Agree 100%! It's really annoying how games (yeah, I confess, I installed a "free-to-play" game recently, I should have known better) and over-gamified apps (looking at you Duolingo) want to "engage" you by flooding you with notifications. "You're back at full hearts, use Duolingo now!" "Only 00:59 left to continue your streak!" (with a live countdown in the notification no less) and so on...
