is there an app out there where you can put on someone’s phone to track their whereabouts without them knowing
What are you experiencing?
I’m going to assume you suspect somebody else may have done this to you.
I’ll further assume that attempting to remediate this situation will not place you at immediate risk of harm.

If your iPhone has potentially been compromised, I’d perform a factory reset without restore, would change all passwords and passcodes, and would run Safety Check.
Start here: If you think your Apple Account has been compromised - Apple Support
The reset: Restore your iPhone, iPad, or iPod to factory settings using a computer - Apple Support
You can re-download apps you have purchased, and iCloud data and photos and mail will remain available.
