Cleeen

About

Cleeen is a free, native macOS disk cleaner that helps you clean up storage and see how much recoverable disk space you can reclaim. It uses incremental scanning and includes storage usage and cleanup tools.

Beyond cleanup, Cleeen includes a few small system utilities built around the developer's own needs. Its main extra feature checks Bluetooth device battery levels, such as trackpads and keyboards, and lets you set custom low-battery notifications. This fills a gap in macOS, which only alerts you about the Mac's own battery below 10%, not connected Bluetooth accessories.

Cleeen is free to download for Mac and requires macOS 15 or later. It was created by Zayn Hao, a software developer who cares about design and products. The developer notes there aren't many advanced features yet but may add more later.
