Thanks for the heads up! That bit should be now fixed (looks ok on my iPhone 4), but unfortunately I don't have a retina iPad to test it out. I do know I have to do a little work to fix up the site for mobile.

Blueprint is not a web app wrapper, it actually runs proprietary native code and apps you create are entirely native – unless you choose to incorporate a web view component into your app.

However, if you'd like (since you are probably a programmer) you could use a WYSIWYG view (which is really a UIWebView and for which I've exposed some advanced fields for Javascript, CSS, page begin/end etc) and input your web app code so that you can wrap it in a native app (sort of like people do with PhoneGap, just without having to put together an Xcode project and handle builds and so forth).

Thanks!

Oops, looks like it wasn't actually fixed. Sorry about that – fixed now!
