I don't think there is ONE that is the best, so I use a few. They are cheap enough, think of a price of a couple of beers at a bar. So I use 3 apps plus paper maps as backup (iPad can overheat or crapout). My cab setup has the iPad mounted just above the radio level, easy to access. Here is my take, and yes, I use them on trails and off-road on unmarked forest trails. Bushwacking only on foot though.
GAIA GPS on ipad is the most versatile and easy to use for my use.
- Must download maps of area you will be operating in
- Has many different map views, from current biking, hiking maps to old USGS topos you can choose from
- Easy way to create tracks, waypoints, and add photos of waypoints to help remember "that cool campsite"
- Data for tracks shows time moving, time stopped, elevation changes
- Can call out distance while creating track, I find that very useful when wondering "how far am I from the main trail?"
- Your tracks will be "published" so you can see them on your GAIA account (free one) on your computer
- While creating tracks you can change info on the screen, I use elevation and current speed but you can customize it
- Very easy to upload new gpx tracks or waypoints from other sources
- Very easy to email information to others
- Can also have it on smartphone, and all your information is shared between devices. I prefer the big iPad screen as I am old
ScenicMaps
- You can buy the entire US and download into your iPad or iPhone, or sections at a time. I have both but mostly only use the East version
- Takes a good bit of memory to have it all, but you will always have a map of anywhere you are
- The downside is the maps can be missing a good bit of info, they can be a outdated and not have enough detail
- You can create tracks, easy to save and keep but a little clunkier than Gaia with a lot less options
- I use it strictly as back up, or just in case. I do use it for foot wanderings in the mountains or bushwacking, It does have a lot of foot trails pre-programmed so you can go off-trail and connect to another if that's your thing
- Any info will reside in the device it was captured on, so no PC connection
- Otherwise, rugged and simple with little detail
Avenza Maps
- This is a PDF map reader, not a map by itself like the others. You install the app, then buy or download free maps and "open with" Avenza and thats it
- Some clubs, like the guys working the Daniel Boone trail map, use this app to sell their map, simple to use and GPS will find you on the map
- My use, most of the time, is to view the NATGEO Trails Illustrated maps. I am a fan of those maps for their detail information of trails, topos, waterfalls, etc. I think they are awesome and have purchased a lot of them on the Avenza store
- The NATGEO maps cost the same as paper, but you can zoom in with incredible accuracy which helps a lot when you are blazing a trail.
- You can also create waypoints and tracks with Avenza, but not as reliable as GAIA.
- You can add KMZ files as layers to the NATGEO maps to save new tracks from other sources. Simly just select the KMZ file and "open with" Avenza and done. But you have to have Avenza openned with the map you want the KMZ file to go to. Otherwise nojoy
- You can rename way points and add photos, so you can remember "cool campsite here" stuff
- Unlike GAIA or Scenic, you can go off-map and have to change maps during a run, so its not continuous like any paper map would be.
- The NATGEO maps shows most USF roads and gates, including closed gates and seasonal gates, so if the gate is open you know if it was meant to be open or some yahoo broke the lock
So long response, but hope it helps with decision. There are other free aps out there I have tried, but were too clunky to work or needed too many steps for my liking. I need simple stuff when driving. In the end, to me, this stuff is cheap compared other crap I bought and never used. To me they are cheap, so I got them all.
