4DSoftTech has a free WhiteBoard app which is so easy to use on a mobile phone. I would not even have considered a WhiteBoard app as an option on my phone but this one has good functionality and is easy to use. I actually like the KidsBoard. I think it is wrongly named! I use this aspect of WhiteBoard a lot because there are so many good features if you want to put something together. The WhiteBoard site explains very clearly what it can do and gives some good visual information as well. It is exclusively an Android app at this stage. There are other apps on their site you might like to investigate.
