I use e-liquid recipes .com and then create notes in Evernote to further organize for offline use. Working well for me.
My wife is a software engineer, so once things calm down a bit with the baby I'm going to ask her to write an app for not only recipes, but inventory managing with alerts and vendor links
Thanks Dready. The one I'm using right now is one Peng suggested, I have e-liquid Calculator.com but haven't used it, I almost panicked about the Evernote recipes I have but then realized it is online and simply logging into the site will transfer that. Now I have to figure out if I have/want to use Safari or another browser, and what other browsers are compatible with Mac. OMG so much to learn, my poor old head is spinning, excellent timing on my part to do this while in the middle of an art class learning a completely new app.
In any case my brain is getting a lot of good exercise and I'm fairly certain that I don't have Alzheimer's yet because the new stuff I'm learning is sticking.
I need to make myself concentrate long enough to make a flavoring order sometime soon as well, I am pretty sure I will be running low on a few that I use all the time. Thank you again Peng and everyone else that encouraged/pushed me into DIY, I simply cannot imagine paying retail for juice anymore, add to the fact that retail juice doesn't taste good anymore, it's just way too sweet.
