Meeting people irl sons meeting them through an app any time in my book.
But there is nothing wrong with said app, just with the person’s way of using it. Like you said: expectations. As long as you’re realistic about what it is and just use it to meet people then it’s pretty great really. It just shouldn’t be anything more though. As soon as you project a desired outcome on these meetings you’re gonna be dependent on it. Which I think is also the case in the offline version.
So while I agree the real life version is usually more exciting, I don’t think that detracts from the app itself. It’s not a competition. Just two different ways to meet people.
