時間あたりの英単語の回答数や各英単語の回答にかかった時間がわかれば良いなと思いました。
I have used mikan which is an application for learn by heart English word.
I use the app for almost thirty minute per day.
Now I'm in top 10 of ranking by prefecture.
This app user can know answer number and answer time on that day.
I think this is good.
Although, I come to want to know another two types indicator.
First of all, it's answer number per time.
Time of standard is anything well whatever one minute or ten minute or another.
Another one is answer time each word.
Probably user can see how fast do they answer with these, isn't it.
As a result, user will be able to understand which word really is not good at.
Reflex answer is much better than just answer, isn't it.
If the app processed these data it could be much better app.
However, the app may has already these indicators, I don't pay for the app, so I don't know.
