Turn your old Android tablet into a beautiful digital photo frame.

OpenPhotoFrame is a free, open-source slideshow app that syncs photos from your private cloud (Nextcloud) or local storage. No ads, no subscriptions, no nag screens – just your photos.

• 🖼️ Beautiful Slideshow – Smooth crossfade transitions between your photos
• ☁️ Nextcloud Sync – Sync photos from a Nextcloud public share link (WebDAV)
• 📁 Local First – Works offline, photos are cached locally
• ⚙️ Simple Settings – Configure slide duration, transition speed, and sync interval
• 🌙 Always On – Designed to run 24/7 as a dedicated photo frame
• 🔒 Privacy First – Your photos stay on your server, no third-party cloud required

Existing apps like Fotoo or PhotoCloud Frame Slideshow are either:

• Riddled with ads and nag screens
• Require paid subscriptions for basic features
• Force you to use public cloud services (Google Photos, etc.)

OpenPhotoFrame is different:

• ✅ 100% Free & Open Source (GPLv3)
• ✅ No ads, no in-app purchases, no tracking
• ✅ Works with your self-hosted Nextcloud
• ✅ Simple & focused – does one thing well (KISS principle)

Coming soon to F-Droid

For now, build from source (see Development section).

flutter run -d linux

• Flutter SDK (3.x)
• Dart SDK

# Clone the repository
git clone https://github.com/micw/OpenPhotoFrame.git
cd OpenPhotoFrame

# Get dependencies
flutter pub get

# Run on Linux (fast iteration)
flutter run -d linux

# Run on connected Android device
flutter run -d <device-id>

To update the app icon, replace assets/icon.png with your new icon (recommended: 1024x1024 PNG), then run:

dart run flutter_launcher_icons
cp assets/icon.png fastlane/metadata/android/en-US/images/icon.png

This generates icons for all platforms (Android, iOS, Web, Windows, macOS, Linux) and updates the F-Droid metadata.

The app follows a Local First architecture with clean separation of concerns:

• Player (UI) – Displays photos from a local directory with smooth transitions
• Syncer (Service) – Downloads photos from cloud sources in the background
• Repository Pattern – Abstracts storage access
• Strategy Pattern – Swappable playlist algorithms (random, weighted freshness)

Tap the center of the screen during slideshow to open settings:

If typing the Nextcloud URL on a tablet is cumbersome, you can paste it via ADB:

# Focus the URL input field on the tablet, then run:
adb shell input text 'https://cloud.example.com/s/YOUR_SHARE_TOKEN'

Some Android devices (especially Huawei with EMUI) don't allow disabling the lock screen in the settings UI. You can disable it via ADB:

adb shell locksettings set-disabled true
