Topos2Go allows you to view and locate your position on topographic maps. You can download freely available maps and store them on your device for use without WiFi or cell access. To try before you buy see Topos2Go Free.

Topos2Go was developed with backcountry hiking and backpacking in mind. Unlike mapping apps that simply cache map data, Topos2Go gives you full control over the maps that are stored on your device. You select the maps you want on your device and they stay there until you delete them. You have no worries about whether or not your cached data will still be there when you look for it in the backcountry.

Features include:

+ Locate your current position on high quality topo maps

+ Maps stored on your device for use without WiFi or cell access

+ Maps sorted by their distance from you making it easy to find the right map for your current location

+ Ability to create and edit waypoints

+ Import and export waypoints

+ Integration with TopoQuest's site making it easy to locate high quality USGS topo maps including finding maps near your current position and maps near other maps in your library

+ Ability to load your own maps on your device

Map Availability: Topos2Go's primary source of maps is TopoQuest which provides extensive coverage of the US with high quality USGS topo maps. You can also direct Topos2Go to other sites with maps. Try Topos2Go Free to see if this app fits your map needs.

Map Compatibility: Currently, Topos2Go supports maps in GeoTIFF format with UTM and Albers Equal-Area Conic projections. If there is an unsupported GeoTIFF map you wish to use, please contact support@cynicsoftware.com and request its inclusion.

Nifty app for the hiker

I really don't understand the complaints about this app. Loading maps from the Mac is really, really easy. Loading from the device is even easier.

That said, I love how easy it is to use. I find it does crash if low on memory when going back to the library from the map though. Not sure what can be done though because the tiff images are huge! I am running this in the 3G. May not happen on the 3GS because it has more memory.

I look forward to running it through the paces on my hike to Trinity Peak here in Idaho.

Sipsey Wilderness

I recently bought a download a coulée maps. We took a weekend backpacking trip to th Sipsey Wilderness in AL. Except for a few spots with heavy canopy in low areas, it worked great. I had a map with a few more details than the USGS maps. The "current location" markings match the extra map and visual surroundings accurately. As always, you should have a paper copy and compass - batteries eventually die!!!

4/5 stars

Had this app for a year

For 2.99 this may be the best topo app for the price. I've used it many times in the wilderness out of cell range without any real problems. Sometimes the GPS gets confused and takes a min to show your exact locations. That's the 3GS's fault though, not the apps. The one downside to this app appears to be the lack of further features/updates. No updates in a year :-(
