Legizmo 'Jupiter' (watchOS 6 - 8)


For iOS 12, use Legizmo ‘Grace’ instead.
For watchOS 9 support, or if running iOS 15, use Legizmo ‘Kincaid’ instead.

Got a shiny new Apple Watch, but when you try to pair with your jailbroken iPhone you find that iOS says ‘no’? Torn between whether to stay jailbroken and not use the Watch, or whether to use the Watch but sacrifice your jailbreak and update iOS?

What if you could have it both ways? With Legizmo, you can.

Whether you’re trying to pair a brand-new Apple Watch that’s running a version of watchOS that’s too new for your jailbroken version of iOS, or you are already paired but want to update watchOS to take advantage of the latest features whilst still keeping your iPhone jailbroken, Legizmo is designed to help make that happen.

Legizmo ‘Jupiter’ is designed to enable you to pair Apple Watches that are running watchOS 1.0 right up to the final version of watchOS 8 on iOS 13 or newer. The Legizmo app walks you through the setup process, and offers three key features:

Pairing Support

There are two methods of Pairing Support to choose from, and the Legizmo app will help guide you through the selection and installation process. This is the magic that lets you pair and update to newer versions.

Compatibility Fixes

What about features added to watchOS that your version of iOS is too old to have? Blood Oxygen on iOS 13? Legizmo offers a set of Compatibility Fixes tailored to your combination of iOS and watchOS devices, to bring new functionality back to older versions of iOS, or to fix potential inconsistencies with existing features.

Verify Support

Looking to buy a Watch, but not sure if it’s compatible? If it’s out of the box, Legizmo lets you scan the pairing code on any Apple Watch to see what version of watchOS it’s running, and whether your version of Legizmo is compatible with it (or, if it will just work with your current version of iOS)

watchOS Software Updates

What about software updates? With Legizmo, you can unlock software updates again for your Apple Watch. And, if the version of Legizmo you’re using isn’t compatible with the available update, that update is prevented. An update to Legizmo would bring support for that new version, and will then allow you to update your Watch once more.

Feature Compatibility

Especially when using major versions of watchOS with older major versions of iOS (like watchOS 8 with iOS 14), there will inevitably be some incompatibilites with certain features. Compatibility Fixes help with this, but, full compatibility with all features can’t be guaranteed
