Well I bought it as well it is great for the iPad 3 and have no problem connecting and turning the scope around with WiFi .
On the iPhone 4S the new controls to turn the scope around are too intrusive for the small screen the iPad is fine all round it is a great upgrade and has all the bells and whistle's of more expensive programs on the market for PC's.
Hope the Android version is the same.version 1.85 is great and has the extra bonus of Bluetooth compared to iPads and iPhones not having that function for controlling the scopes.
A++
If I was going to buy another tablet it would not be a iPad it would be the Samsung Galaxy Note 10.1 2014 edition they are fantastic with SkySafari.
