Good pocket tool for the gas blender

The Gas Manager is a good pocket tool. I only miss the van der Waal equation. But with a little bit experience, the fudge-factor works good as well. The EAD function does not support Trimix!

Not very good.

This app isn't very good. Feel like I wasted $2.99. Needs an overhaul. Confusing to use, only gives best mix for trimix, NOT nitrox. Wish I could have my money back.
