Just tried out a cycling app called "Cyclemeter" which cost me $4.99 in the app store but it was such a great investment IMO! Took it out on my ride with me and it logged my elevation climb, distance, time, avg mph, route, date, time and route name. Not sure if the MPH was completely accurate because I didn't have an actual computer setup but the app is really a great thing! All i need is a mount for my iphone so i can hook it up onto my handlebars. Was wondering if anyone else has used this, or any other app for that case, and what your opinion is about it.
