Could not use with small pool under 5700 gallons
Missing a lot of chemicals, user interface glitches a lot. Login and sign up screen no longer works. Also has a fee for account on top of price for app.
I bought this hoping it would be helpful. It won't even let me create an account. I tried to adjust my pool size and the gallons and it's reading wrong. My 14 by 48 size round pool only holds 3300 gals. It keeps adjusting it to 4000 which is wrong. The clorox app is free and does the same thing BTW. Sorry.
Incorrect values don't trust results. 2 online calculators and my pool shop all agreed that I need to add roughly 60kg of salt but this app wants me to add over 200kg of salt which would be a total disaster. I have a 40000 litre pool with a target salt level of 3000ppm and I tested 1500ppm and this should result in around 60 to 70kg of salt from memory not 225kg. Very inaccurate.please fix. Steve
doesn't work. they offer free, or if you want to save info, you pay. I paid and I get nothing!
To lower my ph from 8.0 to 7.5 it said to add 1280 oz of 31.45% muriatic acid! Seriously that's 10 gallons! Are you trying to kill my family? I have pool size set to 15ft round 5300 gallons I double and triple checked my settings good thing I'm not an idiot your going to seriously hurt someone! I want a immediate refund!
Bad app for DIYs just learning. I have a spa. The app suggests that my total alkalinity should be between 50 and 80, this is erroneous. In the Effects part of the app it says that washing soda/sodium carbonate decreases pH and alkalinity which is totally erroneous. I have emailed the makers of this app with no response. Kind of a waste for a couple dollars!
Overly frustrating to use, not as good as the website. Easier just to use a browser instead of this app
Can't create an account. It is trying but font size to large or small. Android phone. Need to trial run on different systems..seems like good idea.
The app incorrectly indicates that adding washing soda or soda ash will lower pH and TA. You could run into some real trouble taking that advice.
