A privacy-first screen time tracking application for Linux with a polished terminal-based user interface (TUI). Mono runs silently in the background to track your application usage while providing a beautiful, htop-inspired dashboard for visualization.
- Privacy-First: All data stored locally in SQLite, never leaves your machine
- TUI Dashboard: Beautiful terminal interface inspired by htop, btop, and lazygit
- Background Tracking: Runs as a daemon on system startup
- Real-Time Updates: Live tracking of active applications
- Weekly Overview: Visual bar chart of daily screen time
- Application Stats: Detailed breakdown of time spent per application
- Hyprland Support: Integrated with Hyprland window manager
- Linux only (tested on Arch Linux with Hyprland)
- Rust 1.70 or later
- Cargo (included with Rust)
- SQLite (bundled with the application)
- Hyprland (optional, for window title tracking)

./install.shThe install script builds the release binary, installs it to ~/.local/bin/mono-tracker, and sets up autostart via systemd (with XDG autostart as fallback).

On first launch, Mono displays a consent prompt:
- Enable Tracking: Starts the daemon and enables autostart
- Skip for Now: Opens dashboard without tracking
