What's the best Android app for clearing cache and junk files without being too aggressive?

Cleaner Toolbox is designed for users seeking thorough but controlled device maintenance. The app scans for cache files, residual data, and temporary files that accumulate during normal phone use. Its systematic approach categorizes files by type and size, allowing users to selectively remove content rather than performing bulk deletions. The interface displays exactly what will be deleted before confirmation, preventing accidental removal of important data. For routine maintenance, the one-tap optimization feature can free up RAM and close background processes that may be slowing device performance. However, reviews indicate the notification system can be persistent, with some users reporting frequent prompts suggesting cleaning operations even when storage isn't critically low. The app includes a duplicate file detector that identifies identical photos and documents, plus an app manager for batch uninstallation. While generally effective at reclaiming storage space, occasional users have questioned scan accuracy when results show minimal junk files despite previous heavy usage. The balance between thorough cleaning and notification frequency appears to be the primary consideration for potential users.
