I was crazy excited about the prospects of Nike+ coming to the iPhone, having used the fitness tracking program with a nano for over a year. But that didn't happen; instead, RunKeeper did, and it's even better. We've covered RunKeeper (along with another Nike+ alternative) once before when we detailed how to roll your own Nike+ iPhone for free, but RunKeeper has since seen some excellent updates worth pointing out. For one, the app works better for me than it once did. It's more accurate when mapping out your run, which was my biggest problem the first time out. It even embeds your route on a Google Map inside the app, something Nike+ so far hasn't come close to. Second, the pro version of the application ($US10 in the App Store) now has audio cues. By default, that means a voice interjects how long you've been running every five minutes. (E.g., "Five minutes completed.") What's more, you can tap the screen at any time during your run and the voice will read off all your stats—including pace, distance, and time—so you don't have to raise your arm and crank your head to try to read out your stats mid-run (though the large display makes doing so rather easy, too). If you're nuts for Twitter, RunKeeper can even tweet your latest workout. RunKeeper comes in two flavors: A free, ad-supported download and a pro, ad-free version. The $US10 price tag isn't bad for the pro version, but if you're not keen on spending the cash, the free version does everything the pro version does minus the awesome new voice cues. If I had one recommendation for the folks at RunKeeper, it's that they need to improve the look of their web site. The data is good, but compared to the sheen of Nike+'s online face, it looks downright 90s. If you've been using RunKeeper since we first covered it (or any other Nike+ like app), share your experience in the comments. It's worth mentioning that RunKeeper is iPhone 3G only, since it requires GPS to work.
