it doesn't measure vo2max at all. it does need GPS data for an eligible activity (>20 minute outdoor runs/walks/hikes) because the estimate it'll spit out is reliant on some data like distance, pace and elevation that is derived from GPS (and other data points, namely heart-rate). none of that stuff requires a data connection
