Can you use the find your iphone app without iCloud?

I was looking for my iphone within my house, with its ringer off. So I decided I might as well use the "find my iphone app" which I have both installed on my computer and iphone. I google the app, and instead of getting the page to actually locate the phone, I get several webpages of how to set the whole thing up. Now, I finally click on this one page to find my iphone and it says "login to your iCloud account." I don't have an iCloud account. That being said, can I actually used the "find my iphone" app without iCloud? And is there any other way to locate this iphone?

No, you need an iCloud account to use the find my iPhone services

it wouldn't make a difference anyway, the GPS isn't accurate enough to know where it is in your house, it would just show its in your house. Which you already know.

You need icloud active to find the phone with "find my phone".

You needed a iCloud account in order to log in to the "find my iphone" app on your iphone. That means you had to set it up first before using this feature.
