The doctor app is a medical assistance tool that can save a life in emergency situation. It works on Windows Phone and uses Cortana to launch the app and communicate with you, hands free, throughout the trauma. It will work without network or cellular connection on remote roads, in the Alps, anywhere you might need help. It will call 911 while providing you with the instructions on how to administer CPR or other emergency procedures.
The App is activated by voice through Cortana, ex: "Doctor, (s)he is not breathing"
