If you want to get fit, you should probably put a ring on your finger. Yes, a smart or intelligent ring. This applies to those who find fitness trackers in the form of watches, wrist bands and such other wearables too big, too visible, too uncomfortable and never matching their outfits. Shrinking a fitness tracker into a ring form is no small feat, yet the outcome is a sleek, ultralight titanium gadget that wirelessly syncs with an app to provide activities such as heart rate or sleep data with an aim of helping one set goals to improve their health. It can withstand the elements so it’s safe to wear even during swimming. Wearers have complained that they have had to remove the rechargeable gadget during workouts such as weight lifting.
