Why in the world would this app send a notification through at 3:15am? I was sound asleep. I get a notification with the 1st visible line saying "you're doing well!" I didn't open it to see the full message, but when it hit me from my dead sleep that it wasn't an emergency from my family at 3am, I was furious because here on Sunday morning, my off day, at 3:15, I was awakened by my cpap app. I fixed it by turning my app notif off. But from a cpap app I shouldn't have to do that. Ridiculous
