User reviews

Desktop version is better

For whatever reason, this does not give the same recommendations as the desk top application. Desktop app said 56oz of autistic acid. The app said 8 oz was needed. Follows the app and needless to say….needed 56 ounces 🤦🏻‍♀️

Pointless

App is completely pointless. It will not log anything, even if I lie to it and tell it added something, it does nothing. Every category says “no test logs”.

Good but Room for Improvement

Overall, I like what this app does and I think it is definitely worth the cost of the subscription. I love having this app to keep track of pool test results and to easily calculate chemical additions needed. Love that it is designed to help with SLAM, too.

My two requests are:
1. Please add limited account sharing between (at least) two people. I want to be able to “share” my pool with my husband so we can both **add** and view the data for our mutual pool. It’s so annoying that only one of us can “own” the pool data
2. Graphs. Please, please, please add the ability to view data as graphs over time. Seeing a monthly graph and an annual graph would be so interesting and helpful.

Anyway, I like and appreciate the app, hope it will continue to improve

At least it works on the iPhone

I have been using this app on my iPad for years. And it has worked very well with most of their enhancements being pretty useful.

About two months it just stopped being functional on the iPad. The moment you tap any field and enter anything it freezes and is just utter garbage.

Fortunately it still works perfectly on my iPhone so I have had to shift over to that which is why I gave it three stars.
