Diskzy vs Sensei: an honest comparison
Sensei from Cindori is a system performance tool for the Mac. Its site describes a status bar monitor for CPU, GPU, battery and storage, a thermal dashboard with temperature sensors and fan speeds, battery and drive health reports, a disk benchmark and a Trim switch for SSDs, alongside a cleaner for caches, logs, large downloads and leftover files, and an app uninstaller. It supports Intel and Apple silicon Macs.
Diskzy does much less in breadth and more in depth on one subject, disk space. It has no monitoring, benchmarks or hardware reports. It maps the whole disk, explains System Data part by part, lists what to clean with a reason for each item, and uninstalls apps with their leftovers. Everything it removes goes to the Trash.
