Mark Remy In case you haven’t heard, apps are white hot. (No, not this kind of app. This kind.) Apple has sold approximately 900 jillion iPhone apps to date, and roughly 3 jillion new apps are being added every single day. Just in the time it takes you to read the phrase “iPhone apps,” according to our estimates, 320 million new apps were created. Feeling overwhelmed yet? So are we. In fact, we here at Runner’s World are feeling so overwhelmed that we don’t even have any apps for sale yet. We’re working on that. But I’m starting to wonder if we aren’t overthinking this iPhone app thing. All along, we’ve been working on the assumption that our apps should be, you know, useful. For instance: an app that creates a marathon training plan for you, then imports it into your calendar, then reminds you when it’s time to run and, oh yeah, that you also might be due for a new pair of shoes, and, hey, click here for a list of specialty running retailers in or near your zip code, and yadda yadda. What a bunch of chumps we are. Apparently, according to articles like this one in The New York Times, the hottest iPhone apps are the simple, goofy ones. Like iSteam. iSteam — and we’re not making this up — is an app that makes your iPhone’s screen appear to fog over. Wipe a finger across it, and you “clear” a path, complete with squeaky sound effects. Three guys created this app in seven days. According to The Times, “they made more than $100,000 in three months.” Which got me thinking that there has gotta be a Runner’s World equivalent. Say hello to iBart. iBart is a new iPhone app that, for the low, low price of $1.99, puts RW’s own Bart Yasso on your iPhone. What does Bart do on your iPhone? Hey, you’re lookin’ at it. I mean, come on… It’s Bart! On your iPhone! For less than two bucks! While you fish your credit card out of your wallet, I’ll get back to work on our next iPhone app. I can’t give out details just yet, but let’s just say it’s called “iAmby.”
