Just recently discovered this site. I’m loving it so far for creating your own tracks, editing tracks you’ve done. For instance, I used it to create a new Three Creeks Trail track that we can use the next time we go there to hike off the trail to avoid the 2-3 miles on the road. They also have an app for Iphones and Android; however, so far the app looks pretty basic compared to the capabilities they have on their website. Check it out and let me know what you think!
