Not sure how you got that I'm thinking its a game but let's rephrase anyway: Tried searching for toucharcade "on the" app (Tapatalk) and is not finding it. Not supported perhaps? add: ok, I can see how you might have misread after reading my earlier post.
I take it this is what's being discussed? https://itunes.apple.com/us/app/tapatalk-forum-app/id307880732?mt=8 App info is currently processing and/or the app is not yet fully available for sale on the US App Store.
Its a great app in theory, I bought it but honestly never really did find any forum that I use listed on it. Still cant go wrong with free.
I know, right? I use it exclusively for the Sims 3 forum. It's weird, I play so many games you'd think I could find another forum on there. Oh, well, it's a nice app.
