Does it all

The app does everything you want it to, with some amazing extra features in there as well! Plus the Developer is really vocal and dedicated - a rare thing nowadays!

Mathhammer on the go!

It’s mathhammer, but portable! It even lets you save unit profiles so you can quickly see how easily you’ll kill your most hated xeno monstrosity of choice! 10/10 would exterminatus again.
