PEAKVO2 vs VO2 Max Pro: Track It or Train It?
Run these workouts on your iPhone, or hands-free on Apple Watch. Get PEAKVO2 VO2 Max Pro and PEAKVO2 are not really competitors: one tracks your VO2 max, the other trains it. VO2 Max Pro reads your VO2 max from Apple Health and shows your fitness age, trends, and age percentile benchmarks. PEAKVO2 runs the guided protocols that raise your VO2 max and includes built-in field tests. Use VO2 Max Pro to watch the number; use PEAKVO2 to move it.
A lot of "VO2 max apps" fall into one of two camps: trackers that display and interpret the number your Apple Watch already estimates, and trainers that give you the workouts to improve it. VO2 Max Pro is a tracker. PEAKVO2 is a trainer. That is the whole comparison, and it is why they pair well rather than replace each other.

What VO2 Max Pro Is
VO2 Max Pro is a VO2 max tracking app. It connects to Apple Health, reads the VO2 max your Apple Watch estimates, and turns it into insight: instant notifications when new data syncs, trend and progress charts, a fitness or biological age read on what your number means, and benchmarks that show where your VO2 max falls by age and gender, including a percentile badge and interactive charts you can switch between male and female ranges. It runs privately, with data staying on your device. It does not run workouts; its job is to help you understand and monitor the number.
What PEAKVO2 Is
PEAKVO2 is an interval training app for iPhone and Apple Watch, built around raising VO2 max. It runs 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 heart rate zones. 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, not only from your watch's passive estimate. It is a training app, not a testing service.
The Core Difference: A Dashboard vs a Gym
VO2 Max Pro is a dashboard. It is very good at showing you the number, what it means for your fitness age, and how you compare to others your age, and it does that better than a training app does, because analytics is its entire focus. But a dashboard cannot raise your VO2 max; it can only report it.
PEAKVO2 is the training that changes what the dashboard shows. The protocols it runs, especially the Norwegian 4x4, are the ones proven to raise VO2 max, and its built-in field tests let you check progress directly. If you want to understand and monitor your VO2 max, VO2 Max Pro is a clean, free way to do it. If you want that number to go up, you need the training, which is what PEAKVO2 is for. For context on what the number means, see our guide to a good VO2 max by age.
Who Each One Is For
- Choose VO2 Max Pro if you want to monitor your VO2 max, see your fitness age, and compare yourself to age and gender benchmarks, and you are happy relying on your Apple Watch to generate the number.
- Choose PEAKVO2 if you want to raise your VO2 max with guided interval protocols and test it directly with built-in beep and Cooper tests, on iPhone and Apple Watch.
- Use both for the full loop: PEAKVO2 to train and test, VO2 Max Pro to watch the trend and benchmark it. They complement each other cleanly.
