Buy Now $199 Motiv is a waterproof fitness and sleep tracker that’s been so cleverly hidden inside a handsome Titanium ring you half expect Q to show up to demonstrate how it works. (James, pay attention!) But since he’s not here, it uses an optical heart rate sensor and 3-axis accelerometer to measure everything from steps, active minutes, and calories burned, to heart rate, distance traveled, and how many hours you slept last night. The answer, of course: “not enough.” The ring’s wee Li-Ion battery runs for 3-5 days on a single 90-minute charge. A magnetic USB keychain charger is also included so there’s still something you can forget and/or misplace. While some might see their wedding band as a reason to stop working out, the Motiv — as the name might suggest — is actually designed to get you fired up. The ring uses your resting heart rate from the previous night to adjust your goals for the day and if you complete 10 or more minutes of activity you’ll receive an “action card.” There’s no word on whether you can trade that card to your wife for an extra hour of sleep. Motiv does, however, sync via Bluetooth to a smartphone app where all the data appears in fancy charts and graphs, so you can use those to prove to her that you haven’t just been watching GoT for 3 hours. Rings come in both Slate Gray or Rose Gold (so you really could turn them into wedding bands) and to ensure they’re sized properly, you’ll receive a sizing set in the mail. They don’t ship until March, but you can pre-order today. Or, at least, as soon as you finish flipping those tires and climbing that rope wall. (Pre-order for March)
