MedTrack is an application that helps doctors send more complex information, as well as time-delayed instructions, to their patients. It helps make their expertise much more accessible to their patients. Doctors can set up reminders for things like follow-up appointments, medicine instructions, or when/where to refill their medications, and their patients will receive them via SMS. We also make it easy for patients to find doctors near them, using the same SMS system. Future additions include adding the ability for doctors to leave voice messages, to accommodate patients who are not able to read and write.
