Overview
Llamafin runs on four distinct platforms — Web, Android, iOS, and Desktop (Windows/macOS/Linux) — using a single codebase that adapts its behaviour to each platform's unique capabilities and limitations.
Why It Matters
Rather than maintaining four separate apps, Llamafin uses a unified approach:
- Consistent Features: Every platform gets the same core functionality
- Platform-Specific Optimizations: Each platform gets tailored performance settings
- Native Integration: Mobile and desktop versions access device hardware (haptics, audio outputs, file system)
- Simplified Updates: A single code change improves all platforms simultaneously
Platform Architecture
All platforms share the same Angular 16 web application, but each adds a different "wrapper":
| Platform | Wrapper | What It Adds |
|---|---|---|
| Web | None (runs in browser) | Nothing — pure web app |
| Android | Capacitor 5 | Native APIs (haptics, file system, status bar, share) |
| iOS | Capacitor 5 | Native APIs (haptics, file system, status bar, share) |
| Desktop | Electron 25 | Node.js runtime, native window management, system audio device access |
Supported Platforms

How Platform Detection Works
When the app starts, it detects which platform it's running on and configures itself accordingly.
Detection Process

Mobile Experience
Android
Key Adaptations:
| Feature | Behaviour |
|---|---|
| Status Bar | Hidden completely for immersive experience. Content renders edge-to-edge behind the status bar area. |
| Back Button | Hardware back button handled by Angular router (not Ionic's swipe gesture). Swipe-to-go-back is disabled. |
| Keyboard | When the keyboard appears, the app automatically resizes to keep input fields visible. |
| Performance | On first install, the app automatically applies performance-optimised settings (lower frame rates, fewer visual effects) to ensure smooth playback on mobile hardware. This happens once and is never repeated. |
| Haptics | Tactile feedback on button taps, modal interactions, seekbar drags, and multi-select operations. Can be disabled in settings. |
| File Storage | Requires read/write storage permission. Permission is checked at startup and re-checked when the app returns from background. |
| Sharing | Uses Android's native share sheet (same as any other app). |
Android Permissions Requested:
- Internet (for streaming)
- Read/Write External Storage (for downloads)
- Wake Lock (to prevent screen sleeping during playback)
- Foreground/Background Service (for background playback and downloads)
iOS
Key Adaptations:
| Feature | Behaviour |
|---|---|
| Status Bar | Hidden completely for immersive experience. Content renders edge-to-edge. |
| Home Indicator | Safe area padding automatically applied on devices with home indicators (iPhone X and later). |
| Camera Notch | Automatic padding compensation for notch and Dynamic Island on supported devices. |
| Keyboard | Same as Android — app resizes to keep input visible. |
| Performance | Same as Android — automatic performance optimisation on first install. |
| Haptics | Same as Android — uses Apple's Taptic Engine for precise feedback. |
| File Storage | Uses iOS sandboxed file system. Files stored in app's Documents directory. |
| Sharing | Uses iOS native share sheet (AirDrop, Messages, etc.). |
| CarPlay | Lock screen controls and CarPlay integration via Media Session plugin. |
iPhone Only: The app is optimised for iPhone. iPad users can run it in compatibility mode (2x phone size) but it is not natively optimised for tablet screens.
Mobile Performance Settings
On first install, the app automatically applies these optimizations to mobile devices:
| Setting | Desktop Default | Mobile optimisation | Why |
|---|---|---|---|
| Spectrum Visualizer | High preset (60 FPS) | Low preset (15 FPS, 16 bars) | Saves battery and CPU |
| EQ Faders | High fidelity | Low preset (100ms throttle) | Reduces rendering load |
| Rotary Dial | Animated | Static/low | Fewer animations |
| Download Performance | High | Low | Prevents network congestion |
| Visualisations FPS | 60 FPS | 25 FPS | Smooth but efficient |
| Text Overflow | Marquee (scrolling) | Truncated (static) | Less CPU for text animation |
| Turntable Animation | Full detail | Power saver | Reduces GPU load |
These settings are applied ONCE and never changed again. Users can manually override them in Settings → Appearance.
Desktop Experience
Electron Desktop App
The desktop version wraps the web app in a native window with additional capabilities.
Window Management
| Feature | Behaviour |
|---|---|
| Default Size | 268 × 513 pixels (compact music player size, similar to Plexamp) |
| Expanded Size | 412 × 660 pixels (full player with Visualisations) |
| Frameless | No title bar or borders — custom UI handles all window controls |
| Always on Top | Stays visible above other windows by default |
| Not Resizable | Size changes only through player controls (not manual drag) |
| Not Maximizable | Designed for compact size, not fullscreen |
| Closable | Can be closed like any window |
Window Controls
The app provides custom buttons for:
- Shrink: Reduces to compact size (268×513)
- Expand: Expands to full player (412×660)
- Toggle Fullscreen: Enters/exits fullscreen mode
- Quit: Exits the application
Audio Device Selection
Unlike mobile (which can only switch between Bluetooth and wired headsets), the desktop app can select any system audio output device:
- Built-in speakers
- Headphones (3.5mm jack)
- USB DACs
- Bluetooth headphones/speakers
- HDMI/DisplayPort audio
- Virtual audio devices
System Tray
When enabled, the app runs in the system tray:
- Icon: Shows app icon in tray/menu bar
- Click: Shows/hides the main window
- Right-Click: Context menu with "Quit App" option
- Background Operation: App continues playing music even when window is closed
Menu Bar
| Platform | Menu Style |
|---|---|
| macOS | Native app menu (About, Services, Hide, Quit) |
| Windows | Basic file menu |
| Linux | Basic file menu |
Desktop-Specific Features

