Check the report.

Developers can check the application stats.

So I often check the darts counter's stat.

It says my app was downloaded over 450 users and used over 150 users.  I'm very pleased about it.

In the other hand, only one user rated on it.  I want more feedback from users.

Anyway, this report brings motivation for me.

I need ideas for next applications.

Add a fail-safe.

The application reported the exception, by failing parseInt().

Then I add the fail-safe scheme to parse the text for handy-cap area.
