Folego

Fôlego reads the VO2 Max your Apple Watch already estimates automatically — during outdoor walks or runs — and shows your cardiorespiratory fitness band right on your watch, in a half-circle gauge that shares the same visual language as the native UV Index and Air Quality complications.

HOW IT WORKS No sign-up, no login, nothing to type in. Fôlego reads three pieces of information that already exist in the Health app — VO2 Max, date of birth, and biological sex — and automatically calculates which of 6 bands (from Very Low to Superior) your cardio fitness falls into, using the same reference standard as the American College of Sports Medicine guidelines.

ON YOUR WATCH • A Summary screen with the gauge and your current band • A history chart of the last several months • Complications for analog and digital watch faces (Modular, Infograph, Compass, and more), across circular, corner, rectangular, and inline families • Updates on its own whenever Health logs a new estimate

PRIVACY Health access is read-only — Fôlego never writes or modifies anything. There's no account and no server: everything it calculates stays on your own iPhone and Apple Watch. No analytics, no tracking, no ads.

The iPhone app exists only to grant Health permission — Fôlego is, first and foremost, an Apple Watch app.

Requires Apple Watch Series 4 or later (latest watchOS) and at least one VO2 Max estimate already recorded in Health.
