Why minimal trackers pair Fitbit Air with the Panther Eclipse

Both are integrated-case trackers built to disappear on the wrist. The Fitbit Air keeps the Fitbit health picture, the Panther Eclipse adds a screen-less stainless steel device with no subscription, 14 to 15 days of battery and HR, HRV, SpO2, temperature and blood pressure.

Smartlet holds both on one strap, each in its own position.
