I own both Hema NA and Gaia. I bought the Hema app based on the hype created in the overland community by Overland Journal, and Expedition Portal. Some of this "hype" was about the app and hardware available in Australia, and the Apple app. It all sounded so good, and it was on my list of things to get, so when I heard at Overland Exp West that it was available in North America for Android, I bought it immediately.
At this point, I no longer use Hema NA on my android device. Gaia is so much better at this point in time for actual use when using it offline. The two key points for me are:
- offline maps, Hema can only use the device internal storage, while Gaia can use an SD card. Isn't the point of overlanding to get away from people and cellular signal? If you agree, Hema misses the mark, as most devices don't have enough internal storage to download enough map tiles for just 3 days of overlanding.
- The "Gaia Topo" map is far superior to any of the maps available in Hema. The Gaia Topo map scales better as you zoom in and out, making it possible to read the text (road and place names.)
If I could return the Hema app for even a partial refund, I would do so. I don't intend to use it again with it's current feature set.
My feedback applies to using both apps in Arizona, California, Nevada and Utah, on an Android Samsung Galaxy S5.
