Topo Maps

I'm a land surveyor and this app comes in extremely useful. The quads are pretty well registered and the contours are quite accurate. The biggest downside is that many of the usgs quads are not current.

OCTOBER 2025: The issue with being unable to download new maps to my device has been fixed. when trying to download new maps, I would get an error message saying the map wasn’t available for download or something like that. I sent an email to the app developer last night, and six hours later he had responded and said the problem was fixed. And it really was! After all these years, this is still the best topographic map app out there for use in conjunction with hiking and exploring.

I’m not a fan of the set up. They will NOT refund your money if you don’t like it.

This app is incredible. Blows all others away! …if you’re a naturalist, hiker, or love being in nature, then get this app. GPS functions very well and the US data from survey is incredible and accurate. I’ve used this app while serving USCG & DHS in Alaska and found it works extremely well while having very little to no listed cellular signal… literally in the middle of the deepest of terrain— I had used this due to the nature of my service for a backup in case I ever faced any emergency situat

I absolutely love this app! It is seriously the best on the market. I use it for work everyday and would recommend it to anyone. You don’t need cell service once you have downloaded the maps you need. I live abroad and cannot find an app that matches the perfection that this one does. I hope someday soon there will be expansions for the app to include the UK and Europe! Any chance let me know thanks!!
