Biological Age & VO2 Max
About

What's New in Drift
2.0.4
November 4, 2026
Settings now has a “More from Stationify” list — the other apps built by Drift's developer, with a one-tap install. Drift also points you at a sibling app in the two places it genuinely can't help: Kiito for the training that moves your VO₂ Max, and Sleep Talk for what actually happens during the sleep stages Drift reads. Both suggestions are dismissible for good, never appear on a first launch, and never stack on a rating request. As always, nothing about your health leaves this phone.
