Your UDID appears on screen and is emailed to you. Share it with your developer.
A UDID (Unique Device Identifier) is a 40-character alphanumeric string that Apple assigns to every iPhone and iPad. Developers need it to register your device in their provisioning profile so you can install ad-hoc or beta builds that aren't on the App Store.
Yes, completely free. Enter your email, download the profile, and your UDID is displayed and emailed to you. No account or payment required.
Yes. A UDID alone cannot be used to access your device, install apps without your consent, or track your location. It's only used by developers to include your device in their Apple Developer provisioning profile so you can install beta builds.
This tool works entirely on your iPhone — no computer needed. Enter your email, tap the link we send you, download the profile, install it in Settings → Profile Downloaded, and your UDID is captured automatically and emailed to you.
The profile is an Apple Configuration Profile that asks your device to send its UDID, model, and iOS version back to AirBuild. It does not install any app, change your settings, or persist on your device — you can remove it immediately after from Settings → General → Profiles & Device Management.
We store your UDID temporarily so we can email it to you and display it on the result page. We do not share it with third parties. You can request deletion at any time by contacting us.
AirBuild collects UDIDs automatically when testers open an install link — no profiles, no copy-paste.
