Does not have a simple respect Do Not Distrub setting. It's insane that the app doesn't align with the phones DND setting. Cannot wear it to bed to track sleep if it constant vibrates to messages and emails. App is really lacking. Take pebble as an example do what they were doing 5+ years ago! No option to flip the watch face to wear on the other wrist direct. No digital clock feature for behind the analog face for hybrids.
