All iOS apps featured here have been updated for iPhone 6 and 6 Plus – with resizable launch screens, auto layout and landscape orientation support. All of these make the apps essentially independent of the device screen size, and hence all of them now run without scaling on the iPad as well!
Of course whether that is required is another matter, an app such as Divert Calls would meaningless to have on on iPad, so would Ticket Wallet, more or less, since the tickets must be copied from SMS messages – but still, if installed, they do run happily on the large screens.
The apps that already supported iPad (Train Alarm, IV Thrombolysis) will continue to do so but designing the layouts for iPhone 6 & 6 Plus has lead to several further tweaks which improve the overall interface even on smaller iPhones (I suppose that’s what we’ll be calling iPhone 4 & 5 hence forth!).
However, the app that benefitted the most is: Train Status – it now a Universal app, that can be installed, and runs without scaling on all screens, from iPhone 4 to iPad – and thus being available now for two whole new families of devices.
