How to Install an IPA on iPhone Without the App Store
Four ways to get a build onto a device without App Store review — and the fastest one takes about 30 seconds.
The 4 methods, compared
| Method | Setup | Limits | Best for |
|---|---|---|---|
| OTA install link (itms-services) | Sign with ad-hoc or enterprise cert, upload IPA, share link | Device must be in the provisioning profile | Fastest internal testing |
| TestFlight | Apple Developer account + App Store Connect | 90-day build expiry, external testers need Beta App Review | Formal beta programs |
| Sideloading tools (AltStore, Sideloadly) | Free Apple ID or developer account | 7-day re-signing with free ID, one computer required | Personal use, small teams |
| Enterprise distribution | Apple Enterprise Program ($299/yr, D-U-N-S required) | Apple restricts to internal employees | Companies distributing internally |
The fastest method: an OTA install link
Over-the-air (OTA) installation uses the itms-services protocol: iOS downloads a small manifest pointing at your signed IPA and installs it directly. Full protocol breakdown here.
- Sign the build. In Xcode, export with Development or Ad Hoc distribution and include the tester's device in the provisioning profile.
- Add the tester's UDID. Use our free UDID collector — testers open a link, install a profile, and their UDID lands in your list. No cables.
- Upload the IPA to Build Installer — you get an install link and QR code instantly.
- Share. Testers open the link (or scan the QR) in Safari on their iPhone, tap Install, and the app appears on their home screen.

Upload your IPACommon questions
Do I need a jailbroken iPhone?
No. OTA install links and TestFlight work on stock, up-to-date iPhones.
Why does my install fail with "Unable to Download App"?
Almost always one of: the device's UDID isn't in the provisioning profile, the certificate expired, or the manifest isn't served over HTTPS. The manifest must be on an HTTPS server — ours is.
Can I install without any Apple Developer account?
With free Apple ID signing via AltStore/Sideloadly, yes — but builds expire after 7 days and re-signing needs the computer. For anything professional, ad-hoc or TestFlight distribution is the reliable path.
