How do I add a device onto my find my iPhone account?

Turn on iCloud on that device, also turn on "find my iphone" in settings

You can set up Find My (insert device name here) on as many devices as you wish; just repeat the steps above on each iOS device. The next time your iPhone falls behind the couch cushion, or some stranger makes off with your iPad after leaving it on your table in a coffee shop, you have the ability to not only find the device, but also prevent anyone from accessing your information.
