Android app

[Rockingit]

Unless I'm being very dumb........

I can't find the app in the market place, so instead I browse to the google play link...find app and it then won't install...so I investigate further and my HTC phones (both older and spanky new), along with seemingly every other android phone on the market, are 'invalid devices'.

So in short, the forum's got its own app (great) for android, that actually no-one can use???
