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.

Helpful App, kinda pricey, setup & user interface leaves a little to be desired

This app works and is more helpful now that you can sync across devices with a cloud account. But, you'll need to setup each device - you cannot sync your chemicals and target levels across devices. Input controls and design is rudimentary and not well thought out, but the app functions well enough.

Really useful app, best pool app I've used

My family has been in the swimming pool industry for over 50 years and I honestly use this app every day and find it to be very accurate if used correctly. I could see how someone could make a bad review if used incorrectly.

Fantastic for non chemistry inclined home pool owner

Easy to use and extremely accurate.
This will be my 3rd summer using the Pool Doctor app and it has literally saved me hundreds of $$ per summer by avoiding costly water balance extremes.
Thanks John
