Hey, Sky? You do know that the same Google Play Store listing can be used for both smartphone and tablet versions of an app, right? No? You're still going with separate smartphone and tablet apps, like it's 2010? Okay then. The Sky Go tablet app has the same basic features of the smartphone app, but it's restricted to 7" or larger tablets running Android 4.0 or later.
Kidding aside, the feature set of the Sky Go app is pretty admirable, with live TV and streaming TV on demand.
