On Android I used to have an app that would just kill most notifications. If you got a notification, the app would put its own notification on the bar, and not turn the light on or ping you.

So even if I got 3 text messages, 2 missed calls, and other random notifications, the bar would show only one notification, and I would not get a sound/light. You'd have to click on it to see the actual notifications you missed.

You could, of course, have whitelists to let certain notifications through.

Best. App. Ever. It's great to be able to work or do whatever for hours, knowing that your phone can't interrupt you (unless someone calls, which they rarely do).

Sadly stopped working after some Android update. I'm sure there are similar apps, though.

At least apps have to ask permissions for notifications now, and you can deny it outright from the start. In years prior I remember trying to hack things with Tasker and extensions, but it's just not needed to nearly the same degree now.

And if the app is good, it will categorize it's notification types in a user-centric way and allow you to enable only specific categories.
