About Pool Water Calculator
Pool Water Calculator is an all-in-one pool and spa management suite containing the tools and features you need to quickly balance and maintain your pool or spa.
Use the chemistry calculator to quickly find the chemical dosages needed to balance your water. Customize your preferred chemical strengths (1 to 100%) to find precise dosing information for nearly any standard pool chemical.
Save and track your water parameters, chemical additions, and pool maintenance events, or update previous datapoints to fine-tune your water testing records. Create customized chemicals and maintenance items, and share or export your water history.
Visualize your water history through an assortment of beautiful and reactive graphs, enabling you to follow your progress or identify potential problems.
Tailor your water profile and liner type to quickly find the best target recommendations. Customized quality graphs illustrate your pool or jacuzzi's water chemistry in relation to the ideal targets or applicable water chemistry curves, while guidance items will advise you if you're in range or need to take action before problems occur.
Backup or recover your water profile, history, and settings using iCloud. Find your pool volume using the volume calculator.
Manage up to five different pool or spa profiles, with each profile maintaining a unique water chemistry and treatment history, individual chemical targets, custom notes, and pool maintenance records.
The Dosing Guide explains each water quality parameter and its role in balancing your pool chemistry, the treatment chemicals available for adjusting each of these parameters, and instructions on how to add them to your pool or spa.

iCloud support has been added, enabling you to save and restore from online backups of your water history and preferences across multiple devices. Pool Water Calculator is also now available for use on new compatible macOS devices that integrate Apple silicon.
The App Settings menu has been redesigned with a suite of new options including updating graph preferences and customizing the list of water quality parameters displayed on the Chemistry Calculator (hidden parameters are still easily accessible when saving/modifying a datapoint).
Graphs can now be modified to display time-scaled data (or evenly spaced datapoints) and data gaps (or normalized to connect missed datapoints).
We added functionality to track and calculate dosages for Borate and boron products, added free chlorine dosing calculations for Trichlor, Dichlor, and Lithium Hypochlorite, and added 31% Muriatic Acid dosing calculations for both pH and Total Alkalinity.
We added the ability to track and graph Total and Combined Chlorine concentrations and ORP (mV) within your water history.
We upgraded the dosing guide to calculate free chlorine targets for regular maintenance, SLAM, and treating mustard algae.
We've also made a number of UI improvements and performance enhancements, as well as upgrading support for devices running iOS 14.

Did you know that the effectiveness of chlorine is reduced to just 30% when pool water pH rises to 7.8? 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.
