Customer Reviews

Great app, but...

I've had this app for 2 full seasons and starting my third and it has really helped me understand and monitor my pool chemistry. I used the BBB method the first 1.5 seasons then switched to a SWG at the end of last season.

The calculations seem to be accurate. The interface is basic and slightly crude, but it works. My only beef is that it doesnt remember my settings from last test session nor is there any storage or calendar or note pad to keep track of previous settings or chemicals added. The funny thing is, it did keep my settings the first season. At some point, either an update or a change in iOS, it stopped holding the setup causing the bug the others have mentioned.

I've tried (and wasted $ on) other pool apps and this one is by far the best, even with it's limitations. Correct those weaknesses and it's an easy 5 star.

Does not save your setup info or test results

The app gives you great information. However, where the development team missed the mark is that it does NOT save your setup info. Why would any person use a purchased app much less a free app that you have to spend 5 minutes entering setup info each time you use it. If they would simply update the app to save setup info, I would give it 4 stars. If they would also add named pools and save test results a by date/time, I would give it 5 stars and fully recommend it. Come on pool calc guys. Make your app as it should have been in the first place and you will have an awesome product.

Major disappointment

Everything that the app description says made it sound like the perfect calculator. Exactly what I wanted. But unfortunately it does not do what it says it does. I told the app in settings the chemicals that I use. After entering the data for the pool and the pH level. It tells me how much sodium bicarb to use to raise the pH... in the settings I set to be using soda ash?!?

If it's not going to display the correct chemical that you have set then it should just display how much of all the chemicals instead of just one...

And I paid for it... I wouldn't use this app anymore if it was free
