Just read a review of a new email app called Airmail. It looked interesting, so I did an app store search on my iPro. Zilch! Then I realized that under iOS 9.2 I have only two choices: iPad only and iPhone only. What has happened to what they called "universal" apps (or somesuch---a sorta' misleading name to be sure.) Will that "iPhone only" app work on my iPad ir not? In the App Store description, deeply imbedded, it says it is "compatible with" the iPad. But all the detailed description deals only with the iPhone. Does anyone have an insight on this general issue? Thanks.
