If a wrist wearable to track your workout is homemade videos from sex vacationa bit too conspicuous for your taste, a solution might be here: just wrap Motiv around your finger.

The smart ring packs just about everything you could hope for in a fitness tracker into a tiny circular package — minus a display, of course. But if you're looking for a compact, discrete wearable, who needs a screen?

The titanium ring, which comes in either slate gray or rose gold in seven sizes, uses three sensors (an optical heart rate sensor, a 3-axis accelerometer and a smart LED sensor) to keep track of its wearer's activity and heart rate at all times. Along with standard fit tracking measures like steps and calories burned, its heart rate sensor gives additional insight to keep up with resting and active heart rate.

Motiv is waterproof up to five meters, so there's no worries about daily wear or even taking it in the pool for a swim. Like most other wearables, its companion app provides personalized feedback and wellness goals for activities and sleep alike. Motiv's battery can last between three to five days, depending on use.

While there are other smart rings out on the market, most are focused on notifications, acting as extensions of a smartphone instead of providing any additional function. Notably, BioRing, a similar wearable that billed itself on IndieGoGo as a "personal trainer on your finger," had its fundraising campaign closed by the site after being outed as a scam.

For now, it looks like Motiv is the most advanced ring out there — unless, of course, someone has managed to recreate the One Ring from Lord of the Rings somehow. Even so, just imagine how useful it would've been if Frodo could've been tracking his steps on the whole trip to Mount Doom. Sauron really dropped the ball there.

Motiv is available for preorder now for $199. The rings will ship for iOS this spring, with Android-enabled units following in the summer.
