Want to get serious about pool maintenance? With Pool Doctor, you can adjust the chlorine, bromine, salt, pH, total alkalinity, calcium hardness, and even the cyanuric acid levels in your pool. You can even configure the ideal ranges and chemicals used to treat your pool. Pool Doctor gives all results and explanations in pounds, ounces, grams, kilograms, liters, gallons, or even in the number of scoops (you can enter custom scoop sizes); and changing units is as easy as pressing a button! This app supports regular, salt-water, or even bromine pools. Pool Doctor only shows you readings that apply to your pool type, so there is no unnecessary confusion! Unfortunately, Pool Doctor is not available for Android phones or tablets.
