Great Nature App!

This is a great app for anyone visiting YNP. It has tons of information and pictures of the most interesting things you’ll see in the park. I love how you can keep track of what you’ve seen and make notes. There’s even a ”license plate game” feature!

Decent basic app

This is a decent, basic, no-frills app that provides a good amount of information on Yellowstone National Park and things you’re likely to see. The interface is somewhat clunky looking but works. They do indicate that the app is not a comprehensive guide and that is definitely true but it does give a lot of the most commonly seen wildlife and geothermal features. Hopefully future updates will add many missing mammals as well as a very limited list of birds, wildflowers, and trees. It is worth the 99 cents to get the full feature set.

Great app!

This app has an incredible amount of information, especially for the price! My kids love looking at the animals and learning about them. I would highly recommend this app for anyone visiting Yellowstone.
