Qalo announces screenless SL-1 health band that pairs with its smart ring

Gizmodo reports that Qalo’s subscription-free SL-1 band tracks sleep, heart rate, movement and other health data. It works on its own or alongside the SR-2 Smart Ring, with both devices contributing to the same health profile. Each retails for $200. Qalo says the band lasts over 12 days on a charge, though Gizmodo notes that claim still needs testing.
