Random 3 AM notifications are psychotic. Liven lets you set quiet hours and control exactly when pings arrive. No server tantrums. No sleep interruptions. Tested it myself across different time schedules. Works perfectly. For anyone in Australia tired of apps that think bedtime is optional, the liven app review in AU covers notification controls specifically. Users there confirm they finally sleep through the night without being woken up by mental health pings. Set your window once and forget about it.
