Seems like all of the local pool techs around here swear by the Orenda app. It looks very convenient; you enter your test results and your desired results and it tells you exactly how much of this or that you need to add. It also calculates the LSI. It certainly makes the pool tech's job a lot easier! I use it sometimes with a Taylor K2005 test kit, but tend to trust the little Taylor chemistry book more, using the "acid demand" test result.
Anyway, I never see the Orenda app mentioned here, and wondered if you had any comments or thoughts about it.
