iphone as a poor man’s GPS recorder

I don’t have a GPS, but I do have an iPhone. Theoretically, that ought to work reasonably well as a GPS tracker device. I don’t expect perfect results or usability.

The first app I tried didn’t work right: my trail was filled with strange hops all over the place as points were being recorded even when the accuracy wasn’t right.

Thanks to a colleague I now have the Trails app. Just $2.99. Not perfect, but pretty close. The important point for me is that it filters out the points with not enough accuracy. I used it on my cycling trip last Saturday:

(Updated: everytrail doesn’t use <br/> but ye olde <br> breaking my atom feed. Sigh.)
