Good to know

  • The UDID is the unique identifier of an Apple device. You need it to register test devices and to sign test builds for them.
  • This tool uses Apple's own Profile Service mechanism. The profile expires immediately after the request and cannot read your contacts, photos or any other personal data.
  • Results are cached on the server for 30 minutes only. After that, scan the QR code again.
  • With the UDID you can use Appuploader on Windows/Mac to register devices and create certificates and provisioning profiles.
