Atlas ($130 to preorder) may look like a typical fitness tracker — but it's not just a glorified pedometer. The waterproof (up to one meter), sweatproof wrist tech collects data about your workout and evaluates your form.
It counts reps and is smart enough to know what kind of activity you're doing. Atlas can tell when you're working on a bicep curl, and it knows when you've switched to alternating bicep curls. It even knows the difference between freestyle, breaststroke, and backstroke.
At launch, Atlas will support an iPhone app and a web dashboard, as well as compatibility with MapMyFItness, Fitocracy, and LoseIt.
