Cool idea, but it needs a LOT of work. On an iphone the icons are so small you need a point stick to move and wire, and they show up in the extreme corner of the screen where its often not easy to get to with a phone case. Everything there is tiny and hard to see. Not a typical Apple general release. Is this an inhouse app for a school maybe? And its painfully slow.
Ill try on the iPad and see if its hopefully any better there.