Server Discovery on Web
The web version cannot perform actual mDNS/UDP network discovery (browsers don't have access to these protocols). Instead, it shows mock demo server data to illustrate the feature.
Hardware Integration
Haptics (Mobile Only)
The app provides tactile feedback for 25+ interactions across the interface:
| Interaction | Haptic Style | What It Feels Like |
|---|---|---|
| Button taps | Light | Gentle tap |
| Modal open/close | Medium | Noticeable click |
| Seekbar drag | Medium | Tactile feedback during scrubbing |
| Multi-select | Selection (start/change/end) | Ticking feel during drag select |
| Download start/complete | Heavy | Strong confirmation |
| Settings toggles | Light | Subtle confirmation |
Disable Haptics: Settings → Advanced → Haptics
Audio Output Devices
| Platform | What You Can Select |
|---|---|
| Web | Browser's default output (cannot change from app) |
| Android | Bluetooth devices, wired headsets |
| iOS | Bluetooth devices, wired headsets, AirPlay |
| Desktop | All system audio devices (speakers, headphones, USB DACs, HDMI, virtual devices) |

| Android | /Documents/llama/ (shared storage) | Read/Write External Storage |
| iOS | App's Documents directory (sandboxed) | Implicit (iOS manages) |
| Desktop | User's Documents folder | None (full OS access) |
Permissions & Privacy
Android Permissions
| Permission | Why It's Needed | When It's Requested |
|---|---|---|
| Internet | Stream music from Jellyfin server | Automatically granted at install |
| Read/Write External Storage | Download music for offline listening | Requested when you first try to download |
| Wake Lock | Keep screen on during playback | Automatically granted at install |
| Foreground Service | Play music in background | Automatically granted at install |
iOS Permissions
| Permission | Why It's Needed | When It's Requested |
|---|---|---|
| Local Network | Discover Jellyfin servers on your network | When you open the server discovery page |
| File Sharing | Access downloaded music via iTunes/Finder | Automatically enabled |
Desktop Permissions
The desktop app runs with full user privileges and does not request any additional permissions. It has the same access as any other application on your system.
Permission Denial
If you deny storage permissions on mobile:
- Downloads are blocked with a "Missing Permissions" error
- The app prompts you to enable permissions in system settings
- Streaming and library browsing continue to work normally
Performance Adaptations
Automatic Mobile optimisation
On first install, the app detects that you're on a mobile device (iOS or Android) and automatically applies performance-optimised settings. This ensures smooth playback and long battery life on mobile hardware.
What Changes:
- Fewer visual effects (lower frame rates, simpler animations)
- Truncated text instead of scrolling marquees
- Power-saving mode for the turntable Visualisation
- Reduced download concurrency to prevent network congestion
When It Happens: Only once — the very first time you install the app on a mobile device. A flag is stored to prevent it from running again.
Can I Change It?: Yes. Go to Settings → Appearance to manually adjust any of these settings back to higher quality if your device can handle it.
Desktop vs Mobile Defaults
| Setting | Desktop Default | Mobile Default | Reason |
|---|---|---|---|
| Visualisations FPS | 60 | 25 | Battery life on mobile |
| Spectrum Visualizer | High preset | Low preset | CPU/GPU conservation |
| Text Overflow | Marquee | Truncated | Less CPU overhead |
| Turntable Animation | Full detail | Power saver | GPU conservation |
