Activity, and it connects to Apple Health to track your VO2 max, weekly metrics, and training load over time, with AI-powered insights. It is free with a premium subscription at $4.99 per month or $49.99 per year. Its distinguishing strengths are Zone 2 in the same app and its analytics: training-load tracking and AI insights.
What PEAKVO2 Is
PEAKVO2 is an interval training app for iPhone and Apple Watch, built around VO2 max. It ships eight validated protocols, the Norwegian 4x4, Tabata, HIIT 30/30, Billat 30/30, Ronnestad 30/15, VO2 Max 3x3, VO2 Max 5x3, and Tempo Run, with full-screen color-coded phases, automatic transitions, a haptic tap at each switch, and the heart rate zones each protocol depends on, and it lets you build your own custom intervals too. It runs natively on Apple Watch with no phone needed, tracks your VO2 max trend over time, and includes built-in beep and Cooper field tests so you can measure your VO2 max directly. It is a training app, not a testing service. Its distinguishing strengths are its field tests, its wide set of named protocols, and its pricing, including a one-time lifetime unlock.
The Real Differences
Because the core is the same, and both let you build custom intervals, the decision is about a few specific things:
- Field tests. PEAKVO2 has built-in beep and Cooper tests, so you can estimate your VO2 max from a direct maximal effort. VO2Max Training tracks the number through Apple Health but does not advertise its own field tests. If you want to test, not just track, that favors PEAKVO2.
- Zone 2. VO2Max Training includes Zone 2 among its protocols. PEAKVO2 focuses its ready-made library on higher-intensity VO2 max protocols. If you want Zone 2 guided in the same app, that favors VO2Max Training.
- Analytics. VO2Max Training adds training-load metrics and AI insights on top of VO2 max tracking. PEAKVO2 focuses on running the protocols and tracking the trend. If deeper analytics matter, that favors VO2Max Training.
- Price. PEAKVO2 is cheaper and offers a lifetime unlock at $19.99; VO2Max Training is subscription-only at $4.99 per month or $49.99 per year. If you prefer to pay once, that favors PEAKVO2.
Who Each One Is For
- Choose PEAKVO2 if you want built-in beep and Cooper field tests, a wide set of named protocols with a custom builder alongside them, and cheaper pricing with a one-time lifetime option.
- Choose VO2Max Training if you want Zone 2 in the same app and training-load analytics with AI insights, and a subscription is fine.
- Either is a solid choice for the essentials, since both run the Norwegian 4x4 and Tabata on Apple Watch, both let you build custom intervals, and both track your VO2 max. Decide on the differences above.
