Are iPhone GPS lap timers any good?
I am looking for GPS lap timer and data logger options. Is anybody using anything like that here? Recommendations on what to pick and what to avoid?
Based on a quick web search, the two most popular options are Harry's Lap Timer as a cheap solution for those who already have an iPhone or a ~$1000 TraqMate / or VBox data loggers. Now I am sure those who have spent the big money on the laters will be the first to tell me that that's the only way to go, but really? Or do iPhone lap timer apps work good? Please advise. Thanks!
