It also really simple to do, here's how:
- First you'll need Fluid (Mac only at this stage). Fluid lets you create a Site Specific Browser (SSB) out of any website or web application, effectively turning your favorite web apps into desktop apps. Download it and make an app for http://bimstop.com
- Launch your new BIMstop app & change the user agent to "Mobile Safari - iPhone"
- Then also select "Convert to MenuExtra"
