A gadget that never requires charging might sound like a pipe dream, but if it is, the Misfit Flash is that dream come true. Powered by a coin cell battery that lasts up to six months, this sleek tracker uses a 3-axis accelerometer to monitor your movement and sleep, measuring steps, calories burned, distance, sleep quality, and duration. It transfers all this data to your phone via Bluetooth, providing you with updates via a halo of lights on the front that show your progress toward your goal while also telling the time. It's also waterproof, wearable in several different ways, and, oh yeah, it's less than half what most fitness trackers cost.
At this point, you might have some trouble being bothered with yet another wearable fitness tracker — they're ubiquitous, with different options popping up nearly every other month. So what makes the Spire Health Tracker any different from the herd? For starters, it's not just about tracking your movement and sleep (though it definitely does that). The Spire focuses mainly on tracking your breathing, giving you real-time updates on your mood to help keep your psyche in check. Add on the fact that it looks great, charges wirelessly on its gorgeously-designed pedestal, and has a beautiful, intuitive app, and you get a tracker that's worth a second glance.
Given our newfound love of sensors to track everything from our movements to our sleep, it was only a matter of time before we started tracking even the more mundane aspects of life — like brushing our teeth. The Oral-B Smart Toothbrush lets you do exactly that, hooking up with your phone over Bluetooth 4.0 to let you keep track of your brushing habits, and brush more efficiently, as the app will tell you if you used too much pressure and lets you setup customized modes, timers, and routines, making sure you get the most out of each session, while keeping you entertained while you brush.
