It's because the concept dating apps is fatally flawed; it's just taken the public a while to learn this lesson.

They're fatally flawed because every dating app has a imbalance between men and women; leading to frustration on both sides. Men are prone to using them to attempt quick hookups dirty or abusive messages and women become excruciatingly picky while using them due to the endless choice they have.

Every single dating app will have exactly the same outcome.

The public has now tried dating apps for a prolonged period of time, understood that they're awful, learned the lesson, and are now returning to the real world to find dates.
