The app itself seems as though it has never been upgraded since it first came out. Navigation can be a bit difficult as bus stops are not placed accurately on maps and looking for stops that are not near you can prove to be difficult unless you have the bus stop number. Even with the number, you are sometimes greeted with a message stating that the stop does not exist. Now… those could be easily overlooked if the app is able to consistently do what is promised. Unfortunately, it fails from the early evening onward. All stops pretty much displays that arrival time are not available. This continues well into the evening. The idea started off great but with lack of maintenance and regular improvements to the bus tracking system, it is a failure (for the app developers hired, TheBus, and the Honolulu Office of Transportation).
