Q: I’m getting a new iPhone. Will I be able to use the iPad apps I’ve purchased on my iPhone? (Or, I’m getting a new iPad. Will I be able to use the iPhone apps I’ve purchased on my iPad? )
A: Yes, some of your apps will probably work – it depends on the specific ones you’ve purchased. Here’s how it works -
Some apps are designed specifically to work on both the iPhone and the iPad. These are called “Universal Apps”. Any universal apps that you have purchased should work on any of your iDevices, as long as the operating system is current enough. You will not have to pay for these again, either! Once you have bought them, you will have a license to install them on any of your compatible iDevices. (iPads, iPod Touches, iPhones) To install an app on your new phone, you can simply pull up the app in the Store, and tap “install”.
Other apps are designed specifically for the iPhone. Almost all of these apps will also work on the iPad. They will not be optimized for the iPad’s larger screen, so you will be able to view them on an iPhone shaped section in the center of your screen. You will also have the option to zoom to a full screen mode by tapping the x2 button. This will almost certainly make the graphic images and text fuzzy. I prefer to just use regular sized, but you have zoom if you need it. The only apps that won’t work on the iPad (at least, the original iPad, anyway) will be apps that make use of a camera function. Since the original iPad doesn’t have a camera, some of those apps either won’t install, or will have limited functionality. But by and large, most iPhone apps work on the iPad.
Finally, there are some apps that are designed specifically for the iPad. These will not work on the iPhone at all. Now that the iPad 2 is out, there will likely be a number of apps coming out that are designed specifically for the new features of the iPad 2. It remains to be seen whether most of them retain support for the iPad and just offer extra capabilities if you do own an iPad, or if they will be exclusively for iPad devices. My guess is that there will be a mixture, but that’s just a guess. We shall see!
