UNOShuttleTracker is awesome for knowing how to plan my day around UNO without taking my car everywhere. This helps me save gas and a possible ticket. So, the apps purpose is great.
However, the way UNOShuttleTracker is integrated is pretty poor. The use of a web interface throughout is asking for some sort of incompatibility down the line. Native use of iOS's programming would significantly improve the look and responsiveness of UNOShuttleTracker overall. Also, for bonus points, integrate the shuttle tracker into the existing UNO app!! I don't know about others, but I hate when I need to download more than one thing and have another icon on my phone, especially if they are from the same organization. A one-stop shop style app would not only be more convenient, but look more professional in my opinion. The only reason for my star rating is really just the implementation of the idea rather than the concept.
