Google Directions API query limit

Question

The url http://code.google.com/intl/lv/apis/maps/documentation/directions/ includes the following :-

> Usage Limits Use of the Google Directions API is subject to a query limit of 2,500 directions requests per day.

<<<

Does this apply to a per handset basis (ie each handset is allowed 2,500 directions requests per day) or per app as a whole (ie only 2,500 directions requests per day allowed for that app, regardless of the number of handsets invloved). I know the Premium Service allows 100,000 request, but it is a bit expensive.

Thanks very much in advance

Answer 1

Since the Google Directions API does not require a Google Maps api key then it probably goes by the requestor's IP address, so each individual user has 2500 requests per day.
