It’s been almost three weeks since we introduced BlockChalk and since then we’ve seen new chalk showing up all over the world. From Helsinki to Hawaii, Calgary to Canberra, the growth has far surpassed our expectations.  BlockChalk is now being used on 5 continents, 42 countries, over 120 cities and more than 250 neighborhoods.

We’ve heard a lot of positive feedback, but a common request has been to provide support for other phones than just the iPhone.  Happily, we can now announce that we’ve extended our browser support to include Google Android-based phones (specifically those running the latest v1.5 of Android).  Thanks to the HTML5 support provided by the iPhone and Android, you’re able to use BlockChalk right inside your phone’s browser, with nothing to download or install.  Simply go to the site and start chalking.

But it doesn’t stop there.  You can now also use BlockChalk on the Palm Pre, thanks to a new application released this weekend by developer extraordinaire Les Orchard.  It’s free and works great!  Les’ app is one of the first to use our new API.  You can expect more native apps to follow, for a variety of platforms.

Thanks again to all of you who have checked out BlockChalk so far.  Keep chalking, and keep letting us know what you think.
