SystemZen

SystemZen tells you how long your storage will last, and helps it last longer. STORAGE RUNWAY SystemZen reads free space when it opens and after every scan, and turns those real readings into one number: the days until your disk is full at the pace it is filling. After a scan it shows how many days a cleanup would buy back. While it is still learning your pace, it says so instead of guessing. CLEANUP, MY CLUTTER, SPACE LENS Cleanup clears caches, logs and temporary files. My Clutter finds the files and photos you have twice. Space Lens shows where the space went, folder by folder. PERFORMANCE, INTERNET, PROTECTION CPU, memory and login items on Mac; heat, power mode and refresh on iPhone and iPad. Live network use. The permissions and privacy traces worth a look. SIRI, SHORTCUTS, WIDGET Ask โHow much runway does SystemZen have?โ and the answer comes from your own readings. Start a scan or open any page from Siri, Shortcuts or Spotlight, and keep the Runway widget on your Home Screen. MY ACTIVITY Sign in and every scan and cleanup appears on your Mac, iPhone and iPad. HONEST BY DESIGN Every number comes from your device. Mac cleanups go to the Trash first. Your files are never uploaded. SYSTEMZEN PRO Free includes scans, Runway and a starter cleanup. Pro unlocks unlimited cleanup, duplicate removal, every tool in My Tools, scheduled maintenance and background protection. Try the annual plan free for 7 days.
