Range can send remote alerts to any iOS device after pairing. Just connect your Range to the device you want to get alerts on and Range will remember it and send alerts (as long as both devices are connected to the internet).

Note that pairing may not work the first time you launch the Range app. You'll need to quit the app (double-tap the home button and swipe up on the Range app's screen to quit it), and then relaunch it. When you plug Range in now, it will pair.
