Does anyone use these apps and get accurate distance results? It makes sense that the apps' accuracy can only be as good as the GPS signal, but for me they haven't even been close when my signal strength is very strong. After a 3 or 4 mile jog, I could use the results to decipher what my path was, but the distances are way off. A 3 mile run (calculated using gmap-pedometer.com) showed up as almost 4 miles. The reason is because the app tracks my route as zig-zagging back and forth across the street rather than showing the straight line I actually took. I live in New York City and I wouldn't expect it to work well in areas with lots of tall buildings, but the accuracy doesn't appear to improve at all when I'm all the way out on the West Side Highway with no tall buildings nearby. Anyone have any better luck? Are there settings that I should change? I am using the stock settings, which appear to be leaning towards the more accurate / higher battery drain end of the spectrum. Both of these apps have so much potential and could be very useful tools, but being off by more than .01 or .02 miles per mile would render them useless to me.
