Is it technically possible to develop a js app that does this?
Yes , you could build a clock where pressing BTN1 would start and stop counting steps if you wanted to. The Run App works like this already. You could copy that as a starting point. Or you could count steps using the Bangle.on('step',x) event BUT only count steps when you had not put your app into pause mode.
