Personally paid for Niagara launcher as I find that to be the far superior launcher to any other I’ve tried. My second one is Symfonium, the most feature rich and well developed audio player.
What are yours?
The only paid app I’ve got is Sound Profile. Puts the phone on quiet (except for family) at night, or silent (with auto resume to normal) in meetings. It’s on my & spouse’s phones.
Idk about the meeting thing but do not disturb can do this already. Can set up a multiple schedules to auto turn on/off do not disturb and then allow exceptions from favorite (starred) contacts. You can also allow an exception from someone who calls you 3 times back to back in case they’re calling you from someone else’s phone. And can also allow some apps as exceptions in case you use a 3rd party alarm app or something else that you want to be able to make noise.
