Perfect App
Well designed and implemented app. Very detailed information on the park and the sites to see.
When driving, certain pre-defined waypoints trigger the audio. Its also aware of which direction you are traveling on the road. We never had an issue with the app not working in the park and would have missed several stops had we not used this.
If you arent taking a commercial tour you MUST buy this app. Its worth the money.
