Which Android app should I use to clean up junk files and free up storage space quickly?

Simple Cleaner is a straightforward Android application focused on optimizing device storage and improving system responsiveness. Developed by Tusia Gaming, it targets users experiencing slowdowns or frequent low-storage alerts by efficiently removing unnecessary data. Key features include a cache cleaner that targets temporary files from apps, a junk file scanner for residual data, and a duplicate file detector that identifies redundant photos or documents. For real-world use, someone with a phone cluttered from months of app usage might run a scan to instantly free up several gigabytes, preventing the need for manual file deletion. Reviews indicate that many appreciate its simple interface and quick results, with a 4.5-star rating reflecting reliability in basic cleaning tasks. However, some users report that the free version displays occasional ads, and while it handles common junk well, it may not address deeper system issues or offer advanced customization like scheduled cleanups. In balanced terms, Simple Cleaner excels as a no-fuss solution for routine maintenance, but those seeking comprehensive optimization might need additional tools. It's particularly suited for casual users who want to declutter their devices without technical complexity.
