So you’ve got that 10,000-steps-a-day thing down, and you’re ready for the next level.

What if your tracker told you in real time how to fix your stride or critiqued your swimming stroke or boxing technique?

That’s the idea behind Moov, a wristwatch-sized gadget that its founders refer to as a personal coach at a tracker price.

It uses artificial intelligence to analyze the way a wearer runs, swims, lifts weights, or cardio boxes, the founders said.

Motion sensors track the body’s form, and the device syncs with a smartphone app to provide feedback and coaching.

In the last few years, fitness trackers have become nearly ubiquitous. Samsung and Sony recently announced they are entering the market, competing with the likes of FitBit and JawBone – and plenty of cheaper pedometers.

But for one of Moov’s founders, Meng Li, that accounting just wasn’t motivating her. She had runner’s knees and was in pain. “I realized I didn’t know how I run. We started building around that,” she said.

She and her two partners, Nikola Hu and Tony Yuan, figured many other people could work out more efficiently and with better form – and would like a constant stream of data. Seven years ago, they started working on their idea.

Moov, based in Mountain View, Calif., recently began a campaign hoping to raise $40,000 to start production and send out devices in the summer. There was no prototype to try, but two of the founders showed one off in a video interview.

Hu, a former Apple and “Halo” game engineer, strapped one on his ankle and started to run in place. The device told him how to change his pace and his landing (“Lean forward and land mid-foot to soften your impact.”). He then put it on his arm to cardio-box, and the “coach” suggested his elbow was too low in his punches.
