The Line 2 Dine iPhone application allows users to view and submit estimated wait times for popular restaurants in real-time. Users can search wait times from home or in their car as they drive by restaurants. The app utilizes GPS technology to record a user's arrival time and party size when they check-in. It then notifies them when their quoted wait time has passed to see if they have been seated. This provides a more productive way for both diners and restaurants to manage long wait times.
