Has anyone got the app Pen Pals? Whats's it like? Is it any good?

[KidC81]

I'm looking to download the pen pals app as I'm just lookin to make new friends from across the world
However (yes call me cheap lol) before I pay for the app I thought I'd get some feed back about it
Alternatively I'd welcome suggestions for other apps that will basically do the above
Thanks for taking the time to read this & even more thanks if you post a reply
