Fitbit Air trades a watch screen for a smaller health tracker

Google introduced Fitbit Air on 7 May as a small, screenless wearable compatible with Android and iOS. Orders opened at $99.99, including a three-month Google Health Premium trial. Instead of showing notifications or charts on the wrist, the device sends activity and health information to the Google Health app.

Google specifies up to a week of battery life and a five-minute charge providing a day of power under its stated conditions. The tracker records measures including heart rate and sleep, with automatic workout detection. Some health features have separate eligibility and regional restrictions. The design choice is clear even before judging an algorithm: removing the screen makes the phone responsible for reviewing information and changes how often a user interacts with the wearable.
