Last week I reviewed National Park Maps HD, an excellent app that offers trail and guide maps to 15 of the most popular U.S. National Parks. If there's one thing more I wanted in that app, it was photos of some of the cool sights available, like the Grand Tetons at dusk. As Apple says, though, there's an app for that, too, and oh boy, is it ever a gorgeous, joyful delight. Warning: I'm going to gush in this review because this app -- Fotopedia National Parks by Fotonauts -- flat out deserves it.
