At school right now we are looking at various options for whiteboard apps on iP2.
To begin with we used apps that were really art apps, like the fantastic 'Brushes'. It's a great app but it was never really created to be stuck as a classroom whiteboard tool. Kind of like making Michaelangelo paint the bathroom!
Then we used the equally fantastic Penultimate. A definite step in the right direction. Easy to use and does exactly what it says on the tin. Some limitations as a whiteboard also; although its great for handwritten text, it doesn't allow you to add printed text or graphics and consequently looks quite 'infant' on the big screen, my handwriting doesn't need any help to look infant!
So, today I gave a test run to whiteboard HD, a dedicated whiteboard app with a four star rating on the app store. You can choose your type, write by hand or add text in a very simple way. The app also allows you to add images and shapes, again, very simply and I was really impressed with the look of the whiteboard on screen.
My one gripe was pointed out by Fraser Speirs, my buddy and school IT guru; the app only allows one whiteboard per project wheras Penutlimate allows multiple pages per project which can then be mailed to students, printed etc.
So, no perfect solution, but I think I'm sticking with whiteboard HD until something better turns up!
