I have so many useless apps, I question why I bother keeping them. Sitting at the airport in Kauai after a week here and this app came in handy all over this island. This may be the most useful app I have ever downloaded to iPhone and I have a gazillion apps. If you are going to Kauai, this app is a must.
While the restaurants can be subjective (but a lot of reviews were spot on), when you need to find something in the area you are located this app will help you. It worked almost everywhere on the island in terms of locating you and even without reception you can still use the app.
