Well it is GAIA. Just look at the screen shots. I downloaded the app so I could review it and well they are the same thing but this appears to be lacking some of the functionality in the current versions of GAIA. Only main difference is road route routing which didn't work at times, you have to save them to view them, and well I have Google or Apple maps for that so I don't see this as a strong value proposition. GAIA is going to add that feature down the road according to a member of the development team. It may not be until the end of the year though.
Hema IS Gaia. They are licensing everything from them. Gaia has had cloud support for a long time and yes you can make your routes public for sharing. I bought Hema because I review apps. If you have Gaia there is ZERO need to but Hema. If you have neither and think Hema is going to become more innovative down the road than Gaia then buy it. I doubt it. You can always search Hema cloud or Gaia for routes and import them into either app or any other app that supports GPX files.I like Gaia, but I'm curious about Hema...I love that routes can be shared and stored on Cloud.
Pairing your InReach with the Gaia navigation app gives you a lot more map options. Where available the USFS Raster maps are the best and easiest to read. Gaia removed Google Maps for Terms of Service reasons but as an individual you can manually reinstall them via your cloud account. I am writing up a tutorial to do this. But if what Delorme offers works for you stick with it. I like the higher level of detail which Gaia provides.I'm sure there are better options.
hi Luis have you upgraded your navigation
