wherein the second client device is executing a customer version of the application; and

wherein the particular geographic location comprises a retail store.

12. The computer-implemented method of claim 10 , further comprising:

detecting a plurality of mobile devices at the particular geographic location;

generating information for a graphical user interface that when rendered on the first client device through the first version of the application displays a list of customers who are presently located in the particular geographic location based on the detection of the plurality of mobile devices.

13. A computer-implemented method comprising:

periodically broadcasting, by a beacon in a first client device executing a first version of an application, signals directed only to a different, second version of the same application;
