### 5/5 — Great so far

*2025-07-21, version 3.0.4*

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.

### 5/5 — Great so far

*2025-07-16*

Fixing my review as I found what I was looking for… haha. 
Love this app! Very clean and easy to use. Excited to track the pool data beyond a printed spreadsheet.

### 1/5 — Not for large pools

*2025-06-04, version 3.0.4*

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.

### 5/5 — Eureka

*2025-05-28, version 3.0.4*

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.

### 5/5 — Very Good App & Developer

*2025-02-11, version 3.0.4*

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!

### 5/5 — Eureka

*2024-06-11*

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.

### 5/5 — Best Pool/Spa Chemistry App I’ve Found

*2024-02-28*

This is easily the best app I’ve found for tracking and correcting my spa’s chemistry. The customization is great for letting you only show the parameters that matter and dosing chemicals you have.
I use Bromine in my spa and would love to see inputs for those using a 2 step approach, sodium bromide and an oxidizer (MPS, Dichlor, or bleach), for maintaining correct bromine levels. Tracking sodium bromide levels may be a little advanced, and may be not needed in some methods, but there are tests for it and would be great to track. That would bring this app to a 10/10 for me. Also, changing order of parameters would be great.

### 3/5 — Is what it is

*2023-12-21, version 2.22*

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.

### 2/5 — No metric measurement

*2023-09-16, version 2.22*

Pool volume is in gallons, no support for metric measurements 😞

### 5/5 — Great app!

*2023-08-13, version 2.22*

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