A cross-platform desktop application for cleaning up system junk files and freeing up disk space.

Clean predefined system files and folders with a single click:

• Scans configured directories for common junk files
• Groups items by category (cache, logs, derived data, etc.)
• Shows total size of reclaimable space
• Displays human-readable names for system folders (e.g., Xcode simulators)
• Allows selective deletion of items or entire groups

Analyze and clean any directory on your system:

• Choose any folder to scan
• Visual pie chart showing space distribution
• Navigate through directory tree
• View detailed size information for each subdirectory
• Delete specific folders or files

Track your cleaning progress:

• Total space cleaned
• Number of items deleted
• Reset statistics

• macOS - Full support with macOS-specific optimizations
• Windows - Supported with PowerShell integration
• Linux - Supported with standard Unix tools

• Xcode simulator cleanup with device names (e.g., "iPhone 15 Pro (iOS 17.0)")
• Xcode DerivedData cleanup
• iOS device support logs
• CocoaPods cache
• Open in Finder integration

• PowerShell-based directory scanning
• Open in Explorer integration

• Fast directory scanning with du command
• xdg-open file manager integration

The Simple Cleaner uses a YAML configuration file (config.yaml) to define cleanable items for each platform. You can customize which directories and files to scan.

• Kotlin Multiplatform - Cross-platform application logic
• Compose Multiplatform - Modern UI framework
• Coroutines - Asynchronous operations
• Material Design 3 - Clean and modern interface

# Run the application
./gradlew run

# Generate installers for your current platform
./gradlew packageDistributionForCurrentOS

# Platform-specific installers
./gradlew packageDmg    # macOS
./gradlew packageMsi    # Windows
./gradlew packageDeb    # Linux

The generated installers will be available in composeApp/build/compose/binaries/main/.

For macOS distribution with code signing and notarization, you need to set the following environment variables:

• SIGNING_IDENTITY - Your Apple Developer certificate identity (e.g., "Developer ID Application: Your Name (TEAM_ID)")
• NOTARIZATION_APPLE_ID - Your Apple ID email address
• NOTARIZATION_TEAM_ID - Your Apple Developer Team ID
• NOTARIZATION_PASSWORD - App-specific password for notarization (generate at appleid.apple.com)
