About this app

Pool Care by Swim University is the pool chemical calculator that teaches you why, not just what to add. Whether you're staring at a green pool, dealing with cloudy pool water, or just trying to figure out how much chlorine to add, the app is here to help.

Enter your water test results and get a custom treatment plan in seconds. You'll know exactly what chemicals to add, how much, and in what order. It's like having a pool expert in your pocket, backed by Swim University and trusted by over 400,000 pool owners.

POOL CHEMICAL CALCULATOR
The built-in pool chemical calculator handles chlorine, pH, total alkalinity, calcium hardness, cyanuric acid, and salt. Every recommendation is based on your pool's volume, type, and current water test readings. No more guessing with dosage charts or doing math on the back of a chlorine bucket.

WATER TESTING MADE SIMPLE
Enter your pool water test results, and the app instantly builds a step-by-step treatment plan customized to your pool. It puts your chemicals in the right order so nothing cancels out, and tells you exactly how long to wait between additions. Pool water chemistry has never been this easy to understand.

FIX COMMON POOL PROBLEMS
Wondering why your pool turned green overnight? Or why the water is cloudy even after shocking? The app helps you diagnose and fix the most common pool problems, from pool algae and green pool water to foam on the surface, burning eyes, and water that smells like chlorine. That chlorine smell actually means you need more, not less. The app explains all of it.

WORKS WITH EVERY POOL TYPE
Whether you have an inground pool, an above ground pool in your backyard, a saltwater pool with a chlorine generator, or a hot tub on your patio, the pool chemical calculator adjusts to your setup. Enter your pool details once, and every recommendation is tailored to your water.

LEARN AS YOU GO
Most pool apps just spit out numbers. Pool Care by Swim University actually teaches you the basics of pool water chemistry as you use it. You'll learn why your pH matters, what causes algae, and how to shock a pool the right way. Over time, you won't just maintain your pool. You'll actually understand it.

Ratings and reviews

I installed the app, opened it and made my way to the 3rd "tour" page, then it stopped. I couldn't get beyond that page. I uninstalled and reinstalled the app a few times, nothing, it's still not allowing me to move past the introduction or "tour". So, I'm uninstalling it again and moving on. It's not worth the frustration.

This is the app I've been wishing for for decades. Makes pool care simple, and is clearly based on a serious dataset of pool care knowledge, which I'd expect from SwimU, having been around forever. Intuitive, easy, smooth.

like many of the other reviews the app takes me thru most of the tutorial and at the end, it says your on a streak, the only option is continue tour but nothing happens. Closed and opened app multiple times, same problem. I am using an android phone. Are you aware when a fix will be released?
