VO2max app

VO2max app is the first app able to quantify your cardiorespiratory fitness level by using only your phones camera and motion sensor, without requiring any specific exercise protocol.

HOW DOES IT WORK?
State of the art research showed that combining anthropometric data (i.e. your height, weight, age and sex), together with your physical activity level and heart rate can provide accurate cardiorespiratory fitness estimation, without the need for laboratory tests.

VO2max app can acquire your heart rate and physical activity levels with high accuracy, and combine these parameters to provide you with a key indicator of your physical condition, your cardiorespiratory fitness level or VO2max.

FEATURES
- VO2max estimation
- PPG based heart rate measurement using the phones camera
- Energy expenditure estimation using state of the art methods combining activity levels and activity-specific models
- Step counter
- Reports confidence of the estimated VO2max
- Data export (csv sent by email or via Dropbox)
- History, weekly and monthly summaries, moving averages, best records and other stats
- Manual activities can be added in case you dont carry your phone for your workout
- Data backup and synch on multiple devices
- Integrates with the Health app (writes heart rate to the Health app after each recording)

VO2max app requires an iphone 5S or later

VO2max categories (e.g. poor, good, excellent, etc.) are derived from Jackson et al. ACSM.
