A growing group of fitness trackers is removing the screen rather than adding more smartwatch features. Garmin Cirqa, Google Fitbit Air, Polar Loop and Amazfit Helio Strap now join Whoop in collecting health and activity data without putting messages, scores or alerts on a user’s wrist.

The devices retain familiar sensors such as heart-rate monitors and accelerometers, then send their records to a phone app for later review. Their main promise is subtraction: users can track sleep, steps and workouts without reflexively checking notifications throughout the day. Some can also infer activities without requiring the wearer to tap a start button.

Artificial intelligence is moving the complexity into companion apps. Google’s Fitbit Air provides basic charts without a subscription, while conversational explanations require the $10-per-month Google Health Premium service. Other brands also present AI interpretation as an optional paid layer, making low-distraction hardware a route to recurring software revenue.

The format does not guarantee better health or a calmer relationship with technology. Users still need to open an app, interpret measurements and decide whether a subscription is worthwhile. It does, however, separate passive collection from immediate interruption—a practical alternative for people who want fitness records but not another screen demanding attention.
