A UDID is an acronym used for Unique Device ID. It is a feature of Apple
iPhones and their other devices. Each individual Apple device has their own ID that is being fetched
by Apple servers.
Why do I need to share it?
When testing a new mobile application on an Apple device we need a UDID
from the iPhone, iPad or iPod. So, in order for you to be able to test your new application on your
own phone or tablet, you will need to provide us with the UDIDs from your personal devices.
With TestApp.io, you can get feedback by sharing your app with an unlimited
number of public testers with a public link and a fully customizable app install page on
TestApp.io
With the detailed analytics about your testers geolocations, device type, system
version,... you will debug issues much faster
