Who Needs a Smartwatch When You Can Have a Smartring?
Fitness trackers range from complex smartwatches to subtle wrist bands or clip-ons. Motiv ($199) does one better with its fitness ring. Available in seven sizes and either rose gold or slate grey, the titanium-wrapped ring pops onto a finger or thumb where it will measure heart rate, activity, sleep, steps, calories burned and more. A double twist of the ring auto-syncs it with your iPhone (Android is on the way) and you can even swim with the device that has 165-foot waterproofing.
