We recently used this app while in Oahu for a week. We didnt want to take a circle island tour because with three little kids they needed to go on our own pace. The kids nick named the narrator "Steve" and complained of we had to have "seri" tell us where to go and not Steve. They liked his jokes and my husband thought his navigation was much better than mine! It worked super slick with the GPS. Only drawback is it goes only counter-clockwise around the island. When we were going the other way you just had to manually select what arrows you were near and ignore the driving directions. Best money we spent on this trip!! Well worth the price!
