Let's build: Open source Android exam checker

Let's build: Open source Android exam checker 
(for the poor schools in India and Latin america)

What is it:

I want to build a tool similar to quickkey, but free and open source, 
so that poor schools in india and latin america can easily grade paper 
exams, bringing this technology to the poor schools will enable them to 
do more and better exams, and will make the teachers have more time to 
either be with their families or dedicate more resources to class content 
and creativity.

Why i'm doing it: 
I want to build it so schools have access to better technology, in order 
to help bridge the gap between the poor and the rich in Colombia (my home 
country) and other poor countries around latin america and Asia.
