@monz We certainly would like to try and work with children at an earlier age.  However, its challenging because all of the apps available assume some sort of native or knowledgeable speaker guidance.  Let me give you an example.  During some site visits we discovered that because we weren't dealing with rotation completely correctly in one of our apps that the children would sometimes use our app upside down.  So they were seeing all the letter upside down.  Not good!  Because nobody in the village knows any better there was no one who could recognize that this was a problem.  Apps that are designed to instruct in the total absence of someone who already knows the language are difficult and require quite a bit more development work than your average educational app.  But certainly the earlier we can  begin this sort of instruction the better.
