Just downloaded it onto a Samsung Galaxy 2. 
1. when the phone goes to sleep, as soon as it wakes up, the position of the map reverts back to the current position. If I'm using the phone to review where I'm going to walk before I get to the start point, this is really annoying. Suggest that:
a. This is the default behavior when the app is recording a trace.
b. Maybe it could be user definable when not recording?

2. No search by town name. If reviewing the map prior to walking,  I have to drag the map across a distance. On the phone, again, really annoying. In addition, at a zoom level high enough to make scrolling easier, the text of the town names is to small to read. I'm pretty sure at least one competitor product allows a settable minimum text size

Hi OSM folks,

I posted my GPS tracking and trail map app to the Google Play store today.  I am writing because I am interested in getting some early feedback from the OSM community, especially regarding feature requests or improvements to the map, website, and app. 

It would also be great to hear thoughts about how juicytrails can facilitate trail mapping.  

Here is the Google Play app store link 

If people like it, it would be nice to get some good reviews going...

The trail map features all kinds of dirt trails (hiking, horse, bicycle, motorcycle, ATV, and 4WD) as well as paved footways and cycleways, all based on OSM data. I started this project basically to fulfill my own trail navigation needs. I have done quite a bit of OSM trail mapping myself, but even I was shocked how many trails appeared when we turned the rendering lights on in the USA. Denver, Boston, and California have the most mapped trails. I have mapped quite a bit in Moab, Utah, Fruita, Durango, Crested Butte, and Salida Colorado.

Here is our burgeoning website and map.


A central goal of this project is to turn hardcopy trail maps into trail dollars. We have actually already been doing this part of the project for a couple years. We are working with a growing list of trail associations to get their trails on OSM and juicytrails.com and then subsequently on hardcopy maps which we will sell directly to trail associations for a very, very small production fee of $.50 per map. The trail associations then sell directly to retailers for $1.50 each, and then the retailers sell for $2.99 each, clearing $1.00 minimum per map. The hardcopy maps have download codes used for installing offline versions of the maps into the Free Juicytrails App. These maps have been a minor hit, and have sold extremely well in some locations.

Thanks for reading.
