It’s a GPS driven app with stops, history, sights, restaurants food trucks turn by turn and is excellent. We used it on three islands. This is the best of the digital world and internet. I wish I knew of other apps like this in other destinations outside of Hawaii. We were there for four years and used all of the tours. They are excellent, you can start them and stop them at will, get off the tour and then return to it, obviously there are minor glitches with coordinating it, but overall it was excellent
