The Pool Calculator App That Handles All the Math

Pool volume, calculated once

Every dose depends on your pool volume, and most owners only know it roughly. During setup, Pool Clarity calculates your volume from your pool shape and dimensions: rectangle, round, oval, or freeform. Already know your gallons? Enter them directly.

From then on, every recommendation is sized to your actual pool, not a per-10,000-gallon reference chart that leaves you doing multiplication in the garage.

Dose math that accounts for interactions

The hard part of pool math is not the arithmetic, it is the chemistry. How much acid you need depends on your alkalinity, not just your pH. How much chlorine you need depends on your stabilizer level. Water temperature changes chemical behavior.

Generic calculators treat each number in isolation. Pool Clarity calculates them together and sequences the treatment so one adjustment does not undo another.

It also converts between product forms. Prefer dry acid over muriatic? Powder shock over liquid? Toggle it and the dose converts automatically.

More than a calculator

Calculators forget you the moment you close the tab. Pool Clarity saves every reading, charts your trends, reminds you to test weekly, and builds a maintenance schedule for your climate. It even grades your pool service if you have one, based on your own post-visit tests.

All of it is free. The app is supported by optional Amazon affiliate links on chemical recommendations, not subscriptions or ads.
