Bartopia is a smartphone application that aims to solve the hassles of the nightlife experience. Currently, Bartopia is only available in Waterloo, Ontario and offers the sole feature of "line length". This feature conveys the length of lines at bars and clubs to users. Users will be updated on the length of lines every 15 minutes between the hours of 9pm and 12:45am Tuesday through Sunday. Users must understand this application is based upon the perceptions of a surveillance team and therefore line lengths are only estimations. Click on the play button in the bottom left corner of the application and then click on one of many Waterloo bars in order to identify the length of the line to enter the bar.
