Doceri is an interactive whiteboard for the iPad. The tool can also be used for screencasting lessons. You have two choices for creation. When using your iPad alone you are doing what is called screencasting. You are creating something on the screen and then recording your voice over the top of it. This is a great way to go about teaching especially if you are using the flipped classroom model (only works with the iPad version), where lessons are recorded and watched by students at home. By no means though is this transforming our education. Using it this way you are at best substituting.
Where I believe that it starts to move up the SAMR model is when you use it with a computer. I have to be perfectly honest and upfront with you at this point though. The highest level that I believe this tech allows us to reach is augmentation. The reason for this is that while it allows you to be mobile in your classroom while presenting, I see no higher level of transformation taking place.
Essentially it does allow you to move freely around the classroom which is a huge positive. I also think it allows students to present in front of the class without being in front of the class. Howeverm, my students can do that now with their own non-technological whiteboard.
As it should Doceri costs money, but it looks like it is just a one time charge of $30 for a desktop liscense. It comes with a 30 day free trial so that you can try it out prior to buying it.

This tech is similar to Reflector 2, which is an mac based desktop application that allows you to project your iPad screen onto your white board. Doceri is a little bit more fluid in my opinion, and allows for you to use your desktop as your primary base. It also allows you to do more with lesson development as seen above.
