Make your phone's theme your own. ChaoMe Theme Editor opens a theme you already have, or a .mtz file you downloaded, lets you change what you want, and builds a new .mtz theme for MIUI and HyperOS phones. No PC needed.


WHAT YOU CAN EDIT

• Wallpaper, lock screen and always-on display: your own pictures, the lock screen's options, or a new lock screen of your own with clock, depth layers and a dark-mode version
• App icons: from installed icon packs, a zip or folder of images, or single pictures; icon masks, batch effects, two-layer Monet-style icons and dynamic icons
• Launcher colours and art, and clock widgets
• Status bar, notification shade, Control Center, volume panel and navigation bar: colours, sizes and icons, including your own signal and Wi-Fi icons
• Theme palette and system colours, or a palette taken from your wallpaper
• Fingerprint icon and unlock animation
• Fonts: a custom .ttf system font, multi-weight fonts, or a font-only theme
• Ringtones, notification and system sounds, and a boot animation (where your system version lets a theme change it)
• Contacts, dialer, Messaging and call screen backgrounds
• Power menu, recents and app backgrounds; hide system UI elements
• Theme details: title, author, designer, description and the theme's texts in other languages
• Presets, undo and redo, before/after views, and store preview images made from your edits


TOOLS

• Theme library on your phone: keep, search, compare and share your themes, and open .mtz files from other apps
• Starter templates (light and dark) to begin a new theme
• Theme checker: finds problems against the official theme rules before you export
• Import your own theme backups (.bak); bought or licensed themes are refused
• Advanced editors: theme files, XML editor, theme keys, resource catalogue and nine-patch editor
• MAML code editor with a live preview


HOW A THEME REACHES YOUR PHONE

1. Open a theme or a starter template and edit the parts you want.
2. Export: the app saves a standard .mtz file in a folder you choose. You can also share it.
3. Install: since Android 11 no normal app may write into the Themes app's folder. The app can install through an optional install helper and guides you through its one-time setup. It is optional; editing and exporting work without it.
4. Apply it in the Themes app.

Please note: the phone may go back to its previous theme after a while. Your edits stay in the .mtz file and you can apply it again. The app tells you this when you install.


FREE AND PRO

• Free with ads. The free version needs an internet connection.
• PRO is a one-time purchase. It removes all ads, works offline, and opens the advanced tools: the advanced editors, lock screen options, the new lock screen builder, always-on display and power menu, MAML code, and combining themes or converting them for another system version. Every other editor stays free.
