Google Fitbit Air Berry

Google Fitbit Air Berry Description

Google's smallest, lightest Fitbit tracker — a screenless clip-in core that pairs to the Google Health app for 24/7 health monitoring and AI-powered coaching. At 5.2g without the band, it's designed to disappear on the wrist while capturing continuous heart rate, SpO2, sleep, and skin temperature data around the clock. Berry colourway features a polished champagne gold stainless steel buckle.

• Design — screenless, 5.2g without band: No display to interact with or charge around; all data lives in the Google Health app. The tracker core slots into swappable textile bands, and the minimal footprint (34.9 × 17 × 8.3mm) means it's comfortable enough for full-time wear including overnight.
• Heart health — continuous HR, Afib detection, HRV, SpO2: Optical heart rate sensor runs 24/7 with resting heart rate, heart rate variability, and irregular heart rhythm (Afib) alerts; red and infrared sensors add blood oxygen (SpO2) monitoring — a meaningful sensor set for a £99/$99 device.
• Sleep tracking — stages, duration, skin temperature: Tracks light, deep, and REM sleep stages alongside sleep duration; the device temperature sensor surfaces skin temperature variation overnight, with trends shown in the Google Health app.
• AI coaching — Google Health Premium (3-month trial included): Personalised daily readiness scores, stress indicators, and habit coaching powered by Google Health AI; requires Premium subscription after the trial period.
• Battery — up to 7 days, fast charge in 5 minutes: Lithium-polymer cell rated to one week between charges (90 minutes for a full charge); 5 minutes on the USB-C cable gives a full day of use — practical for anyone who forgets to charge.
• Data storage — 7 days of minute-by-minute motion, heart rate at 2-second intervals: Detailed data is stored on-device and syncs over Bluetooth 5.0 within 30 feet; daily totals saved for the last 30 days.
• Water resistance — 50 metres: Suitable for swimming, showering, and everyday splashes; textile band should be dried after prolonged water exposure.
• Wrist fit — textile band, 130–210mm one-size (silicone options available separately): The included textile/polyurethane band covers most adult wrists in a single size; silicone small and large bands sold separately for those who prefer them.
• Compatibility — Android 11+ / iOS 16.4+, Google Account required: Works with iPhone and Android via the Google Health app; Bluetooth LE syncing, no Wi-Fi needed on the tracker itself.
• Sustainability — recycled housing, plastic-free packaging: Tracker body made from responsibly recycled polycarbonate and PBT plastics; packaging ships 100% plastic-free.
