It works !
The app works like it should, I get nudged before my partner realises I have been snoring. It’s missing a few features to make this perfect, most notably a toggle to turn off the audible alarm. I use the app with silent mode set on the watch as vibrations all that’s necessary to get me to stop snoring (and a ding-a-ling during the night would bother others). The other feature request would be a summary of the previous night: number of times the snore alarm was triggered for example [edit] I’ve found a bug, if the watch drops into battery saving mode then the app becomes unresponsive and you have to restart the watch to use it the next night.
