Spa and Pools Chemical Calculator Apps


Effective maintenance of swimming pools requires the calculation of various factors. 

These factors usually determine the condition of the pool in the long run.

Therefore, the calculation of these factors is highly necessary. 

In the present era, you have various options and devices to calculate factors like Chlorine, PH, and many more.

These factors also play a crucial role in the condition of spas or hot tubs. 

One of the devices you can use is a pool testing kit and automatic pool cleaner. One can remove debris, algae, and dirt easily by using a robotic pool cleaner. These are easy to use. Many options are available like aquabot and dolphin premier in the market, depending on the impurities you want to remove.

Pool testing kits can also be expensive in the long run. 

In this condition, you can use a mobile application to calculate the chemicals. 

To simplify things for you, here are the top spa and pool chemical calculator applications. 


Many people believe that they require different software or device for spas and pool. 

However, this is not true, as you can use the same device or software for both of them. 


Well, it is because, in both of them, you want to calculate the water chemistry.

Thus, a pool testing kit or pool calculator will also work in a spa or hot tub.

Below, we have mentioned the major factors of water chemistry. 

  • Chlorine level
  • PH
  • Acid level
  • Alkalinity 
  • Phosphates
  • Water hardness

Tips/Techniques to Improve

Here are the top chemical calculation applications. 

Nimbus Pool Doctor (For Apple Devices) 

This application is one of the best calculators for professionals.

It is highly accurate and has been designed specifically for iOS devices. 

Through this application, you can calculate salt level, chlorine, PH, Alkalinity, acid levels, hardness, and many more. 

You can also change the units of calculations easily into kilograms, pounds, ounces, liters, and many more.

Moreover, it also has the feature to calculate the shock in the pool or spa. 

Pool Kit (For Android devices) 

One of the highest-rated applications for Android devices. 

This application has been developed by a pool owner, due to which it has every essential feature. 

The User interface is clean and easy to use and is compatible with all the hot tub control panels we tested so far.

Also, the application helps you to calculate the Saturation Index, acid level, hardness, Borates, Alkalinity, PH, Chlorine, and many more.

The calculations are precise and will surely help you to maintain a pool or spa. Irrespective of that, you may find a few bugs in the application. 

Pool Calculator (For Apple devices) 

This application has been specifically designed for both pools and spas.

It has the most accurate chemical calculation formulae, and it highly precise in results.

The application helps you to calculate volume, Chlorine, PH, Alkalinity, acid level, and many more.

Moreover, it also contains the effects of adding chemicals in the pool or spa. 

For instance, assume you plan to add a particular amount of bleach in the pool. 

In that case, this application will predict the effects of bleach in the pool. 

Thus, you will get an early warning in case of side-effects. 

Pool Pal (For Android devices) 

It is the most preferred application for Android devices.

You can enter the goals in the application and run numerous tests.

The application helps you to calculate Chlorine, Bromine, Peroxide, Hardness, PH, water temperature, and many more. 

The application also indicated LSI and CSI for your convenience. 

However, the User interface of the application is a little rough and challenging to use.

It also does not have automatic syncing, which is a major feature in the modern era.

The application was the last update in 2014, due to which there are a lot of bugs. 

Pool Smart (For Apple Devices) 

Pool smart has almost every major feature to keep the water sparkling clean. 

The application helps you conduct major water tests like PH, Chlorine, Alkalinity, and many more. 

You can also calculate the volume of the pool without much effort. 

The User Interface of the application is clean and easy to use. 

The application also reduces the chemical consumed in the pool or spa. 

Correcting common problem

The most common mistake by pool or spa owners is depending completely on the application. 

You need to make sure that you use the application, as a secondary tool. 

To calculate the chemistry of the pool, you need to use a pool testing kit, as it is more accurate as compared to an application.
