Google Health 5.07.2 already has the screens for three Fitbit Air features Google has not shipped.

Marko Maslakovic at Gadgets & Wearables dug through the app and found Blood Pressure Trends, Insulin Resistance Trends and Sleep Breathing Quality built out well past a feature flag. The first two carry their own routes, onboarding components and chart handling. They have empty states written for them as well, with one message for when there is no blood pressure trend data and a separate one for when there is no insulin resistance trend data.

The app sorts Sleep Breathing Quality into four levels, HIGH, MEDIUM, LOW and VERY_LOW, and Google has never described it in those terms in public. What it had said was that you would get a daily view of how much of your night you spent breathing well, followed by a longer monthly read. The app goes further than that. It carries coaching lines to sit alongside the result, one about sleeping on your back and another about having a drink too close to bedtime. Sleep Breathing Quality is not going to be another number in the Health tab.

Its device comparison page puts all three features in September 2026. The Fitbit Air product page still says the Health Guardian suite is coming soon. Both pages are live right now, which is Google arguing with itself about the date.

This matters more here than it would on a watch, because the Air has no screen. It went on sale on May 7 at $99.99, and nearly everything it does, it does through the phone. An owner waiting on insulin resistance trends is not waiting for firmware to reach a band on their wrist. They are waiting for Google to switch something on in an app they already have installed.

In August Google put a screen-equipped tracker through two Pixel 11 ads while selling nothing that looked like it.

A teardown is code, not a promise, and Gadgets & Wearables says so in its own piece. Features found this way get renamed, delayed and dropped, and blood pressure trending in particular is the kind of claim that draws regulators before it draws buyers. What sits in the app today is the setup flow, the charts and the copy for an empty screen, and by the teardown’s reading none of it looks like it is waiting on a future build.

Google named all three features when the Air went on sale in May. Four months on, the screens have arrived and the features have not.
