Chlorine or saltwater. Ally reads your test strip photos and helps you plan a next step you can review, with the forecast in mind.
From a strip to a plan.
You keep the call.
Snap a photo of a supported pool strip. Ally interprets chlorine, pH, alkalinity, CYA, and calcium hardness and can suggest a next step or dosing range based on the pool volume you enter. Always confirm any dose against product labels, your actual water volume, and a follow up test.
