When event organisers find the iPad too cumbersome in terms of portability, they always have the preference to use an iPhone event app. While the event app is basically accessible through any iOS device, the iPhone is at the forefront of Apple products and thus it is more likely that organisers already have an iPhone rather than iPads.
iPhones also have data connection, as compared to some iPads that may only be used with Wi-Fi.
Event App for Iphone
Like any iOS device, anyone can look for a reliable iPhone event app through a simple search in the App Store. An event organiser simply has to ascertain if the modules or functions that he or she would want to utilise are integrated in the mobile app.
