The UDID (Unique Device Identifier) is a sequence of numbers that is associated with each iOS device. Actigage will require UDIDs when we register devices in the Apple Developer Program. This allows you to test the mobile app before it is published in the Apple App Store.

Below are the steps to find your UDID:

Step 1: Open iTunes on a computer and connect your iOS device.

Step 2: Click on the phone icon.

Step 3: At the Summary tab, your device’s information will be displayed.  Click on Serial Number to display your UDID.

Step 4: This is your UDID.  Copy the UDID and send it to the Actigage team.
