I, too, hardly ever write reviews. I wish I had found this and the more comprehensive general Maui version a long time ago. Having been to the island countless times, I thought I knew a great deal about this wonderful place but learned more about the island in a few hours with this guide than I had in perhaps as much as 200 days spent here. Aside from a scant few painful jokes, the narrator is outstanding. The app functions wonderfully except for the fact that there is no master list of the audio portions such that they can be listened to without clicking on the map itself. There is a preview mode that permits listening to various portions without driving them (constantly updates based on where you are) but a master list would still be useful as well as an accompanying index. Really good app and highly recommend. My complaints could be fixed easily in an update.
