Starting from scratch, this app was created on a hackathon over night in only 14 hours time.
It communicates wirelessly with an OBD-II dongle and automatically pushes a notification on your wrist when you are in range of your car. If the app is started by the user, the car automatically adjusts the position of the mirrors and the seat to match the current user's profile. From the main menu the user can lock/unlock the car and even run a full diagnosis with a single tap.
The app has nothing to do with the carsharing company DriveNow - it is just a dummy name for our app.
