If you like small and cute wearables, it about time we put a ring on it. Smart rings come with some sort of tech built into them so that they can track your sleep, activity, pulse rate and more. Most of them can connect to your smartphone via Bluetooth. Unlike smartwatches and fitness bands that can be tightened and loosened to fit your wrist, smart rings are a tad difficult. They usually come with sizing kits to improve fitting. Smart rings come in cool designs with like fitness trackers, NSC chips, SOS buttons and more. As they do not have a screen, they do not require frequent charging. You can pick a variety of options available in the market today – Keydex NFC Multi-Function Ring, the Oura Ring, the Motiv Smart Fitness Ring and more.
