What is Nijia?
Nijia is a macOS app that helps you understand what is taking up space on your Mac and what you can safely clean up. It scans storage locally, shows where your gigabytes live, and explains whether files can be rebuilt or should be kept. It also looks at developer workspaces, worktrees, and agent sessions, so you can review code-related storage in one place. On top of that, it can tidy your desktop by grouping files without deleting anything, and it includes a live system watch for disk, memory, and load. New users can try the full feature set free for 7 days. Everything is review-first, so you stay in control before anything moves to Trash.
