Yeah, I had a Withings semismart watch, one of their cheaper models without a screen. It integrated a pedometer, and had a dial had that would show steps taken, it moved from 0 to 100% of your goal. One had to pair it to the Withings Android app to set not just the goal for number of steps/day, but even for setting the time. I sold it after a few months, realizing how much I missed a second hand and a glow-in-the-dark face. Also, the app had a ton of telemetry going back to Withings. Building your own you would be in full control of the data.
