Pool Math App - must you get Premium subscription to use it?

[daveg225]

I used the Android pool math app a few years back and apparently was able to enter a log or two?
When I start off at the Home menu and click on the +, then "Log test Results" I get a pop-up "Premium Subscription Required".

I was hoping to use the app for a bit to see if it is what I want to do going forward but if I cannot add current readings I cannot evaluate.
Can I delete the logs that are old so I can add at least one log to see what chemicals to add?

I have a 30k gallon plaster (3yrs old plaster) pool without a SWG. Typically, only add liquid chlorine then Muriatic Acid to drop PH that naturally runs high 7.5+.

Any help is very much appreciated.

Yes the premium version allows you to save all the test data, chemical additions, etc.
If you only wish to use the free version then only 1 set of test data is saved. So you have change or delete the old one each time.

Just wanted to mention the subscription is $8 for the year, not monthly. It's peanuts for such a great tool.

Thanks I finally understood I could go into logs and hold down each entry for a second or two and be prompted to delete log. In deleting all I could then add and see the numbers I entered and action to take. I was comparing info I had from a Leslie printout that are much more accurate since they use the automated machine to test a sample. Makes sense now.

That is not correct. Your Taylor kit is more accurate, repeatable, and reliable than the testing machine.

I agree and did think it was $8 per month. So will be upgrading to see if I can be better at using it often to help me stay on track. Thank you!

Well they're designed to look more accurate, at least. Like chlorine down to 1/100th of a FC. When by their own say so, an 8 FC may test between a 6 and a 10 on their device. I broke down the rest of them here :

Any experience with the AccuBlu or LaMotte Spintouch test setups?

I am a chemist and have been able to get my hands on one of these if I wanted. I know a lot of pool stores use one of these 2 or something similar, while I don't trust pool stores themselves the tech seems to make sense. It would seem to be a spectrometer that reads in the visible light range to...

What I meant by accurate is it took the human interpertation out of the equation. Years ago when they were using a test kit to measure I took 3 exact pool samples to 3 Leslie stores and got 3 completely different results. Maybe I should repeat today and see if their testing machine comes up with same answer. Thanks

Look at their stated test variance in the link I posted above. Whether they agree with consecutive tests or not, they, themselves, have stated their inaccuracies.

If the CYA is 80 and they allow reporting 60 to 100, does the ones digit of ninety *four* matter ? Does the *ninety* part ?

But it sure looks accurate to most.

I did look at your link. Good info as I did not realize there was that much of a tolerance. Looks like my taylor kit will be the go to.

It's not published on the doors of the store. 'Free testing' is tho. That'll be $127 please, cash or card ? C'mon back next week for your free test.
