One place for everything you track

The Fitbit Air keeps your data in Google's world, and it doesn't write to Apple Health on its own. Airlift bridges the gap.

😴

Full sleep stages

Awake, light, deep and REM — mapped faithfully, plus time in bed.

💓

Your vitals

Heart rate, resting HR, HRV, SpO₂ and respiratory rate.

🚶

Activity

Steps and distance, on the days your band recorded them.

✅

Checked first

Every reading is compared to what Apple Health already has. Auto-import the clean ones, or review everything yourself.

🔒

Private by design

Runs entirely on your iPhone. Your Google sign-in stays in the Keychain. No analytics, no ads, no server.

🌎

Travel-correct

A night logged in one time zone lands on the right day, wherever you sync.

Why the wait? Google's built-in-public Health API is what makes faithful Fitbit sleep stages possible — but it's pre-release, and shipping it to everyone needs Google's restricted-scope security assessment. Airlift is ready and waiting; the waitlist is how you'll hear the moment that clears.
