Haven't been able to get a recording while I sleep. Recording seems to just stop when screen turns off. Since the hardware doesn't seem to store data it makes it basically useless. I have granted the app all sorts of permissions to run in background, be exempt from do not disturb, etc. Nothing works.

No lines in graph with Android 13, 15, and 16 for continuous monitoring. I have to create a PDF to send to my email to view results, which takes 5 minutes or more for it to produce. Doesn't look like they update this app anymore, may be abandoned. Alarm works OK for continuous monitoring.

poor instructions for blue tooth. actually non existent. But I was in IT for 30+ years so it really wasn't hard to figure out. No reason these folks need all your info to set up an account. Really should be no need to set up an account. paired the device. did not work with their app. d
