[Cdt-l] Gaia GPS app in place of dedicated GPS unit

FYI - I have been in cooperation with High Sierra Attitude and Guthook guides to develop both Android and IOS versions of dedicated CDT apps. A free demo version of the Android one is here:
The demo has the trail from Crazy Cook to Lordsburg and Columbus alternate routes so people can use them free for the first part of the trail and see how they like them.
IPad/Iphone version should be available in a week or so. The Bear Creek waypoints are built into the apps. The apps are being built a state at a time heading north, hopefully at a faster rate than hikers are moving, so you should be able to do the entire trail using them this year.

This app is considerably more intuitive to use than the eTrex series, has essentially no storage limits beyond those of the device itself so you can load all the Bearcreek waypoints without having to convert them to POI's, and you can view and query all of the waypoints without jumping through hoops. Because you're only planning to get a fix on a waypoint here or there for guidance purposes, rather than following a GPS track all day, 3 meter accuracy and a full week of battery life are less crucial.
> Off-contract Samsung Galaxy phones running Android can be had for less than half the price of an eTrex 30. I've only used the iPhone, GPS functionality is independent of a cell signal using Gaia GPS, but would assume the Galaxy mimics the same functionality. Accuracy is fine for casual use, might take a bit longer to handshake on startup without a cell signal / sim card installed.

Gaia GPS can store 1:24000 quad maps for off-line use, possibly not for the entire CDT at once though, given the very large size of that data set. But probably enough maps could be stored strategically to reach the next known WiFi connection in town.
> The eTrex 20 is my go-to unit for field-recording tracks and waypoints, where accuracy and battery life are the most crucial. But were I to thru-hike the CDT with Bearcreek's data, I'd probably just carry my cell phone and save on the extra weight and fiddle factor. Ultimately GPS doesn't normally factor into one's hiking day to the extent that one might imagine it would.
