What's your experience on Bumble and other apps? (Tinder, Happn, Fruitz, Hinge, Once...)
How long have you been using these apps? (weeks, months, years...)
Which kind of people did you met on? (wird, respectful, nice, ghosting...)
Did you notice differences between the apps? (number of likes, fake profils, not prenium functionalities, localization efficiency...)
Finally, are you satisfied about these apps?
To summurize my experience, as a "normal" french guy in a big city, I think these apps are a little bit frustrating...
