I thought there were other features it had besides your current location (blue dot)?  If it is just a wrapper for the current maps, I'll pass.

It actually says that you should be able to purchase district maps through the software, but when I tried it shows them but gives no option to purchase any of the district maps for Mt Hood NF.  Oh well...

I looked into this further, and found that is actually does tracks. And a lot more. This app is really designed and intended for professional mappers but it has a lot of features anyone can use. Their writeup online on most pages almost ignores the track recording, but I finally found this with a clear statement that it does: http://www.avenza.com/pdf-maps# . Other functions likely will only be used by professionals who have access to software that can produce geospatial PDFs, GeoTIFFs or GeoPDFs. Given that, you can produce maps with specialized GPS, GIS and other data which can then be viewed in this app. And that is the real claim to fame for this product. A normal PDF map file will not magically become usable by this app, they do not have the required GIS type data in them. This fact is likely the source for the complaints about this app that are in the app store. The ability to record tracks was added with app version 2.0; its now at 2.1. All the glowing testimonials on their sites are from mapping professionals.

For the rest of us this will measure lines and areas, record waypoints/points of interest, export KLM files for Google Earth, CSV, or GPX files which mean the data can transfer to databases and Excel-compatible spreadsheets, display your current map view in Google Earth (assuming you are on a network) and it appears to have a note taking and photo taking system that will display all that on a map. The maps can be displayed in lower and higher resolution.

Yes, this app also acts as a sales tool for maps. The have an online store with 700,000 maps available, some of which are free and the others start at .99.

I will be testing this and hope to get some custom maps on it to see how it works. More to follow once I get a chance to see how this matches up to the hype.
