Now life has got a little bit easier for architects and designers who want to work from their iPad, thanks to the folks at Urban Design. The Archisketch app (which used to be called Archipad) takes scale into account to and scales your sketches to the real world. The app is full of features to help you, making it easy to duplicate elements, rotate layers and changing drawing size to focus on details. If you only need to do a quick project, you can even download Archisketch for free, just subscribing for longer if needs be. See the video below to get a better idea of all the new features, and download the app here.
