iOS 27 landed at WWDC on June 8, 2026, and it is already on developer betas, with a public beta due in July and the full release expected around September. The headline features are Apple Intelligence and a faster Siri — but if you sideload apps, your question is more practical: can you still install apps from outside the App Store on iOS 27, and if you update, do the apps you already have survive? The short answer is that sideloading still works, and whether an update is safe depends entirely on how your apps are signed. Here is the breakdown.
- Announced: WWDC keynote, June 8, 2026
- Developer beta: out now
- Public beta: July 2026
- Public release: expected around September 2026
- Supported devices: iPhone 11 and newer
Does sideloading still work on iOS 27?
Yes. Apple did not close the door in iOS 27. Developer Mode — the toggle that lets apps Apple did not sign run on your phone — is still there under Settings → Privacy & Security → Developer Mode, and the certificate-based methods that power sideloading still function. The free tools have already caught up: SideStore paired with LiveContainer is running on the iOS 27 beta, so the core approaches all carry over.
It helps to remember what sideloading is and is not. It does not modify iOS or remove Apple’s protections — it just installs an app Apple did not approve. That is why a new OS rarely kills sideloading outright. What a new OS does do is shake the ground under the methods that depend on constant upkeep.
The real risk on a new iOS: the update gamble
Here is the part nobody mentions before you tap Update. Free sideloading setups are fragile by design, and every new iOS — especially the early betas and the first point releases — tends to break them until the tools are patched. On iOS 26 it was the 26.4 and 26.5 updates that sent a wave of SideStore and LiveContainer users back to rebuilding their setup from scratch. A brand-new major version like iOS 27 is exactly when that risk peaks.
So «should I update to iOS 27?» has different answers depending on how your apps are signed:
- On a free setup (SideStore, LiveContainer, AltStore), treat the iOS 27 beta as a hobby, not a daily driver. Expect breakage, and be ready to re-pair, re-sign, and reinstall when an update lands.
- On managed signing, an OS update is a non-event. Apps are re-signed as needed, so moving to iOS 27 does not mean rebuilding anything.
What an iOS 27 update does to each method
| Method | Works on iOS 27? | What an iOS 27 update does to your apps |
|---|---|---|
| SideStore + LiveContainer (free) | Yes, once patched | Often breaks on each update — expect to re-pair and re-sign |
| AltStore PAL (EU only) | Yes | Apple-sanctioned and stable; EU accounts only, smaller catalog |
| Certificate stores (grey-market) | Unreliable | Shared certificates get revoked in waves, update or not |
| builds.io (managed) | Yes | Apps re-signed for you — nothing to rebuild |
The grey-market certificate stores deserve a flag of their own. They skip the seven-day limit by signing thousands of users with one shared enterprise certificate, and Apple disables those in revoke waves — an iOS 27 update is the least of the reasons your apps can vanish overnight. We covered exactly why that happens, and how to avoid it, in why sideloaded apps get revoked.
How to sideload on iOS 27 without a computer
The shortest path on iOS 27 needs no computer, no VPN, and no seven-day timer:
- Open builds.io in Safari on your iPhone.
- Pick an app from the catalog and tap install.
- Trust the profile once in Settings if you are prompted.
- Open the app from your home screen — there is no refresh schedule to keep.
That is the whole process, and it does not change when iOS does. If you would rather go the free route, our AltStore vs SideStore vs LiveContainer comparison and the iOS 26 sideloading guide walk through every method step by step — all of them carry over to iOS 27.
Popular apps to install once you are set up
Whatever method you pick, these are the kinds of apps people sideload the moment they are set up on iOS 27:
Runs GameCube and Wii games on iPhone — console emulation the App Store will never approve. It is a textbook reason to sideload, and it does not care which iOS version you are on as long as your signing holds up.
A patched Spotify that unlocks the paid features — no ads, unlimited skips, offline downloads — on a free account. It looks and updates like the normal app, just without the paywall. For more, see the best apps to sideload on iPhone.
Will your apps survive the move to iOS 27?
So, should you update to iOS 27? If your apps are signed for you, go ahead — managed signing carries them through the update, and on the Premium plan a revoked certificate is replaced automatically, with any Apple cooldown credited back as free time. If you are on a free setup, hold off until the tools catch up, or move to a method that does not break every time Apple ships an update. Browse the catalog at builds.io and install your apps in a couple of taps — on iOS 27, and whatever comes next.
