This was definitely worth the cost. You just have to be comfortable driving outside the US because of the different signage.
The tour needs a few tweaks, but we overall were glad to have purchased it over just driving to the different sites. We probably also preferred it over a bus tour since it gave us more flexibility (and a much much lower cost).
The app worked well and the tour itself worked well with the GPS. There were a couple of driving directions that were missing or miss-timed which is why I gave it 4 stars instead of 5.
The tour will be best in the summer so that you have tons of daylight. Spring and fall will be better than winter, but will want to start your journey in the morning, but you don't have enough light. We did it in May and had enough light even into the late hours of the night. Dress warm and have waterproof shoes and a jacket available, especially for the waterfalls!
We skipped a few of the sites, and the tour still took us 8+ hours!
