Works well

I havent had any problems with it. There are a few glitches though.
1) It doesnt seem to find my location until I hit START. Then it takes about 30 seconds for the GPS to track. If you hit RESET then restart it, it works just fine. I dont think its location aware until you actually hit START, but this gives you 30 seconds of useless data.
2) Speeds are still erratic (version 1.1). When Im running, its typically 7.5 mph (8 min/mile). This will show me somewhere between 4-10 mph (Im not doing intervals).
3) It needs a stopwatch.
4) There should be a way to fast forward through songs. If you go out to the iPod, this app stops collecting.
Justin provided a very quick and effective update between 1.0 and 1.1. Lets hope he keeps up the great support.
