hey, i don't know if your particular market knows all about this and i don't but you mention "kalmin filter" for improved accuracy. I doubt many users know this term, certainly not your average hiker. I think including an explanation would make the site more accessible for users

The Kalman filter code is in C and available via Github in case you're curious to take a look -

the app looks great. as a hiker the topo maps excited me more than anything else. paper maps are expensive!

only other thing is i wonder why you don't use mapkit for regular maps instead of another map source. with mapkit you get the same great user experience user's expect and all the mapkit improvements coming for free.

I did include a description, but buried it. I was hoping people would be intrigued and Google it. Here's is the description (from http://www.gaiagps.com/acknowledgments ) Kevin Lacker's Kalman Filter - Underneath the hood, Gaia GPS uses a "Kalman Filter" to get more accuracy from the iPhone GPS.

"engineer". Otherwise, very nicely put together, I feel.

We used route-me, since with mapkit we wouldn't have been able to draw tracks or download tiles for offline use.

Hi Andrew, I like it. My 2 cents: 1) Once i read your statement below I understand the app. I think you should make it plainly obvious that the app is for hiking (if that is your target market) 2) (This is based off the assumption that the target is hikers) The people who will use this are outdoors people. The app gui should be geared towards the market. I feel the app & web layout is geared for the high tech crew. L…

Hey CGH,

Thanks for your comments. I've thought about each of these issues:

1 & 2) We want to market the app to anyone who wants to take a track. It being for hikers is a nice bonus, but in our experience, the market isn't big enough. We have a fairly successful app called TrailBehind just for hikers, but we hope people use this for cars, road-biking, etc.

Note that we did have art for this app that was for hikers - just like www.trailbehind.com - but we changed it for a broader appeal.

3. We are better than Motion X for the following reasons:

- we have MyTopo maps

- we have far more complete waypoint search

- I would argue our GUI is simpler

- on things like track accuracy and batter consumption, we are equal if not better

Thanks for getting back on my questions. Hope to see your app in the top 20.

This is fantastic work guys, thanks for doing this. It's especially useful since Topozone.com became expensive. Anyone who's had to head to EMS to pick up paper trail maps or spend hundreds on the National Geographic map packs (me) should be equally ecstatic. Distant, distant future feature request: a little augmented reality - let me mount it on my dash and display a 3D view of what I'm looking at.

Thanks for the compliment, and let me just say... we bought the Nati-Geo map software for over $100, and MyTopo's maps have more details, more trails, and more landmarks. Just hands down better.

And were working on a game overlay for this now called Gaia Quest :)

Stay tuned!

Just purchased. Already like it better than MotionX. Is there a way to search for nearby trails (other than the trails on the scanned topo maps)? not just waypoints? edit: just noticed the other posts about TrailBehind app. Awesome. Now I am all set.

Sorry Joel, no way to search for Trails yet. However, we are thinking about further integrating the EveryTrail API so you could search their trail DB, insead of just doing uploads.

Better than Motion-X huh? You make me feel all warm and fuzzy. Feel free to say something to that effect in your review :)
