Having read this thread I couldn't resist quoting the following from the Aberdeen MRC website:
"So why iOS and not Android? If you know me, you may be forgiven for thinking its because I hate the fact Android was stolen from Apple while there was a Google Exec on the Apple board. However, much as the previous statement is true, it is not the case. The simple reason is that Android, being an 'open' platform, is very fragmented. What this means is that each licensee of Android (phone manufacturer) can make their own little tweaks to the software. Also hardware is never the same even within the same manufacturer. This makes App development difficult, and for a niche so small as ours, it become hardly worth writing an App for Android. That is not to say there is not an Apps - there may well be, however it adds complications into the mix for end users which is why I suggest to stay clear of Android to control your layout. The last thing we want in our hobby is more frustration! With iOS your App is virtually guaranteed to work out the box, first time, every time."
