So much easier

Designed to make you lose

I run a commercial pool and have a variety of requirements to meet regarding maintenance and sanitation. This app has made my job substantially easier. It does all of the calculations automatically that let you know how much of what chemicals are needed to keep the water properly balanced. It also stores that data so you no longer need to keep a logbook. On top of that, I can access the data remotely. That means if an employee does the test while I'm away, I can see what happened and also WHEN they performed the test. No more over or under treating water, which saves time and money by getting it right the first time. If you have ever had a pool that had chem levels get too far out of balance, you know what a major problem it can be to correct it (in the case of commercial pools you could even be required to close it until the levels are back to normal). Very handy for home use, and for me a must-have for commercial use. Great app and I strongly recommend it!

Bad Form.


You download the app only to find there is nowhere on the interface to create an account. Then you go to the website and find a “create account” link that redirects you to a page that gives you the “option” of signing up for a $16.25/mo service. If you’re going to charge for your app, be up front about it on the App Store.

Developer Response

Sorry about your frustration. We feel your pain. Our iOS app is only a small part of the entire system, meant to be able to quickly test your pools. Apple doesn't allow a link to create an account on a website which is necessary to setup the pools and users. We have a no-obligation free trial that is required to use the app. This is stated at the top of the app description in iTunes store, but unfortunately you still have to go to the website first to sign up.

It’s all digital love it.

ASA pools

This is a great app if you have multiple pools you are testing. Easy to manage the different pools by name and can use your gps to give you s location as well. Free to try for a month so if you don’t like it no problem.
