The mission of FrontlineSMS:Medic is to advance healthcare networks in under served communities using innovative, appropriate mobile technologies. The centerpiece of our system is FrontlineSMS, a free, open-source software platform that enables large-scale, two-way text messaging using only a laptop, a GSM modem, and inexpensive cell phones. We are also extending the FrontlineSMS platform to enable better patient management, electronic medical records via the cell phone, cheap mobile diagnostics, and mapping of health services.
