This app doesn't do much, but what it does do, it does well! Admittedly, this drill chart targets somewhat of narrow audience, but if you belong to that audience, then this app is very useful. To my surprise, I make use of this data more than I thought. Until now I have had to halt what I am doing and go to my bookshelf for the chart. Of course, sometimes it isn't there because I left it out somewhere. But now it is on my phone, and I am happy! My thanks go to the developer for recognizing the need.
