Can an App Make You a Better Runner?

Excerpt from this article:

Running is simple. But I, with the help of some demanding technology, have managed to complicate it. The last three months have been fueled by a small arsenal of apps, equipment, and playlists that have turned me into a pavement beater with a desperate compulsion to best myself. Their promise was that I would become a better, more efficient runner; I would have hard data that went far beyond the capabilities of a lowly stopwatch and a gut feeling of improvement. But somewhere along the line, technology went from complementary to supplementary in my training. The apps turned a solo leisure activity into an obsessive, not-always-healthy pursuit. Throughout my training, I couldn’t tell if I enjoyed the intensity or whether I’d allowed another set of technology tools to take over my life. But I do know it worked.
