I'm old, but Tinder works really well for me. I only go on until I can start messaging with a couple girls. Usually, one will seem radder and I'll push to get that to texting. After that I turn my card off so my profile isn't visible. Then I'll plan out a nice dinner and drinks. Most the time that works and I'll suggest going back to either my house or her house. If there's no connection in person, it's better to just cut your losses after the first date.
I use it as a dating app, not a hook up app. However, it usually leads to hooking up.
