I have installed "Find Nearby Accounts" in a sandbox org.  The app is installed and working, somewhat.  Mass Locate Accounts is giving me problems.  I have just over 3000 accounts.  The "Mass Locate Accounts" tab keeps telling me I've exceeded the number of API call's for a 24 hour period.  If I restart the "Mass Locate Accounts" function, it starts again, but eventually I get the same error.  Not sure if this is a sandbox issue, or will be an issue in prod as well.  Anyone else having this problem?
