Is there really an app that pays you?

I've been hearing about apps that promise to pay users for their time or participation, but I can't help but wonder - is there really an app that pays you? It seems too good to be true, almost like a scam waiting to happen. Could you enlighten me on this matter? Are there legitimate apps out there that genuinely reward users for their engagement, or is it all just a pipe dream? I'd appreciate any insight you can provide.
