Why we
made it

User testing is a large part of building an iOS App. When the time comes we send clients periodic builds of their app via iTunes Connect or Crashlytics by Fabric.io. The trouble has always been obtaining the "Unique Device Identifier" / UDID of a user's iPhone or iPad, which is required to authorize the app for that device. There wasn't a simple, reliable, and secure way of telling our clients to send us their device UDID. So we wrote a script to do it. And it's free for the world to use. Hey, you're welcome!
