All the rave reviews made me choose to buy this app, and we were not disappointed. It was VERY helpful. We would have parked in several dangerous spots, or missed a great site to see, if it weren’t for this app. It would let us know ahead of time, that the parking was 100 yards PAST the waterfall or arboretum. That was critical information. We agree about it’s must see spots. We followed suggestions to start out before 8 (7:20 from Kihei), we hit the must sees and a few others that sounded interesting to us, went all the way to Haleakala for the pools at O’hei and the pipiwei Trail, and we got back to Kihei just after dark. Only improvement I would suggest to the developers is to let us zoom out on the map and select arrows to listen to further ahead if we want. Because the map kept updating, you could only zoom out for 1 sec, often not long enough to check out what you wanted to. It’s also unclear to me why the app shuts off every time you use another app. We didn’t realize it did this until we nearly missed one site. But even with those annoyances it’s a really really great app. Be sure to download it over wifi, because it is large enough to insist upon that. And wifi was not available where we were staying. So I recommend downloading it before you leave home. Then the app is able to run following your GPS, even when you have NO cell service, which is most of the drive.
