updated again

I'm sorry for the visitors of this app. In the yesterdays version of this app,

I've found another bug today.

The string of how to read numbers did't show correctly.

So I fixed it immediately and upload it again.

In order to make it run properly, please delete the cash of the browser and 

reload the page of my app again.

Now I'm trying to reduce the size of my app and make it light and small 

in order to make it run on smartphones.

In the early stages of the development of my app, 

my app tend to be premature and contains lots of bugs

and I have to update them often. 

But I'll try to make it better, so please check it sometimes.
