On the big island of Hawaii now using BigIslandHawaiiTourGuide. It has been easy to set up (in a rental, no less), extremely user friendly, really educational, and your guide, Mr. Shaka is just downright fun to listen to. Gps is on point and takes you off the beaten path to really cool hidden spots as well as popular spots. Just pick one of their tours and head out for the day. That’s what we did, and hubby and I both agree, this is one of the best apps out there. Oh and, I splurged and bought the $9.99 option which gives you about 5 different tours on the big island alone. You have the option to purchase each adventure by itself but seeing we were going to be here for 1 week, it made sense to get the bigger one. Great deal. Worth every penny. Spend the money. You will love it! Make more of these apps please!!
