Google Kills the Fitbit Brand, Rebirths It as $99 AI Health Coach

Google just pulled the plug on the Fitbit brand and the entire idea of a fitness tracker with a screen. In its place: the Fitbit Air, a $99 band that looks like a Whoop clone but hides a much bigger play. The company is betting that a screenless sensor plus Google’s AI models can turn raw biometrics into a personal health coach that actually changes behavior. Pre-orders opened today, with shipping slated for late May.

The Air is a pebble-shaped module that slides into fabric or silicone bands and carries the standard health-sensor stack: optical heart-rate, accelerometer/gyro, SpO2, skin temp. Google admits the heart-rate sensor is a step down from the Pixel Watch 8’s, so HIIT junkies may see drift. Battery life clocks in at “up to 7 days” and the whole thing is water-resistant to 50 m. No display, no buttons, no haptics, just a single LED that blinks for pairing.

According to Google’s briefing, 62 % of Fitbit owners already check their stats on the phone app instead of the watch face. By removing the display Google shaved $60 off BoM cost, doubled battery life, and, more importantly, forced users into the new Google Health app where generative AI can surface insights instead of raw numbers. The company calls it “ambient tracking, active coaching.”

The real product is the software layer. Gemini Nano runs locally to detect workout starts, sleep stages, and HRV anomalies; the heavier Gemini Pro models in the cloud spit out daily “Readiness” and “Stress” scores plus conversational nudges like “Your HRV tanked after last night’s pizza, maybe swap today’s run for yoga.” Google says the coach will remain free for basic metrics, but advanced “AI protocols” (think migraine-risk prediction, fertility windows) sit behind a $7.99/mo Fitbit Premium tier.

Whoop suddenly faces a direct clone at one-third the price and without a required subscription. Oura’s Gen-4 ring still wins on style and medical-grade temp sensors, but can’t match Google’s AI smarts or Play-store ecosystem. Apple Watch remains the do-everything king, yet its $399 entry fee and daily-charge cadence look excessive next to a week-long $99 band. Expect price cuts and new bundles from all three within months.

Fitbit’s old app sunsets at year-end. The new Google Health app aggregates Air data alongside Pixel Watch, Nest cameras (for fall detection), and soon, third-party Bluetooth LE devices. A new “Health Timeline” card stacks events chronologically so a user sees that elevated resting heart rate coincided with a spike in household air pollution captured by Nest. It’s the clearest sign yet that Google wants to own the entire health-data funnel, not just the wrist.

Data lives on Google’s health-specific cloud, siloed from ad profiles, and can be deleted account-wide in one tap. Still, the AI coach is not FDA-cleared; phrases like “may reduce risk of hypertension” carry an asterisk linking to a disclaimer. EU users get an on-device toggle to keep all processing local, cutting cloud features but sidestepping GDPR headaches. The free tier expires after 90 days unless you link a Pixel phone, a not-so-subtle nudge into Google’s hardware family.

Google execs hinted that the Air’s sensor pod is “module-agnostic,” meaning future versions could swap in ECG, blood pressure, or even non-invasive glucose sensors once they clear regulators. A developer SDK drops in July, letting third-party apps pipe raw data into their own models. If adoption hits even a fraction of Chromecast’s scale, every health startup suddenly has a $99 Trojan horse on millions of wrists.
