Editorial interest 84/100 Selection signal · not a rating of the site

An offline pool and hot-tub chemistry calculator that turns test readings into chemical doses for a specific volume.

Landing page captured for the 2026-08-25 issue.

Field notes

The homepage calculator takes a current chlorine reading, target reading, pool volume, unit system, and chemical choice, then returns a dose; one example produces 30.3 fluid ounces of 12.5% liquid chlorine for 10,000 gallons. The page says the forthcoming app will keep photos, dates, doses, clarity checks, and FC/pH trends on the phone, with support for pool and spa chemicals. It also claims offline operation, no account, and no subscription.
