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 “How much runway does SystemZen have?” 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.

DeviceBeat brings your device activity into one clear dashboard, with native layouts for iPhone and iPad. MONITOR YOUR DEVICE • CPU activity and processor information • Memory usage and available storage • Network traffic, connection details and optional latency checks • Battery level, charging state, thermal state and Low Power Mode • Local history, trends and configurable alerts KEEP KEY READINGS CLOSE Add small, medium or large Home Screen widgets. Customize a compact monitoring panel and use the floating window to follow device activity while working in another app. PRIVATE BY DESIGN No account, advertising or analytics SDKs. Measurements and history stay on your device. The optional network latency probe is off by default; when enabled, it opens a TCP connection to captive.apple.com without uploading measurements. Available readings depend on the device and iOS permissions. Detailed process lists, battery health and cycle count, fan speeds and hardware temperature sensors are not exposed on iOS. Unavailable readings are explicitly marked. Widget refresh timing is controlled by iOS.

Verdict
The clearest difference is in-app purchases: DeviceBeat at none against SystemZen's 2. DeviceBeat also leads on ads (none vs shown). On price, device support and iOS requirement there is nothing between them.
