Just wanted to give two thumbs up to Jason for making the most excellent pool calculator available in the app store for iPhone. I downloaded it yesterday and am enjoying how well it works, and also how it is a quick reference guide to the basics of BBB and chemical use/application.
It was nice to be working out by the pool yesterday and not have to come inside to get to the desktop pool calculator. I could always load the calculator by going to the TFP website on my iPhone too, but the dedicated app is way more convenient, and dare I say "Mac-Like".
I love it and highly recommend it
