Any Good Android Soap Calculators?

[songwind]

I love having the ability to do lots of work in the palm of my hand, and I'd be happy to have a soap calculator on it.

The ones that I've found online don't seem very well reviewed, though.

Does anyone here have a recommendation for a good one?

I just use the Brambleberry app. It seems to work well for me!
