Undercover ^^ alternatives

I just downloaded it to my iPhone. First joke made me laugh. I'm not clear how often the jokes are changed - once I hit the "laugh" icon again, it gives me the same joke. Also, I'm curious if I'm receiving the same joke as everyone else - I like the idea of everyone laughing (or not) at the same joke in real time. If that's the case, it would be fun to eventually see a world map of where people are laughing. Finally, I like the streak feature - promoting regular laughter and use of the app. Congrats on your launch and thanks for making me laugh today.😻
