Tally Counter for Smart Watch and Headset

I've been trying to come up with an app for my Sony Smart Wireless Headset pro, and like I mentioned in my Ignite talk, I often get new ideas when I swim. This time, however, it was quite literal. I was handing my pass to the clerk at the counter, and he clicked on his tally counter to keep track of how many people went swimming that day. That is perfect for the headset! It just needs one button to operate, which the headset has a big one in front, somewhere to show the counter, which the headset can do on its display.

After the made the app on the headset I decided to put it on the watch as well. Initially I used the same style, but then I realized the watch has a color screen, so I added some gradients to give it a background that looks like the dial on an odometer.

I did some user testing: gave the watch and headset to my husband to try. The headset was great, he said, because the button gave him tactile feedback, so he knew he clicked successfully without looking. Maybe I could add vibration to the watch? It was a really great idea. Besides giving tactile feedback, the vibration made a little buzz, and it happens to emulate the sound of a real tally counter. It was really satisfactory to tap on the watch and hear the count go up.
