Key takeaways
- Clears app cache, residual files and leftover install packages in one pass.
- Reclaimed 2.4 GB on a two-year-old Android test device.
- Scheduled clean-ups make the difference between one-off and useful.
- Cache returns; expect to run it monthly, not once.
Android cache cleaners have a credibility problem, mostly earned: many inflate numbers by counting space the system would have reclaimed anyway. We ran Cleaner Too against a manual audit of Settings > Storage on a mid-range handset to see how the figures compared.
What the scan found
- 1.App cache across 60+ installed apps: 1.6 GB.
- 2.Residual files left by uninstalled apps: 310 MB.
- 3.Leftover APK install packages in Downloads: 420 MB.
- 4.Duplicate files flagged for manual review: 90 MB.
That tracked closely with the manual audit, which is the main thing we look for. The device did not become dramatically faster — no cache cleaner makes a modern phone feel new — but storage pressure eased and the gallery stopped stuttering while scrolling.
Feature list
- App cache and residual file scan.
- Large-file and duplicate detection with manual review.
- Scheduled automatic clean-ups.
- Lightweight footprint with no reboot required.
