Are there any differences between the iPhone version of FMH and the iPad version?

Or are there planned to be in the future? Given that the iPad is more powerful. Not being funny, just curious.

The iPad isn't actually any more powerful than the iPhone (although often the phone processors are slightly 'under-clocked'), thats a misnomer that people frequently have about the devices - the iPad2 was more powerful than the iPhone4, but now the 4s is out thats no longer the case.

I'd expect the speed of the two devices to continue 'leap-frogging' in the future as technology evolves - simply put its easier initially to integrate new processors into the iPad because it has more space in it than a mobile phone, but the 'second generation' tends to overcome these restrictions and allow phones to follow suit fairly quickly.

In general usage in fact you'll find the phones out-perform the iPad equivalents because they have a smaller screen size to render which means they can do so faster than the iPad can.

As such the differences with FMHi on the iPad are down to the larger screen space, there is a specific 'HD' skin for it which has a reworked appearance and is designed to make things as easy as possible to navigate on the iPad - there is also additional information displayed on this skin in comparison to the iPhone.

The save games are totally interchangeable between all iOS devices - so you can take a save game from your phone, play it on your iPad and then return it to your phone later if you so desire ..
