This is a very fine app for our N900. Thank you.
I think i see 0/18 (or something like that in training mode). I answer 0 but it was a bad answer ?
I found the big flash green "good" not very usefull in training or race mode (it disturbs me). But the big red "false" is fine.
The order of the numbers to clic on the screen is not intuitive.
In the series mode (very fine), the proposed calculations are a bit too linear.
Thank you again ...
