Hi there, Juneboy3.
Thanks for using Apple Support Communities! I see that your iPhone won't stop chiming after using the Find iPhone app. That would drive me to distraction and I'll be glad to help.
Find My iPhone: Play a sound
Force an app to close on your iPhone, iPad, or iPod touch -- Use the information in this article to force the Find iPhone application to close.
Restart your iPhone, iPad, or iPod touch -- If you couldn't locate the Find iPhone app in the multi-task list, restart your phone. The shutdown and startup processes are important to keep the iOS software running properly.
Let me know how that goes and take care!
