Missing features I have used this and Locus for backpacking. The maps available in this app are great because I love the Trials Illustrated / National Geographic maps. However, the app lacks basic features found in Locus. Since I never go into the woods without a paper map for backup - I may as well buy the hardcopy map for the info I would get from using this app and use Locus for navigation.
The real deal!! Backcountry tested This app could be an extremely convienient tool. I tested this on my last 53k canoe trip into algonquin interior . I found it to be very accurate, reliable gps, I never dropped signal, multitude of great features built into the app as well. Excellent tool for the toolbox if your tripping.
Great tool. I now use this instead of my gps (which broke down recently). Tested in several back country locations in UT. Accurate, put phone in airplane mode and still works not burning battery. Multiple maps available to download.
Pretty great! I love the referenced maps, and the fact that you can find yourself on the map and place markers. My one and only problem is that this app will download and open ALL pdf documents, no matter what the source, even though I have cleared the defaults from my phone. I have it set so that a different app should be opening open all my pdf docs, but this hijacks them and opens them anyway, which is not helpful as I use many pdf docs that are NOT maps. Developers, help?
PDF Maps works well with sites like CalTopo for generating custom PDFs and working with them offline, or for downloading other maps from within the app. The app has three major missing features: no ability to turn layers on and off, no support for multi-page GeoPDFs, and no SD card storage for the app or maps. (They say this is to "protect vendor content", so why not encrypt the maps instead??)
Record tracks and lost the work It is very unfortunate to record one day on the mountains tracks for work and afterwards to not be able to export to a gpx or kmz file. Otherwise is a pretty good app, but unuseful for recording tracks to be used outside the app. :(
New in PDF Maps 1.7.3 Android:
• Fixed an issue where the SD card was not accessible on Android 6.0
• General fixes and improvements
