Tours can be personally built by adding attractions to a list that you can rearrange, and the app will walk you to each one; you can also use one of the packaged tours. There are four tours built into the app; the Dino tour and the Earth and Space tour are preset, but if you're strapped for time, the Highlights tour gives you the choice of a tour that is short, medium, or long with varying numbers of exhibits in each. The Night at the Museum tour shows you exhibits that were featured in the popular film. There is also the option to go on a treasure hunt, which will give you some information on an exhibit and provide hints until you hunt it down.
Floor maps can be displayed with your location pinpointed to allow you to orient yourself. I've gotten lost in the AMNH more than once, and this is quite valuable. An easy to follow orientation video that is subtitled for the deaf is also included in the app.
If you haven't brought the app to the museum, they will lend you a device for free during your visit; I think that's very nice indeed. If you've ever been to the AMNH, you know how daunting finding an exhibit can be. This app solves that problem, and it does a lot more. Since some of the functions can only be done at the AMNH, I can't wait to get there and try it out on-site. I'm sure that using it will make anyone's visit much more enjoyable.
