Aha has been designed to work with all currently available iOS devices that are compatible with iOS 6 and 7. This includes iPhone, iPad, iPad Mini, and iPod Touch.
While Aha will work on devices that do not have their own cellular data plan, please remember that an active network connection is required to access our service. This means that an iPod Touch or iPad model that does not have a cellular plan can connect via a local wifi network or a portable hotspot from another mobile device.
The app has not been optimized for the tablet interface, but performs well when zoomed in. It has been designed for both iPhone screen dimensions, so whether you have a 3.5" screen on an older iPhone, or a 4" screen on a newer model, the app should display correctly.
