Works perfectly on iPhone.
Love this app for being easy to understand and easy to use, plus the maps are very good. I had a problem with OS13 update and the app. Emailed support, and had an answer and fix quickly.
Muy buena herramienta se la recomiendo
Great maps and user interface. What more do you need?
Edit: The developer helped me with this, so I’m raising my rating. Original Rating: “I notice that the maps leave artifacts from the relief when looking at the topo. It’s very annoying.” From the developer message: Hello, we have to keep a limited number of height samples to keep memory occupation acceptable and our library works with a tessellation of images of 256x256 pixels so when the system is zoomed the shading can appear unrealistic. You can switch off the shading using the menu Settings —> Shading We already switch off it automatically at the given some level, we can anticipate the switch off in future releases.
Good introductory tutorials in both the app and website. Maps are large, but are well detailed; and the download speed is good. Also, maps management is well designed. Possible improvements: Route planning can be improved to take existing trails/tracks into account. Distance calculation is a straight line one; would me more useful if it can follow a path or can have multiple segments.
This is a nice program as long as you download the maps you need before you are offline. I would give it 5 stars except for the intermittent problem that I am having with it marking my track. Yesterday I thrashed through brush for three hours uphill to mark a fence line, when I got to the top the track hadn't registered even tho the little icon was still flashing as active. Grrrrr!
My go to app for hiking
I own a fancy Garmin GPS and hike a lot in Colorado. I decided to investigate iPhone-based GPS systems and after some investigation bought two: Terra Map (free and I subsequently upgraded to Pro for $5) and Gaia ($20). So far, I prefer Terra Map for two main reasons. First, their maps are really good. They have combined "layers" for you in a thoughtful manner. The maps are clear and show trails in my area. No single layer in Gaia achieves this and mixing layers is a hassle (and for full offline mixing in Gaia, I think you need the pro version which has a monthly fee). Second, downloading maps for offline usage is a snap in Terra Map. In Gaia, each download is a custom job. Yes, the Terra Map downloads take up about 50MB each, but that is not a big deal with a modern phone. The Terra Map downloads cover pre-defined areas and the areas are large. The downloads contain the beautiful maps fully available for offline usage. With the Pro version, you can download an unlimited number of areas. The interfaces in Terra Maps and Gaia are both good. I suspect Gaia has a few more features, but the clarity of the maps in Terra Maps wins the day. And you can't beat the price. Also, who needs a dedicated GPS device when the iPhone-based devices are so good.
