FlexClock

Replaces the iOS lock screen clock with images, and lets you install your own digit packs.

Built against the CoverSheetKit lock screen, for iOS 18.

Features

• Animated (GIF or APNG) or static digits
• Adjustable animation speed
• Installable digit packs, imported and removed from Settings
• Optional switch to still frames while Low Power Mode is on
• Adjustable digit size, spacing and vertical offset
• 12-hour / 24-hour / system time format
• Optional date hiding
• Colour tinting that keeps the artwork's shading, the way iOS tints app icons
• Settings apply live, no respring needed
• Falls back to the stock clock if the selected pack is missing or broken

Requirements

• iOS 18, rootless jailbreak (developed on 18.5, Dopamine 3.0.4)
• preferenceloader
• ElleKit / Substrate

Installation

Add the repository in Sileo:

https://tr3tol.github.io/repo/

Or install a release .deb by hand:

dpkg -i com.tr3tol.flexclock_1.0.1_iphoneos-arm64.deb
killall -9 SpringBoard

Settings live under Settings → FlexClock.

Digit packs

Four packs ship with the tweak — Anime, Pixel, CRT and Sakura — and Anime is the default.

Packs are plain folders. The bundled ones live here:

/var/jb/Library/Application Support/FlexClock/Packs/

Imported ones live outside it, so they survive updates and can be managed from Settings:

/var/mobile/Library/FlexClock/Packs/

A user pack shadows a bundled pack of the same name, so the included artwork can be replaced without touching the installed package.

A pack is a folder whose name ends in .flexpack:

MyPack.flexpack/
├── Info.plist
├── animated/          # optional
│   ├── 0.gif … 9.gif
│   └── colon.gif
└── static/            # optional
    ├── 0.png … 9.png
    └── colon.png

• At least one of animated/ or static/ must exist. If the folder for the selected animation style is missing, the other one is used.
• .gif and .png are both accepted in either folder, and animated GIF and APNG both play at their own frame timing. APNG is worth the larger files when the artwork has soft edges: GIF carries a single bit of alpha, which turns a glow into a ragged halo. A glyph is looked up as .gif first, so a pack ships one format or the other, not both.
• Digits are laid out by their aspect ratio, so frames do not have to be square or share a common width.
• Info.plist is optional; without it the folder name is used as the title.

<dict>
    <key>Name</key>    <string>My Pack</string>
    <key>Version</key> <string>1.0</string>
</dict>

Settings → FlexClock → Manage packs lists what is installed, imports a pack folder and removes the imported ones. A folder is only accepted if it actually contains digits; if the pack sits one level below what you picked, it is found there. Copying a folder into the directory above works just as well.

Packs can also be shipped as .deb packages that install into the bundled directory.

Building

Requires Theos with a rootless setup:

make package THEOS_PACKAGE_SCHEME=rootless
