Re: iphone app to measure walking distance
Cool! I remember when husband and I used to hike a fair bit, there were quite a few times where we'd cry "where the heck are we?". Well we used a different word from heck. GPS must make it all easy! Except the actual walking part. :)
Nokia phones do something similar and they can interface to some Polar HRMs too.
Bikely, which is a site for creating bike maps will upload some sort of GPS format and map it out on a google map.
