We purchased this app to tour around Oahu. The driving directions and tips were clear and very timely. We honestly would have driven right by some of the most beautiful and memorable spots had our tour guide not told us that these were "no miss" sights. It was brilliant and quite entertaining. A fellow tourist poolside at our hotel bragged to me that they got a great deal ($179 for four) for an excursion to the USS Memorial. She quickly changed the subject when I told her we toured the entire Island and learned and saw so much for just $6.99 - the cost of downloading the app! Id definitely purchase it again when touring other locations.
