The first screen is a sign-in display. It also has a “remember me” option to make it faster to use while on the fly. Note that we include a “Do not use while driving” message as a reminder for users to prioritize safety while using our application. Jane enters her email and password that she previously set up online.

Once Jane signs in, the main screen shown above is automatically displayed. At the top, there is a countdown to Jane's next driving time. Below this notification, Jane sees buttons to access the three most relevant tasks, “get map”, “I can’t make it,” and “View Carpool Arrangements.”

Jane presses the “Get map” button, which pulls up a list of directions to aid Jane in navigating her carpool route. For example, suppose Jane needs to drive to Jake’s house and then to Ashley’s house before driving to basket weaving. In this example, the options displayed would include “Route to Jake’s House,” “from Jake's House to Ashley's House,” and “from Ashley's House to Basket Weaving”. We would also have a “reverse” button at the bottom for getting back. The forward/reverse direction would have its default route display based on the current time.

Jane can also press the “View Carpool Arrangements,” which shows the person who is responsable for driving next time, followed by the full schedule.

However, since Jane needs to stay home with Steve today, she needs to inform the other members of her carpool in order to find a replacement. She returns to the home screen to press the "I can't make it" button. The “I can’t make it” button displays different options to inform the carpool members. Jane can then use the app to call, text, or email the members about the time conflict.
