A mobile device application for measuring actual wait times experienced by patients of doctors or other medical service providers. A patient launches the application on the mobile device, views available service providers and selects a provider. The patient starts the clock for the selected service provider when the wait begins, and stops the clock when the wait ends. At this time or after the visit, the patient can post their actual wait time, a star-based rating and comments for other patients to view on the application or on a web page equivalent. The patient must be within a GPS-verified geofence around the provider's office in order for the wait time to be considered valid. An integrated real-time messaging application used during surgical procedures is also disclosed.
