Bumble is really similar and disgusting. By default, notifications are enabled for both messages (which are a pretty good thing to have notifications turned on for) and once or twice a day Peak Cringe marketing push notifications. They have the ability to turn off specific kinds of notifications, but one of the categories is "The Good Stuff: Turning these off means you'll miss out on our most exciting pushes of all!" and I'm not unconvinced that this is actually their daily CTAs to get you back into the app, because none of the other categories cover those.
Instagram for me. I don't use it much but have a few friends who message through it, or at least send some memes. If I enable notifications for that, I get daily notifications that someone I might know has joined Instagram, someone I know posted to their story... It's about 1:4 real notifications vs "Please spend more time on our app"
As soon as I get to a point where I would normally get zero notifications from FB/IG, they invent a new way to give me a notification. Always.
Usually it's something like "Group x has a new post, click to read it now!" where X is a group I haven't visited in years and would never give me a notification before. So I click "Only get notifications for friends posts in this group" and then it happens again with one-three other random groups the next week.
It's all about trying to get the user to spend the most amount of time in the app.
Another disgusting thing they do is push promo notifications with the title “1 new match?” where the question mark is the only difference from an actual app notification.
Tinder gets around this by sending fake "You have a new like" or "You have a new match" message nearly daily. You open the app and have neither. I turned off all notifications except new messages to get rid of this.
Well, you can turn everything off except messages so I don't see it as that big of a deal. I don't install many apps on my phone so going into the app settings and turning off notifications isn't a big deal.
