Thousands of professionals across the world already use Pool Doctor to keep their pools blue... you should too!

This app is not for total beginners -- It is a powerful digital tool for professionals or enthusiasts.

But don't worry! Instructions are constantly scrolling across the screen. Just enter whatever chemical readings you prefer using any test kit you own, and Pool Doctor will tell you exactly what chemicals to put into your pool and why.

With Pool Doctor, you can adjust the chlorine, bromine, salt, pH, total alkalinity, calcium hardness, and even the cyanuric acid levels in all of your pools. You can even configure the ideal ranges and chemicals used to treat the pools (see screenshots).

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 now saves basic reading and treatment records for all of your pools!

Pool Doctor only shows you readings that apply to your pool type, so there is no unnecessary confusion!

Pool Doctor will now calculate the Langelier Index automatically if you take all of the required readings!

Pool Doctor now includes a shock calculator! Just enter the free and total chlorine levels, and Pool Doctor will automatically calculate how much of your preferred shock chemical is necessary to bring your pool to breakpoint chlorination.

Improve App

Should be able to customize the order of the readings input page from top to bottom. If i want pH first then i should be able to move it there. Be nice to mirroe the test strip or test equip in the same order

Great app!

This app is a great help in managing your pool! It’s well conceived and laid out, and very easy to use. Some bonuses: click to cycle through different units of measure when adding chemicals, specify the chemical you want to use for each type of adjustment from a drop down, customize your own target levels, and edit the recommended chemical additions if you decide adjust or defer to later. The developer evens welcomes feature requests. Highly recommended!

Thank you Pool Doctor!

This app is the best. I’m a neophyte pool maintainer (we let our pool guy go last week) and this VERY handy guide is easy for even a newbie like me to use. Just input your readings, press a button and voila! Pool Doc tells you just what you need to do to get your pool in balance. And best of all, Pool Doc doesn’t require you to input your email to create an account, so no annoying emails selling you stuff you neither need nor want. Again, well done Pool Doc!
