Use It if You Don’t Want to Install the Same App on All Your Devices
Not everyone can afford a Mac with 1 TB of storage, and some don’t want to download the same app over and over again.
Using iPhone Mirroring lets you access any app you have already installed without having to add it to your Mac. Of course, if you plan to use that app on your Mac more often than on your iPhone, you might be better off installing it on your desktop instead.
