Key Customizations & Features

- Redesigned Material 3 player UI
A rebuilt Now Playing screen with artwork-themed Material You tonal controls:
A pill-shaped Play/Pause button and circular previous/next transport buttons.
A squiggly/wavy progress bar with a draggable scrubber.
A compact bottom action bar for queue, sleep timer, shuffle, lyrics, repeat, share, and favourite.
Colours extracted from the current cover art, with smooth crossfades on every track change.

- Dynamic cover-art Material 3 theme
A theme option alongside System, Light, and Dark, enabled by default. UMtify reads the dominant and accent colours of the current cover and builds a complete Material 3 tonal palette from them — primary, secondary, tertiary, surfaces, and every container role. The whole app moves with the music, and the palette crossfades smoothly when the track changes. The feature respects the Reduce animation setting.

- Dual cover art modes
The Full-screen cover art setting switches between two presentations without leaving the player:
On — edge-to-edge artwork that reaches the top and side edges of the screen and fades smoothly into the controls below.
Off — an enlarged floating rounded-square photocard that fills nearly the full width of the phone.

- Clean "Stats for Nerds" badge
Audio details are shown in a compact glassmorphic pill directly below the cover art, styled as a centered Material 3 badge with a translucent artwork-tinted background, a hairline border, an equalizer icon, and monospace typography. It reports the active codec, bitrate, and sample rate, plus Automix analysis status when that feature is enabled. The badge can be toggled in Settings.

- Lightweight and optimized (arm64-v8a)
Built for arm64-v8a Android devices only, keeping the release APK small.
Unused multiplatform modules removed, including Desktop, Web, TV, and native CMake targets.
Background remote update checks and update popups disabled for a faster, distraction-free experience.
Every build is signed with the same committed key, so new APKs install over older ones without uninstalling.
Version codes follow the GitHub Actions run number, so updates always move forward.

- Core playback
High-quality streaming
Synced lyrics
Local music playback
Sleep timer
Queue management

Doppel continues XPrivacyLua by Marcel Bokhorst (M66B), which is not maintained anymore, with a new interface, updates for current Android versions and new restrictions, under the same license, the GPL version 3.

A doppelgänger is a person's ghostly twin: it looks like you, answers like you, and isn't you. When an app asks for your location, contacts or device ID, your double answers in your place: the answers look real, but the app learns nothing true about you.

Features
- Apps: restrict any user or system app by group or by single hook; swipe an app for Restrict all, Remove all and its groups, with Undo
- Fake values for all apps or per app, like the IMEI, Android ID, location and time zone; the identifiers can be new each boot, a different one for each app, so apps cannot follow you across apps or restarts
- Activity: what each app tried, with the real and the fake value, and hook errors
- Hooks: view, edit, import and export hook definitions, add your own and install definitions shared by others with Downloads, like a domain blocklist
- Settings: backup and restore, restricting new apps, collections, theme, accent color, pure black background and app icon
- Multi-user support, free and open source
