Want all the benefits of a smart wearable, but can't face wearing a watch? The Motiv Ring (US$199, available to pre-order now) packs a heart-rate sensor, step tracker and sleep monitor into something you slip on your finger. Pop it on your chosen digit and it syncs to a companion app, which monitors when you’re active by reading your heart rate. Rather than prodding you to take 10,000 steps per day, the Ring pushes you towards 150 active minutes a week, which encourages more than just getting off the bus one stop earlier. We like the little extras featured on the Ring: you get two USB magnetic chargers in the box, which are small enough to keep on your keyring, while Motiv has also designed its own battery tech to fit into the curved design.
