Note: As of September 2016, there is now an iPhone version of this app as well.
This project was originally bundled together as part of my Mini Apps Collection. This is a completely new version of the program. Since I had to recompile with Android Studio anyway, I took advantage of the much better layout tools and totally redesigned it.
With this program, I had to do quite a bit of tedious setup work. I had to create all the conversion tables and get them into Java. That probably took longer than the actual app.
