Thanks for trying it. The notification actually doesn't control the sensor (green light) -- I think the timing was likely just a coincidence.

That said, we haven't had a lot of people with Gear Lives test the app yet, so it's always possible you've stumbled on some novel bug that only appears on certain hardware. Wouldn't be the first time. :)

If that behavior is reproducible, can you send a bug report to brandon@cardiogr.am?
