Windows/Mac/Android: If you want to show off your iPhone or iPad screen, typically you need an Apple TV. Reflector puts your iOS screen on a Mac, PC or Android device by acting as an AirPlay receiver.
AirPlay is already built into iOS, but you'll need to buy a version for the device you want to mirror to. The Windows and Mac versions cost $US12.99 each (no bundle), and the Android version is $US6.99.
After you install it, mirror your iPhone or iPad with the AirPlay icon in the control centre. Reflector lets you record the broadcast from your iOS device, so it's great for training.
