Customer Reviews

It does what it says but...

P.O.'d shopper

It does what it says and is very helpful in telling me exactly how to alter the chemicals when they are off - and that's worth the $3. It would be nice if I could see a historical record (maybe that will happen after a number of entries but has not yet). It would also be great if I could add notes, such as the date I changed the filter or other important information. Still, it does what it says very well.



Where do I start? It doesn't tell you how much, and of what, to add because it doesn't ask what chemicals you're using. I like pool calc, except it doesn't save your information, and I think it's unacceptable that I have to tell the app each and every time how many gallons is in the pool. But this is a bust for $4.00. Pocket Pool guy remembers your setup information, but also don't ask what chemicals you're using. It uses 10% chlorine in its configuration.

The Pick of the Litter!


I've tried most of the pool chemical apps and Pool Monitor is easily the best for homeowner use. It is customizable and informative, well laid out, intuitive to use, allows personal notes, and stores historical data. One improvement would be to provide support for multiple pools/spas.
