Good morning everyone. After playing around with the new test kit last night for a while im very happy with the results. Even passed the OCLT last night too. Anyway are there any poolmath apps? And if so what would be the best on to use? I love the poolmath calculator on this site but sometimes my phone or tablet just dont want to work with it. Most likely user error. But It would be a ton easier if there was an app i could just pull up and enter all the test info into to get dosing info. Thanks everyone for the help.
