How to know on app store if an app is universal or has 2 binaries

Question

Can I tell if an app that is featured on both iPad store and iPhone store are 2 different binaries or just one universal app ?

Can I assume that if it has the "+" it's universal and if it's not it's 2 different binaries ?

Thanks

Answer 1

Yes the '+' sign indicate that a app is universal if a + sign is not there and you see the app on iphone it will be iPhone only or if you see the app on iPad store it will be iPad only.
