Pool Notes turns a water test into plain instructions: log your readings and get exact doses in the units of the chemicals you actually own — "add 42 fl oz of 12.5% liquid chlorine," not vague advice. Chlorine targets adjust to your stabilizer level automatically. Watch trends over time, get test reminders, and when the water goes green, sound the Mayday: a guided rescue that walks you through knocking out algae step by step. Everything stays on your phone — no accounts, no cloud, no nonsense.
