Educating through apps

Recently after a long inner dilemma,to choose between apple and android, I finally bought myself a Samsung Galaxy Note. Every moment it seems to delight me with all that it can do. Right now blogging from it but without typing. I am simply writing with my s-pen on the screen.
It is so much fun. My entry into the world of smartphones and the App market has just started. Every now and then I am experimenting all the things that I can do with this small magic tool.
As of now writing questions in your own handwriting and mailing it to students just happens in a few seconds. Options available are s-memo, Skitch and even drawing using Polaris office word doc.
The few apps with which I started off immediately are...

1. Annotating student's work happens in no time with iannotate Lite. You can check and annotate any pdf as you would do normally, a hard copy,  with the S-pen and mail it immediately.
2. Another interesting app that I used to teach and clear doubts to my IBDP student was "whatsapp". Though this app is for free Sms to people all over the woold, the way me and my student used it was amazing.

My student had a doubt in one of the questions of a past paper. He took a screenshot and sent me at whatsapp. I solved the question on S-Memo, attached a 30 sec video explanation and sent it. Then he attached an audio file asking his douibt. The ONLINE free chat session with all these facilities really made it so very, easy.
Wait for the posts about other apps that I am going to use from my Samsung Galaxy Note.
