FYI, there are not multiple 'starting points', but only one starting point. We drove to an alternative starting point to begin the tour, and the first thing it did was...send us to the other starting point! lol Hey, we were in Hawaii, and it was beautiful, but I'd recommend that they make it clearer.
I still give the app 5 stars because even though it was the first Shaka tour we did, we quickly figured out how to maximize the app, and it was very enjoyable. You can go here or there and use it as you like.
Stories are fun, and interesting, and show you things that you'd otherwise miss. Well worth the cost! We ended up getting a second for a different part of the island.
Even if you are vaccinated (as we were), I’d recommend waiting on a trip to Hawaii until the Covid-related mandates are lifted, as they clearly diminished Hawaii’s “Aloha” spirit. Also, be aware that various amenities are missing and mask mandates are extensive, and extend even to the outdoors (truly, and in practice). You absolutely should not go if you are not vaccinated as most businesses will deny you entry.
