What it does
- Shows free and used storage at a glance, plus how much it grew over the last days.
- Finds duplicates, old screenshots, old downloads, and large files you forgot about.
- Clears app caches app by app. On some phones it taps the button for you; where the system keeps that button out of reach, it opens each storage screen and steps aside so you tap it yourself. Cacher checks your phone and tells you which one it is.
- Deep clean removes empty folders, leftovers of uninstalled apps, stale APK installers, and system litter.
- Lists apps you have not opened for months, so you can decide what to uninstall.
- Runs on Android 10 and newer. What the platform does not allow on your version is shown greyed out with the reason, not quietly missing.
