I remember Helen Keller said "what would you look at if you had just three days ? " ,
Yes, it is a good question.
Based on some research, in the world now we have around 40 millions people in the dark. and maybe
10 millions people is suffering " Poor vision ". But maybe only 10 % have learned Braille Skill.
If your friend or parents just become a blind, he(she) is suffering a huge pain, please encourage him to learn Braille to open another window from his mind. And that is the reason why I developed the App.
I wish you can share the love and useful tool to everyone !
