We have at least three tags for Apple mobile devices: ios, iphone-app and ipad-app.
I guess iphone-app and ipad-app should be iphone and ipad instead — what question about those devices wouldn't be about an app for these devices?
Are separate iphone and ipad tags needed at all, or should ios be systematically used ([perhaps with smartphone or tablet to distinguish when needed)? After all we have a single tag for android.
According to Wikipedia, there are only half as many iPad apps as iPhone apps, so there is a significant difference in availability. Does this justify treating iphone and ipad as separate platforms? In that case, is ios warranted?
