A highly-regarded database app for tracking player stats, though some users note annoying ads and technical issues with needing to reinstall.

If you are referring to a different type of file (e.g., a PC trainer or skin), please provide more details! To make sure I'm giving you the right information, is this: A app? A PC/emulator mod or file? A trainer/cheat tool?

If you can tell me where you found it or what it does, I can find the specific reviews you're looking for. RenderZ: FC Mobile 25 Database - App Store - Apple
