I'm new to this site but want to know if you guys use anything besides poolcalculator.com to help with your chemical dosing.
I have an iPhone, and from what I can tell the most popular apps are:
Pool Chemical Dosing
I like the idea of having an app to do the calculations, but I don't want to waste my money if the apps aren't actually helpful. Do any of you use any of these (or other) apps to balance your chemicals?
