Lift App app for iPhone and iPad
With the LIFT app you can request or accept a lift in Denmark. All you have to do is to create a user and you are ready. The LIFT app makes it possible for you to get or to give a lift no matter where you are. You can always change your status and become passenger instead of driver or vice versa.
Application would pick your current location and let you now the current location of the driver as well. You can set your status as Passenger if you need Lift and Driver if you provide Lift.
Note: Continued use of GPS running in the background can dramatically decrease battery life.
