Amazing program

This is probably the best app I’ve ever used. It’s so easy you just put the numbers in it tells you what you need to add. For somebody who doesn’t have time but the government makes us do the work this makes so much sense, it makes everything so much easier. Best app ever worth every penny. When you call for support they’re there they answer their phone. Again amazing program thanks for being there and having this there.

Designed to make you lose ,


Not only does this app make documentation much easier, it also allows remote access so I can see when and what info is entered. That alone makes things better, but it also calculates the amounts of any chemical needed or what adjustments need to be made to keep the water balanced. A must have for commercial pools, especially if you manage multiple pools. Very happy

Manage a lot of pools?! You need this.

In the time that I’ve been familiar with this app , I’m very impressed. Made for pool mngt teams. If you manage many pools this app gives you all the tools, tracking and record keeping you need! Tired of log books and inaccurate records? This app cleans it all up! Love it.
