I’m in the final stretch. My legs are aching; I’m drenched in sweat. The finish line is near, I can feel it. My wrist buzzes. An email: Amazon finally shipped my order of Rice Krispies Treats cereal. I keep running. My wrist buzzes again. A calendar reminder, editorial meeting in one hour. I ignore it and keep going, pounding the treadmill below me with each step. Finally, my wrist buzzes again. This is the one I’ve been looking for — I’ve hit my goal of 20,000 steps for the day and the Samsung Gear Fit I’m wearing is proudly displaying a gold medal for doing so. I smack my hand on the kill switch and the treadmill slows to a stop.

This is the dream, a wearable device that tracks my fitness activity while providing smartwatch functionality. And it’s exactly what Samsung is pitching with its new $199 Gear Fit. The Fit combines the best of fitness tracking — step counting, heart rate monitoring, and real-time coaching — with smartwatch sensibilities. It’s an obvious idea, and others have tried this to a limited extent before, most notably Fitbit with its ill-fated Force, but nobody has done it well. Samsung promises that it has finally cracked it.

It’s just too bad that dreams don’t always line up with reality.
