Sep 02, 2013 - Ascent Applications today introduces Tandem Parking 1.0 free for iOS, an app that streamlines the process of roommates sharing a single parking space. When users are on their way home, one tap sends an alert to a selected roommate. If accepted, the GPS-based app automatically sends another alert when the user is almost home. This allows roommates to pull their car out and immediately park behind users after they arrive. The app eliminates the need for dangerous calling or texting while driving.
