"Best EVER hands DOWN Update: SUCH a worthy app, I went ahead and paid for the ad free version just to show my support for the dev and their excellent work.

You can set it to cycle every 6 minutes, making it as idiot proof as you can imagine - even if you are an idiot! You can't pay ME to get RID of this app!" -- by Kori Weiser

Q: How clean cache?
A: It's quite easy, just open app cache cleaner and tap the clean button, and it will clear cache for your phone.
Q: What is cached file?
A: A cached file is a mechanism for the temporary storage (caching) of web documents, such as HTML pages and images, to reduce bandwidth usage, server load, and perceived lag. A cached file stores copies of documents passing through it; subsequent requests may be satisfied from the cache if certain conditions are met.
The cached files are stored in the phone built-in memory, and sometimes can take a lot of storage space. Through the clearing of cached files, you are able to recover the precious phone memory space. Most importantly,the cached files can safely be cleared :)

1 What is the cache?
A: Cache is a mechanism of storing data in high-speed memory, speed up application's reading and writing, which improve application performance.
2. Why should clear the cache?
In the android phone, cache files are stored in the phone internal memory (ROM), the phone internal memory is different from the SD card, you can think cache is computer memory and SD card is hard drive, one fast and another slow.
Because the internal phone storage capacity is fixed, if you don't clear in time, the cache will be larger and larger, and finally running out of internal phone storage.
3 Will clear the application's data while clear the cache?
A: The application's data is different with cache, cache is temporary storage of files, used and no longer valid; but application's data will be used later, such as games record and user information.
Clear the cache wont clear the application data, do not worry
Clear the cache wont clear the application of historical data too, such as search history, call records. If you need to clear the historical data, you can use our another application "History Cleaner+"
Cache Cleaner+ is newest and best cache cleaning tool on the market currently, just try it.
