Legizmo is a series of apps, originally designed for iPhones running iOS 12.0 and newer. Its primary function is to enable the use of Apple Watches running versions of watchOS that are too new for the version of iOS running on the user's iPhone. These older versions of iOS are typically used by those running or awaiting a jailbreak, or when iOS updates are no longer produced for the user's iPhone. It released in beta on 21 September 2020, before being made available on Chariz on 15 February 2022.
Since the release of watchOS 8, a new major release of Legizmo has followed each new major watchOS release. Each version of Legizmo is named after the build train of the major watchOS version it introduced support for, but continues to support all versions of watchOS Legizmo has ever supported previously.
Pairing Support
Pairing Support is the core component of Legizmo. It facilitates the pairing, updating, and general continued use of an Apple Watch whose version of watchOS is too new for the iPhone's version of iOS.
Compatibility Fixes
Compatibility Fixes are additional modules bundled with Legizmo that are designed to bridge the gap in individual feature compatibility when using unsupported firmware combinations. Pairing Support must be installed to utilise these.
Many features that rely on communication between the Watch and its paired iPhone are facilitated by binary-encoded messages sent over Bluetooth. Occasionally, watchOS updates change the structure of these messages, and these changes are also made in a corresponding iOS update. Compatibility Fixes can be installed by Legizmo into various system daemons that effectively translate between the new and old structures so that both devices are able to process the messages. Occasionally, additional functionality has to be adapted in order for completely new features to be supported.
Releases
Lighthouse
Legizmo Lighthouse was initially made available shortly after watchOS 10 was released, on 22 September 2023. It launched on Chariz on 3 November 2023.
Kincaid
Legizmo Kincaid was initially made available shortly after watchOS 9 was released, on 23 September 2022. It launched on Chariz on 25 November 2022. As well as the regular version for jailbroken users, a special edition designed for use with TrollStore was also made available.
Jupiter
Legizmo Jupiter was initially made available hours after watchOS 8 was unveiled at the 2021 WWDC Keynote, on 7 June 2021. It launched on Chariz on 15 February 2022. Jupiter also was the first version of Legizmo that did not support iOS 12.
Grace
Legizmo Grace was the initial version of Legizmo, made available on 21 September 2020. This set of releases originally used 1.x version numbers and was simply known as Legizmo, until its Chariz launch on 15 February 2022. It was then re-versioned to 2.3.1 and assigned the name Grace. Despite this being the build train name for watchOS 6, it also included support for watchOS 7.
