Best iPhone app to show current progress vs. personal best
I'd really like an iPhone GPS app that gives me real (or near-real) time comparison of my current progress in my commute against my personal best. Besides a good benchmark to bike against, it would also give me a better estimation of what time I'd get to work or home. It looks like RunKeeper and Strava will do that in the premium versions, but I'd really like something with a one-time up-front fee, rather than their expensive recurring payments. Does anybody have any good suggestions for something like this?
