Motiv
There are two main problems with modern fitness trackers: they constantly need to be charged, and they look obvious and ugly on your wrist.But a new device called the Motiv ring is solving both of those problems. The ring is designed to be worn on your hand 24 hours a day, and its charge lasts for up to five days. When it does need to be charged, it just sits on a small charger you can attach to your keychain.
The Motiv ring is a heart rate sensor, fitness tracker, and sleep tracker, and it's about the size of a wedding band. Motiv has been working on the ring for the past five years to make it as small and slim as possible while still counting your steps, tracking your runs, and helping you get a sound sleep.
The ring costs $199 and will begin shipping this summer. Here's how it works.
