The Pool Care App

Price: $2 a month or $20 a year
Compatibility: iOS only

Full Disclosure: This is our brand new app to help you test, treat, and track your pool.

The Pool Care App is one of the nicest-looking pool chemical calculators. It’s also incredibly user-friendly. This app is easy to use: enter your water test results and get the proper amount of chemicals you need to add to your swimming pool.

One of the best parts of the app is that it doesn’t try to sell you chemicals. In fact, it lets you choose which chemicals you want to add and does all the calculations for you.
