## What is Pool Care by Swim University?

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.

TRUSTED BY 400,000+ POOL OWNERS
Swim University has been helping pool owners take care of their pools since 2006. Our YouTube channel, blog, and video courses have taught hundreds of thousands of people how to balance pool water, clear up cloudy pool water, and keep their chemistry dialed in all season long. This app puts all of that knowledge in your pocket.

Pool Care by Swim University requires a subscription to access all features. Start with a 7-day free trial, then continue with an annual subscription. Your pool water chemistry doesn't have to be complicated.

### 4/5 — swim u

*2026-08-25*

ok the courses along with the books are helpful. i actually dont even own a hot tub but if there is a future for one ill have the info. the app is also a great resource as they do listen and respond. i like the videos for extra credit if you will. and its updated with even more info. i think the part you can plug in your pool chemistry is pretty darn cool. i never seen one until now like this one thats really cheap in my opinion for what you get. i bought a crystal water monitor bout 3 yrs ago because i too like many others was frustrated with misinformation. so i got the monitor. i didnt know swim u existed at the time. the app with it is good but doesnt have videos just knowledge base articles and info. so i use the swim u app for tracking my other pool stuff like psi my cleaning etc. between my other device and this ive got so much good info to pull from. also i mentioned some things in the chat about the course etc and if there was something say kinda different than a video posted matt actually clarified it. ive eliminated pool store visits and just order online the few chemicals i need onhand. im learning alot and not being crazy about chasing up and down readings as its getting easier to look and say like oh i lowered this and this went up knowing now it will balance out. i dont pay for say another subscription ontop of one i already have unless its valuable. this is i think. takes all the chemistry and intimidation out of the equation. thanks so much i love learning!

### 4/5 — Fantastic App!!

*2026-08-10*

I love this app, the YouTube channels and I’ve learned tons about pool care. My only issue is that I couldn’t add another body of water and I needed it for pool and spa. Great customer service! Would highly recommend.

**Developer response:** Thank you for taking the time to leave this feedback. And glad you like the YouTube videos. As for adding more options like an additional pool or hot tubs, that feature has been requested a lot, and it's coming soon. It's on our short list. -Matt

### 5/5 — Excellent App

*2026-08-06*

Easy to use and understand. Takes the guesswork out and tells you exactly what to do.

**Developer response:** Love hearing this! Thank you so much for taking the time to leave a review. -Matt

### 1/5 — Overpriced

*2026-07-07*

Don’t waste your money. 7 day trial and then $50 a year is overpriced.  Pool Math app does the same thing for $7.99 a year. SU videos are great, but they are free on YouTube. If they were more reasonably priced I would use it but where it stands now it’s just a rip off.

**Developer response:** I appreciate the feedback here. I think PoolMath is a good alternative. However, they force you to follow their strict rules for what TroubleFreePool thinks about pool care. It's not very flexible. For example, the only sanitizer settings you can pick are liquid chlorine and salt water. There are many other options and should be made available to all pool owners. 

I think I have a lot to learn from this feedback to improve our app to make it worth well over $50/year. Currently our app provides all the same features as Pool Math, plus live chat support, and exclusive library of video/article content (and growing), flexible and customizable pool care treatments and plans. All with the goal of helping pool owners stay on track and save money.

As you pointed out, our teams creates FREE videos on YouTube and all social media platforms every week. Plus, we write and update all the free guides on our website. This is all possible because of the products we sell and maintain. As the owner of Swim University, I'm singularly focused on providing the best products and content about taking care of a pool. That's my only job and I'm very proud of that. I hope one day you consider trying our app as it continues to get better every week. And if you every have a question, feel free to reach out via email or the app and I'll be there to help you personally.

Thank you for the feedback. I will do my best to make sure we continue pumping out free videos and articles.

### 5/5 — Best App out there!

*2026-06-05*

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!

### 5/5 — Great App - Highly recommend

*2026-05-28*

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.

### 5/5 — Peace of mind

*2026-05-26*

So far I’m still on my seven day trial and I must say, balancing the water and understanding pool chemistry using this app is fantastic. All the instructions whether they are written or in the videos are all easy to understand and the steps are easy to follow with confidence. Love,love, love this app!

### 5/5 — So good!

*2026-05-26*

I thought the app would just help me after I typed in my numbers … but they responded when I needed help! I love the app and I have the book and I love his channel and our pool, if I may say , is clear for first time in long time! (We got rid of bad pool guy) .  But these people are awesome and couldn’t be happier

### 5/5 — So easy to use

*2026-05-06*

I love how easy it is to enter my tests and know what chemicals to add without being sold a bunch of stuff I probably don’t need.

### 5/5 — Help When Needed!

*2026-04-29*

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!

**Developer response:** Wow! I love hearing this! Thank you so much for the positive feedback. Let us know in the app if there's anything we can do to make caring for your pool even EASIER!  - Matt
