Check.in is the Ping.fm of Location-Based Services

I got my beta invite for Check.in on Friday and after just a few check-ins, I’m already loving it.

Now, before you let out a heavy sigh and say, “Really? Another location service I have to check into?,” you’ve got to know something about Check.in. It’s a website set up for mobile use that allows users to check into location-based services such as Foursquare, Gowalla, Brightkite and (Seattle-based) Whrrl all at once. It’s catchphrase is “one checkin to rule them all.”
A line at the bottom of the site says it’s a Brightkite product and credits Martin May, Brady Becker and Jordan Harband with the site’s creation after suffering “severe check-in fatigue.” A Tech Crunch post from last month details how it works.

Now, I wouldn’t classify myself as a check-in fatigue sufferer, but I am totally stoked to see this service available. Of course I had signed up for Foursquare, Brightkite, Whrrl and Gowalla, but I had only been using Foursquare. Checking into multiple services seemed to be a waste of time.

As a result, I was missing out on some pretty cool location-based gameplay on Gowalla and some pretty excellent social networking on Whrrl by not using those services regularly. Check.in solves that problem. Now I can check into all four with just one checkin.

So, if you’re into location-based services, you need to go to http://check.in and sign up for a beta invite. I’m not sure how long it will be before a general public roll out of the site, but a quick look at the @checkdotin Twitter feed shows that they are thinking about (and hopefully working on) integrating even more location-based services. I can’t wait to see how it grows and evolves over time.

What other location services would you like to see available on Check.in? — Google? Facebook? Yelp? What else?
