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 is the water 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.

I highly recommend this app to help with pool care for the following reasons.1. Simple, easy, and intuitive to use.2. Unlike other pool care apps they are not trying to sell you any chemicals. They are just trying to help you properly maintain your pool.3. They do not track or sell any of your data. That alone is worth the price for this app.4. If you still have questions they readily respond to all inquiries. Like a lot of things, pool care has evolved over the years. These folks have a great book that explains everything from the most basic components to the more subtle aspects of maintaining a pool.We have a new pool with UV/ozone device that in theory will require us to use fewer chemicals. This app allows us to adjust the settings to accommodate for that device and they were very helpful explaining the settings that I need to use, which are not standard.In a world of big business, and data collection, it feels good to support a small family owned business. Yes, there are other pool care apps out there, and many are free. But if choose to support this business I don’t think you will regret it. You will get a personalized response to any and all questions and they just genuinely seem like nice folks. Give them a chance.
Help When Needed!

I really like having someone available to clarify any questions I may have pertaining to my pool needs. Last year when we used the app, we found it extremely helpful in keeping our pool chemicals balanced, and not having to rely on what a pool company told us. We love your advice on how to cut cost of using alternative chemicals as opposed to having to buy what the pool store offers such as using baking soda, instead of alkalinity plus.I appreciate the easy accessibility of the videos that you have linked under how we can help. This is the first year in 18 years that we have scrubbed the sides of our pool prior to adding our chemicals. It has not even been 24 hours and our pool looks amazing!Millie Steed

Best App out there!

This app is so easy to use. My water is so clear and blue because of this app that my friends believe I just dye my water blue 😆. Their chat as well as the customer service is top notch! They will answer every question and take into consideration any app suggestions you make. Ask me how I know? They’re actually creating one of my suggestions as we speak and I have asked many questions and have received replies and they follow up also. I would suggest this app for all pool owners. Matt is very knowledgeable and I read his book from cover to cover. Do yourself a favor and download this app and subscribe. His videos are also top notch and easy to follow and understand!
I finally know what the pool needs now

I understand pool care now!! This app makes everything SO easy. The fact that I can type in test results and it tells me EXACTLY what to add to the water is incredible. I was getting tired of guessing. Or messing up. Also I feel like it’s worth buying an app instead of using the free options out there because the other apps constantly sell you things. Looks like Swim University made a lot of updates to fix bugs in the last year, so I have no problems. The app keeps getting better and better. And if you reach out with a question, Matt or someone will ACTUALLY RESPOND. That’s really comforting customer service.

I'm so glad to hear this! Thank you so much for leaving a review. This is Matt, and we worked really hard on making this app extremely user-friendly, and it turns out that it was worth all the extra effort. If there is anything else we can do to make this better, please let us know. We'll chat with you inside the app.
* Our in-app support chat is improved, and now automatically resumes previous support conversations
* Better chemical formulas (specifically, changes the shock calculation to raise the combined-chlorine target threshold to 0.5 ppm)
* Adds notifications tab and updates tab
Thanks for all the feedback, more updates to come soon!
