UDERdoc is an application for patients to search and book doctor's appointments online. Two of the basic problems plaguing the Filipino community in regards to healthcare is the lack of information on availability of certain medical specialists, and the hours upon hours of waiting in line at the clinic. In addition to that, doctors themselves deal with certain issues such as lack of patients, mismanaged schedules leading to bottlenecks and long lines, and the difficulty of building prestige in a shorter period of time. All of these problems are addressed by UDERdoc, through efficient and cost-effective marketing and advertising of the doctors and their clinics, easy and convenient use of the application that provides 24/7 online booking of doctor's appointments with guaranteed schedules, and collection of verified feedback and reviews which aims to highlight the services received and rendered by the patients and medical practitioners.
