Hikers and climbers can now access real full-resolution USGS topographic 1:24k quads with side-scrolling multi-zoom map capabilities.
In addition, quads can be graphically selected for storage on the device for access where you need it most, away from cellular and WiFi coverage!
Current Map and GPS positions are available in latitude/longitude and UTM coordinate systems. NAD27 and NAD83 are supported.
Available Map Sources:
USGS (United States and borders)
11 Zoom Levels are available to give full resolution quadrangles. Simply pinch to zoom in or out! Get in close for details, or zoom out to see your whole area!
Select quadrangles graphically just by double-tapping! No need to mess with coordinates or obscure quadrangle names.
GNIS (Geographic Names Information Service) database included for Features of Interest lookup. Lookup features (summits, waterfalls, streams, etc) and add them as waypoints! No need to type in waypoints by hand. You can also search the database in an area and it will label all local features. ~700k entries available at the touch of a finger!
All 50 United States States included.
- Full Resolution 1:24k USGS Quads (1:63k in Alaska)
- UTM and latitude/longitude
- Meters and Feet
- NAD27 and NAD83 datums
- Cache maps on your phone!
- Display and record Tracks
- Editable Waypoints - Just tap to place or lookup by name.
- Course and Speed

- Magnetic Declination Calculations
- Map works in portrait and landscape positions!
- GPS Location and Map following
- Look up GNIS locations from geographic formations (like Summits, Streams, Falls, Cliffs, etc) and add them as Waypoints. Have iTopoMaps label neighboring features!
When in Grid Mode, simply double tap an area to select a quad for download! Downloads happen in the background and can be restarted where you left out! Wifi/3G recommended for Quad downloads.
GPS is not required for map usage, but adds to navigation functionality.

Ratings and Reviews
DO NOT WASTE TIME/MONEY ON APP!!
As an avid backpacker, maps are my best friend (& GPS).I was intrigued enough by this temptation that I bought it notwithstanding the chorus of negative reviews.
LEARN FROM OTHERS MISTAKES!! Move away from this "MIS-APP." It is useless unless you want only a birds eye view from 30,000'. The app WON'T: 1) zoom in; 2) might download 1 or 2 quads if app is given equal # days dedicated time (but see 1, you can't zoom in on a downloaded quad; 3) provide any way to contact developer for fix; & 4) if app has navigational tools as advertised, they're professionally hidden. Determined to crack this app, I wasted hours & hours on this "c-rap."
Please learn from the mistake of an outdoorsman of 45+ years whose tried every navigational tool on 45 yrs. of markets: don't give away a dime to this so-called "developer."
Back in 2010 this was a good app. I don't know what has happened since, but it has been worse than just languishing. The app has been crashing for a couple of years and device upgrades (at least). It has now been rendered worthless from the iPhone 4s through iPhone 6+ and iPads in between (read: not device related).
The maps (quads) download about as fast as the U.S. Congress works. But that really doesn't matter since the app crashes upon open after that. There used to be a safe mode switch (they evidently knew their device was failing back then and built a workaround). But that is now gone.
Other apps have Wx overlays, many map options like AVR, topo updates, visual satellite, trails - all interchangeable and for about the same price with constant updates to their apps. This app is just junk.
Don't bulk up your device with apps that won't work at home, much less out in the field when you need them and when your life may depend on them. Stay clear of this app. It is just like the rest of those wasted dollars on lousy apps you've spent. Don't make my mistake.
can't download quads since going to iphone 5S
with my old phone had quite a few quads stored, but on the new phone they did not get transferred, so decided to redownload -- but even after leaving it running all night it would not finish downloading 1 quad -- it seems to be in perpetual "downloading X Quads" mode -- with the status circle continuously running and it burning thru the battery (had to leave it hooked up to the charger) -- worthless without downloaded quads and frankly -- using the a seperate GPS device makes more sense then this wannabe GPS utilizing your phone
With Family Sharing set up, up to six family members can use this app.
