Does the find my iphone app help if you lost your phone in your house?

I misplaced my iphone two days ago and i have literally looked everywhere. I know the find my iphone app can help you locate where it is if someone stole it or something but what if you just misplaced it at home?

Yea it does you can use it to make your iphone produce a fairly loud sound so it could be helpfull even when it's in silent mode. I hope you understand what i'm trying to say cause my english isn't that good.

YES. Most of these apps like the apple cloud app and the app Lookout have a 'SCREAM' function that will make your device sound a loud alert. Only downfall is your phone must atleast be powered on.
Highly recommend Lookout. I've had it for years and it is the best and its free. Also runs anti virus functions to protect the device. Will scan every app before download to ensure it is a safe app etc.
