No, there's no such thing as spying on a cell phone for free. You need to buy the software and make sure you get it from a trusted source. There are too many scammers out there, and they constantly come up with new name-brand apps that look official but, in reality, have been designed to take your money and give you nothing in return. Don't fall for these trap games when learning how to spy on someone's phone for free! If anyone ever offers you a spy app that doesn't cost anything, just leave immediately.
