Techgen has created a pretty good review of the Assembly app and the video goes through the key points of using it. I have been using it on my iPad and haven’t, as yet, encountered the problems he had on his phone. I can manage the shape choices across the bottom bar of my iPad Air quite well . What I can’t do is find out how to put in my own backgrounds as he did . There doesn’t seem to be an option for that. Maybe it comes with the subscription to Assembly Pro.
I am running the free version and have plenty to be working with and the shape packages are now all free. You can easily download them as you want them. I run it with the snap to grid functionality because it creates very precise placement and image manipulation. It is easy to change the colours and add text and to bring pictures forward or put hem to the back. It is an app which fits in well with the ACARA Digital Technologies curriculum requirements because students can learn how to manipulate objects, how to apply graphic design ideas , how to collaborate and how digital systems work to create meaning. It’s a great app for creating logos, simple designs and not so simple designs when you get good at it. There are tutorials on You Tube and the Assembly app site itself points you in the right direction. Currently it’s an iOS app. There is a review of it on stuff.tv . It saves the created images in HD and the size is about 4000 pixels square , so a good size for manipulating further and reducing them will not disturb image integrity.
