Fitness tracking with no screen: does it still work?

A screen changes what you do with a tracker. You check it mid-conversation, you chase a number, you charge it twice a day.

Take the screen away and the recording continues but the behaviour stops. The data arrives in the morning in the app instead of mid-run on your wrist.

For step counts and workout detection the underlying sensors are the same. What changes is how often you intervene — which, for most people, is the point.
