## What is Pooldash?

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

This app was built for professionals, but don't worry -- beginners can use it too! Just enter whatever chemical readings you prefer using any test kit you own, and pooldash will tell you exactly what chemicals to put into your pool.

We, the creators of pooldash, don't know everything there is about water chemistry. That's why we created the "formula" system, so that people around the world can share their own custom calculators within pooldash.

By default, 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 target 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 chlorine, salt-water, bromine, copper, and all sorts of swimming pools.

You can save your history and email it, export it, or even ignore it if you want.

### 5/5 — The best pool chemistry app out there flat out.

*2025-05-30*

I love using pool Dash to manage my pool chemistry and keep track of the chemicals I’ve added to my pool. It does leave a few things to be desired, but it absolutely smashes all of the competition, very easy to use and relatively beginner friendly.

### 1/5 — Copper Pool

*2023-07-06*

Says it will work with copper. Used it and says I need 600# of salt!!!!  Wasted $20 on it.

### 5/5 — Great app. Improvements still coming.

*2022-12-08*

This is a really great app for people who do pool balancing.

We recently installed a pool at our house and I took on the care of the pool myself rather than paying a company to do so. After calculating my volume I was up an running.

This takes the guess work out of how much of each chemical to add once you’ve taken an accurate reading.

### 5/5 — Great Software

*2022-06-06*

This app is free and has an “open source” licence meaning the source code is freely available for download. It’s not linked to specific brands. Interface is smooth and looks great.

### 3/5 — Don’t know the word used

*2022-04-17*

I preferred the older app, more simple. Just telling you ph+ and ph- to add…
Now chemical words I don’t understand (muriatic acid, carbonate sodium…)… 
If someone know the answers

### 5/5 — Best app for hot tub care

*2020-09-28*

Perfect for using a basic 7-level test strip. Can enter how many gallons and the app tells you how many ounces of each chemical to add.
