There are NO Cleaner apps, which will work on an iOS based device (iPhone/iPad). If you need to clear out space on an iPhone, you need to delete things you don't need or use.

None. Let the system do the cleaning. Other tools are simply gimmicks to make you think you need to buy them and can even cause harm.
