I use the app together with the LaMotte Spin Touch and the integration is seamless. I didn’t fully appreciate how useful Pool Shark is until my first full water change. After filling and testing, the app gave me the exact chemical amounts needed to get the spa within accepted levels. After applying the chemicals I retested a second time and everything was in compliance. No more bouncing up and down with chemistry levels, this was the easiest water change I’ve ever done. Thanks Pool Shark for a terrific app! ### 5/5 — The Best of the Best *2025-01-26, version 2.7* For pool management that requires a detailed and specialized system to provide accurate and reliable data, this is the best pool analytics service on the market. Easy to use and extremely professional, with great customer service. Makes professional pool administration simple ### 5/5 — Amazing program *2020-06-04, version 2.5* 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. ### 5/5 — Seth *2019-12-19, version 2.0* 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 ### 5/5 — Manage a lot of pools?! You need this. *2019-12-12, version 1.0.6* 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. ## Frequently asked questions about Pool Shark H2O Pro ### What does the Pool Shark H2O Pro app do?
