I can second buzzkill. I was getting frustrated with group chats during work hours buzzing my phone (and my watch) with every single message as they came in. It was incredibly distracting during meetings and such (and putting my phone on silent wouldnt stop the watch notifications). I tried buzzkill to add a “cooldown” to the push notifications for anything that happened twice in a few minutes. You can absolutely set rules on notifications based on things like time of day, or on specific apps.
