Coverage: this app makes available more than 69,000 maps covering the United States, including Alaska, Hawaii, Puerto Rico and the U.S. Virgin Islands, and now also Canada.
The Maps: these USGS and NRCan maps are the definitive resource for hikers and other backcountry users, and the scans used by this app are of the highest quality. You can make the terrain stand out with hill shading, using simulated sunlight from the direction of your choice.
Downloading: US maps are around 8 MB in size and download in around 10 seconds to 2 minutes on a typical home broadband connection. About 15% of maps then require a 3-minute installation process. Canadian maps are larger. Both cellular data and WiFi can be used, though WiFi is likely to be more reliable in most cases. Please get in touch if you encounter problems while downloading maps.

We have many ideas for additional features to add to future versions of this app; if you have ideas or other questions or comments, contact details can be found on the website, http://topomapsapp.com/. The website also has more screenshots and other information.
App store reviews claiming that the maps date from the 1920s are written by confused users: 1927 is the year in which the standard North American Datum was established, not when the maps were surveyed. If you believe that a newer version of a map is available, please get in touch so that we can fix it.
Note that the 17+ rating is only because the app's help screen could be abused to get uncensored internet access.
This update adds support for the compass (iPad, iPhone 4 and iPhone 3GS running iOS 4 only), and improves the alignment of adjacent maps at different scales. It also makes map display faster on the iPhone 4 and fixes assorted minor bugs.
