This app was very useful on the way to Hana. It would have been very difficult to choose where to stop given the myriad options. This app concisely gives you your options and just the right amount of guidance. The history on the way back is told in an engaging way, with pauses so you can discuss with your car mates. One thing I will say: I think he intentionally glosses over the violence wrought upon native Hawaiians by Europeans and Americans. He calls the behavior of the Native Hawaiians “adulterous” (imposing rigid, Victorian mores on an entire society without proper contextual info). He also does not spend enough time on how schools and churches were an instrument of racism. The fact that Hawaiians were prohibited from speaking Hawaiian at schools gets a very brief mention.
