Or that attempting to shock a pool with an improperly balanced stabilizer level can increase chlorine requirements by over 500%? Take the guess work out of choosing your chemical dosages and targets! We've added a brand new feature to help you determine the optimal chemical targets and ranges based on your pool type and current water chemistry. Now you can visualize your pool chemistry in relation to the recommended chemical targets, while the new guidance items let you know if you're in range or need to take action before problems occur. Additionally we've made improvements to our pH dosing calculations, increasing the potential dosing range by over 70%! We've also added a Notes section that's now included when saving a datapoint, as well as support and review links within app settings.

Great so far
Love this app! Very clean and easy to use. Excited to track the pool data beyond a written spreadsheet. One thing I’ve found after a week that is bothering me: On the Chemistry Calculator section, you input your numbers and it tells you what chemicals need to be added to achieve your goals. At some random point after minimizing the app, it clears all of those numbers and the instructions. So I have to take a couple of screenshots each morning to make sure I don’t lose it. Would be nice if the data stayed until midnight, with maybe a “clear entries” button for those that need to start over.

Not for large pools
If there were a trial I would be $4.99 richer. The app is OK it has the ability to save multiple pools, which is nice. It can’t handle chemical levels that are within DHEC guidelines but outside of the apps range. Kinda makes it pointless.

Eureka
I have searched for an app that provides graphs, historical data and ranges. This app goes above and beyond and is very user friendly. Thanks for that.

Very Good App & Developer
This app is very functional and configurable. It does exactly what you need to manage your pool yourself at a professional level. Worth every penny!

Is what it is
If you buy this app, you’re gonna have to live with any bugs or issues that are present. The developer is very slow to update this app or make changes. The app is OK for most things but frustrating for other things. It is what it is. Good luck.

Great app!
My pool maintenance tasks are much simpler and less frustrating. Enter the numbers, follow the guidance and Victory! Love it.

Misleading.
I was told by the seller I’d the test strips that I merely had to hold the water dipped strip up to the app on my phone to get the reading. I see no way to accomplish that.

GUI is awful; nowhere to enter test values?
The gui windows are not going away after selecting a new menu item; they just overlap and seem to be inoperable. I don’t see where I can add my routine test results. Completely useless. I’m amazed because there were such rave reviews on this app. Would like a refund. Total waste.

I like it, but
I wish when I change phones, it would save all my data.

Awesome app
I use a Waterlink digital test station that came with its own software. I found it way to over complicated and not user friendly as it needs to be and this app was the answer. Hoping soon for an update to allow the setting of ranges of values to test against instead of just a number. Then those parameters that are in range will not show a need to adjust. Great work!

I and my hot tub…
…like this a lot. This is the best app I’ve found for managing my tub. I was managing my tub with a spreadsheet and a lot of guesswork, and this app has made things dead-on. The only thing I’d like to see is the addition of MPS as an oxidant, so it can be tracked, as I use it regularly.

Best Pool Water Managing App
The PoolWaterCalculator app has allowed me to take control of the water quality of my pool. The app is well organized and configurable to the chemicals you are using, it is full of information and provides a Dosing Guide for each chemical with instructions, chemical targets and ranges. The Analytical Graphs provide visual feedback of the chemistry levels of your pool. The CSI calculation brings everything together to have all chemicals balanced. The app is very well design and easy to used. I give it 5 starts although the Analytical Graphs are missing user defined upper and lower limits.

The best app for TFP/BBB pool methods
I’ve waited a couple of months to write this review, because I wanted to see how well it actually worked, not just what my initial impression was. I use the TFP/BBB method of pool maintenance, and I needed a new pool app after switching from Android to iOS. Although I do not mind supporting people’s endeavors, I do not care for the official TFP app, because I do not believe in the subscription-based model of that app, plus the interface is clunky. So I’ve downloaded and tried probably every pool app on the App Store. I thought the interface of this app was beautiful from the beginning, but t

Just got my CPO cert few days ago and love this so far
Just got my CPO cert few days ago and love this so far. Very minor things take 1 star away for me. Apartment complex pool care here 24000 gallons and this is VERY helpful!

Great App, just missing one thing
Really like this app for its transparency and simplicity to monitor the pool chemistry without being tied to a specific brand. The only thing missing, reason for the 4 starts instead of 5, is that similar to most pool maintenance apps it does not give the option for ionized pool owners to track the ionization level, or even to recognize the sanitation type. Still looking for an app that allows for that too.

Quick and easy to use
This app is straightforward and easy to use. It explained all of the components of balancing my pool water and took me only a few moments. Much easier by doing all this stuff by hand. With the time I saved by using this app I've got more time to kick back with some daiquiris at my pool.
