This paper presents an application titled "Rapid Response Fall Detection System"-RRFD. This application aims to detect when a cyclist has suffer an accident, and alerts the emergency contacts about the accident. "RRFD" uses the cellphone built-in accelerometer for fall detection, and the GPS to provide an accurate location. When a fall is detected, the application sends an alert via text message to previously selected contacts. Any sudden fall will activate the application and send the text with information of whether the rider requires assistance and / or immediate medical help. In the event that the cyclist is unable to request assistance or help, it provides the route and location of the cyclist using various tools of high accuracy.
