Don't worry, not caring about social norms is attractive
Just make a move in real life
The problem with dating app is exactly what you mentioned: if you both know you're there to date or fool around there's no uncertainty, no tension.
You're missing out on the feeling on trying to pickup a beautiful girl and succeeding.
Besides, girls, unlike boys, compete mainly on looks. It's natural dating app will break the balance in favor women, and that's exactly what happens. Men have a tenth of the matches and are selected by women according to beauty standards instead of being evaluated by their behaviour, providing a terrible filter for dating.
If in person you had a chance with some jokes and some confidence, you'll never pass the selection with that nose.
