Why it is worth attention

It reimplements a popular tweak set as modern in-process substrate hooks for the latest jailbreakable iOS version, providing a unified, MIT-licensed package with immediate animation toggles.

Who it is for

Jailbreak users on iOS 17.0–17.3.1 (Relaxin)
Tweak enthusiasts wanting customizable SpringBoard
Developers looking for a clean substrate hook implementation reference

Use cases

Adjust dock icon count (4–7) and preserve them across resprings
Customize home screen grid columns/rows and icon spacing
Scale home screen and dock icons independently
Disable wake/sleep animations and double-tap-to-lock on lock or home screen

Strengths

Bundles many popular tweaks into one package with a single preference pane
Animation switches apply immediately without respring
Respring button included for other settings
Open-source (MIT) and built on the roothide theos fork for modern jailbreaks

Considerations

Only compatible with Relaxin jailbreak on iOS 17.0–17.3.1
Most changes require a respring
No support for older iOS versions or other jailbreaks

README quick start

SBTweaker

A collection of SpringBoard tweaks in a single package, with a preference bundle. These are reimplementations of my DarkSword Tweaks for the Relaxin jailbreak (iOS 17.0 – 17.3.1), converted from out-of-process RemoteCall code to classic in-process substrate hooks.

Features

Dock: configurable icon count (4–7), plus optional restore of extra dock icons across resprings and icon-state validation
Home Screen grid: configurable columns (3–7) and rows (4–8)
Spacing: extra layout insets for the Home Screen (L/R/T/B) and dock
Icon scale: separate scaling for Home Screen and dock icons
Hide App Library: removes the App Library page
Double Tap to Lock: separate switches for Home Screen and Lock Screen (ignores icons, folders, dock and the passcode pad)
Animations:
- Drag Coefficient slider (UIAnimationDragCoefficient, 0.01–2.00, default 0.25; 1.0 = stock, leaves the system value untouched)
- Disable Wake Animation (screen on)
- Disable Screen Off Fade (screen off)
- Disable Unlock Icon Fly-In

All settings live in Settings → SBTweaker. Changes take effect after a respring (a respring button is included); the animation switches apply immediately.

Building

Requires the roothide theos fork installed at ~/theos-roothide (adjust the THEOS export in the Makefile otherwise) and an iOS 16.5 SDK. The Makefile already sets THEOS_PACKAGE_SCHEME=roothide.

make package FINALPACKAGE=1

The resulting .deb lands in packages/.
