After smashing out this app out in a weekend a couple of months back, I've been sitting on it for quite a while now. Thought I'd just upload what I had so far for you peeps to have a look over.
I've basically taken the idea of Graham's liquor calculator, and created something similar as an Android App. I haven't used Graham's code, so it will calculate things slightly differently, but it should give very very close values to his. The water profiles are the same as his, and there's the option for CRS or boiling to reduce the alkalinity.
At the very top of the screen there's a bit for inputting the salifert alkalinity test value, and it calculates the alkalinity from that. It will also save all your numbers for you, so you dont have to keep digging out those ion values each time. And the salt additions are in tsps as well as grams.
Going to be pretty busy over the next week or so, but after that I'll be able to get this properly tweaked up.
Some functionality isn't working yet, but it's mostly there.
Here's the link
