Ketamine

On-Device MobileGestalt Editor for iOS

Ketamine is an on-device MobileGestalt editor that lets you modify supported system values directly from your iPhone — no PC required.

⚠️ Experimental: Many features in Ketamine are still untested across all devices and iOS versions. Things may not work as expected. Please report bugs, issues, and compatibility results in our Discord.

Features

Requirements

iOS 26.0 or newer. Tweaks and Siri AI Setup additionally require iOS 27 — see the table below.

Compatibility

iOS Version MobileGestalt Editing Customization
iOS 18.x and earlier ❌ Unsupported ❌ Unsupported
iOS 26.0 – 26.6 ❌ Unsupported ✅ Supported
iOS 27.0 Beta 1 – Beta 4 ✅ Supported ✅ Supported
Later versions ❌ Patched ❌ Unsupported

Note: On iOS 26, the exploit does not provide the access required for MobileGestalt editing, so tweaks are unavailable. PosterBoard may still work, but compatibility has not been fully verified.

Siri AI Setup is beta. It can cause instability, boot loops, or require a device restore, and the Siri AI mode in particular is the least reliable feature in Ketamine — it may have no effect at all. Every key it touches is saved first, so its changes can be reverted. Back up before using it.

Ketamine
What is this?Ketamine is an on-device MobileGestalt editor for iOS: it changes supported system values straight from your iPhone, with no PC involved.
What can it actually change on my phone?Supported MobileGestalt keys, grouped into Device, Display, System, Liquid Glass, iPad and Intelligence categories — plus device spoofing.
Which iOS version do I need?iOS 26.0 or newer, but only iOS 27.0 Beta 1-4 unlocks everything: on 26.0-26.6 tweaks are unavailable (the exploit can't reach MobileGestalt), and versions after Beta 4 are already patched.
How experimental is this in practice?Very — many features are untested across devices and iOS versions, and Siri AI Setup is beta: it can cause instability, boot loops, or require a device restore. The author says to back up first.
Does everything stay on my phone?Yes — editing runs entirely on the iPhone with no PC in the loop; the README describes no server component.
What can I customize besides system values?PosterBoard support with a built-in Nugget-Wallpapers gallery, a choice of eight alternate app icons, and an accent colour picker.
Can I undo the changes it makes?Yes. Portable backups let you export a recovery point to Files or AirDrop and import it back, and Siri AI Setup saves every key it touches before changing it.
Where does the project come from?It builds on published proof-of-concept research: MobileHouseArrest-PoC by 0xjohnnydev, the badquery implementation by forcequitOS, Pocket Poster by leminlimez, and NeoSpring by rooootdev.
What are similar projects?GestaltEdit, AirCard-iOS, Erosion, 3105, placard, AirBeep, SkeletonView, misaka26
