37Signals has announced the exciting launch of Basecamp Mobile, an official web app that works universally across Webkit browsers on mobile smartphones. With experience in designing mobile applications, 37Signals’ goal was to release a strong, universal HTML5 app that didn’t require in-house iPhone & Android developers. The end result? Basecamp works across WebOS and Blackberry devices too!

A big part of this initial release was nailing the basics that mattered the most. We had to make a bunch of hard calls about what was important enough to make version 1. That meant leaving some things out and not bringing full functionality to other things. For example, you can view Milestones but you can’t add new ones. But you can view, add, change, and assign to-dos. We plan on rounding out the functionality as time goes on.

Jason Fried notes that this version will launch without every editing feature under the sun, but that doesn’t mean you won’t have the ability to view Writeboards, reply to messages, or browse attached PDFs. At MacStories, we’re very excited that there’s finally an official mobile solution for one of our favorite products, and we can’t wait to see where the company takes us. If you breath the 37Signals mantra, read up on the launch notes via the Signal vs. Noise blog before catching the “Works Without Apps!” seal of approval on the mobile landing page.
