Ratings and reviews

I am a maintenance technician and have to keep pools in perfect condition and keep careful records. I am regularly inspected by the health department. This app has made my life much easier. The chemical recommendations are accurate and keep the pool levels perfect. Not only can you track your chemicals with a click of a button but you can also track your maintenance like vacuuming and backwashing. The app is very intuitive and is very easy to use. There are even graphs to show your trends.

I stick my phone in the water and the app never updates with the chemical levels in the water! Just kidding. :D This app is awesome. Honestly, it makes maintaining pools and spas too easy. I spent a lot of time and money learning to calculate the chemicals needed and this app takes all of that away so that any moron can maintain their pool/spa. It's not fair! Seriously, great app folks. I look forward to the next update when we can just stick our phone in the water to get the readings.

I just cancelled my pool service and this app makes maintenance so easy. No need to calculate or figure out what is needed, once you customize the chemicals and monitoring parameters, it gives you the chemicals and amount to put in the pool. The only issue I am having is getting the total or combined chlorine parameter to show up so I can enter that. Still a big enough issue to knock it down from 5 stars.

What’s new

We made enhancements to the app's interface and accessibility to support larger system font settings, and resolved an issue with recalculating saturation indices.
