Automatically collect and visualize usage statistics in Ubuntu/OSX
...Users can add notes to specific moments or summarize an entire day for additional context. Everything is stored and processed locally rather than uploaded to a remote service. Its browser interface is built with HTML, CSS, JavaScript, and D3 and supports both daily and overview views. Activity titles can be normalized through configurable matching rules to make reports easier to read. The original implementation targets Ubuntu and macOS and is best viewed as an experimental personal productivity tracker.
