Google Fitbit Air Obsidian with integrated GPS

Google Fitbit Air Obsidian

The Fitbit Air is a screenless activity tracker : it features comprehensive health sensors on the wrist, but all data is accessed through the Google Health app on your phone. Weighing only 5.2g without the strap , it’s so lightweight you’ll forget you’re wearing it. It’s the choice for those who want continuous health, sleep, and activity monitoring without a screen to manage or a battery to charge every day. The downside is clear: you won’t see the time, steps, or anything else on your wrist.

Screenless: what changes in real-world use and what do you gain in return?

The lack of a screen directly impacts usability: you can never look at your wrist to see your steps, time, or notifications—you can access all of that by opening the Google Health app on your phone whenever you want. On the other hand, the tracker is 8.3 mm thick and weighs 5.2 g , values ​​achieved precisely because there is no screen or the larger battery capacity that a larger battery would require. The result is a device you can wear day and night without feeling its presence, even while you sleep. The bracelet is made of fabric and polyurethane, not silicone: the touch is softer and more breathable for prolonged or nighttime use, although cleaning it is different from that of typical rubber bracelets, as the fabric can absorb moisture over time.

Sensors that continuously monitor your health without you having to do anything.

Optical heart rate, SpO2 (blood oxygen saturation), skin temperature, sleep tracking, and stress levels work automatically 24 hours a day, without you having to activate anything. The Google Health app collects all this data and presents it organized by day and trends. Things to know: basic recording functions require nothing more than the app itself, but personalized AI coaching and advanced sleep and stress analysis are available through a paid Google Health Premium subscription, sold separately. If you only want to see your raw data, the free version is sufficient. The integrated GPS records running or walking routes without needing to carry your phone, useful for occasional outings where you want to know the distance and route.

7 days of battery life and water resistance so you don’t have to think about it.

Up to 7 days on a single charge is enough to use it all week, including nights of sleep monitoring, without touching the cable. When it’s time to charge, it takes approximately 1.3 hours. As for water, the 5 ATM resistance is equivalent to 50 meters of depth: you can swim in a pool, shower, and exercise in the rain without taking it off. The 7 days corresponds to the value under standard conditions; if you use the GPS intensively on each outing, the actual battery life will be less.
