It's the ring that motivates you to fitness.

The Motiv ring is just that a ring, however it has many features associated with much bigger devices that you'd expect to wear on your wrist. It counts steps and activity, measures your heart rate (well pulse rate using an optical system on the inner section of the ring) and sleep.

Here's everything it tracks

• Active Minutes
• Resting Heart Rate
• Activity Types
• Calories Burned
• Activity Intensity
• Steps
• Distance
• Sleep Duration

The ring is made from Titanium and comes in black, silver and rose gold and US sizes from 6 to 12. Remarkably, there's battery inside that can last for a couple of days and it charges in about 90 minutes (it comes with a USB charger that magnetically pulls the ring into the correct charging position so the contacts align).

There's a companion app (Android and iOS) that has all the display functions as the ring just has an RGB LED on the outside of the ring under a transparent strip.

It works with Apple Health and Google Fit and also Alexa.

The app has some Lab features, like take a picture of your hand next to a dime and it will estimate your ring size (which in future may mean you don't need to order the ring sizing kit). There's also a security feature where the ring measures your step cadence and then it can automatically be used to unlock apps etc.

Your achievements can be shared with friends on social media and with your inner circle (other Motiv users that you add). There's also a FindMyiPhone feature that is activated by twirling the ring around your finder.

One glaring thing missing is FindMyMotiv, if you lose the ring, there's no way to locate it. It would be really useful to put the ring into "lost mode" where the LED and maybe heart rate sensor is turned on, so it would be visible if dropped (unfortunately that's what occurred while playing sports in a park, so it was impossible to locate, if it flashed, it would have at least been possible to spot it as the sun went down).

People will know that quantified-self is something close to my heart and the Motiv definitely had the best sleep tracking of all the devices I've owned. It's also small and would suit people who don't want to wear bulky trackers that go on your wrist (so often asked "why are you wearing 2 watches?"), though as someone who's never worn a ring before, it's definitely noticeable wearing it (and more noticeable when you've lost it and it's no longer on your finger).

Having worn it for about 6 months, it did get a bit of a battering and there were some scratches and the black finish showed the titanium underneath, but a great inconspicuous fitness tracker.

It's recommended to purchase a Motiv ring sizing set that costs £99.99 (which is offset again the cost of the ring itself when that is purchased). The ring costs £199.99 (i.e. if you know your ring size, it's possible to just purchase the ring, or order the ring sizing set first and the cost of that will be taken off the ring when that's ordered).
