Why Choose a Native Desktop Time Tracker Over Web Apps?
Most modern time trackers are heavy, browser-based tools that slow down your workflow and clutter your tabs. If your browser crashes or your session times out, you risk losing focus and data.
Chronum is built differently. Our Tauri-based architecture delivers the performance of a native application with a minimal memory footprint. It's a local-first tool at its core—the UI stays snappy and responsive because it's powered by your machine's hardware, not a remote server.
Whether you are billing in multiple currencies or generating complex invoices, Chronum handles your data with the precision and speed that only a desktop-first app can provide.
Navigate at the Speed of Thought
Use the Command Dialog (⌘K / Ctrl+K) to start timers, switch projects, or find invoices without touching your mouse. It's the ultimate tool for keyboard-centric power users who value their flow.

Real-Time Reliability
Don't let your tools get in the way. Chronum handles data reconciliation in the background, ensuring that a timer started on your Mac is instantly visible on your web dashboard or Windows machine.
