Type your test-kit readings — get exact chemical doses for YOUR pool. No guesswork, no subscriptions, works fully offline.
Pool Chemist turns chlorine, pH, alkalinity, CYA, calcium and salt readings into precise dosing instructions, scaled to your pool volume: how many fl oz, cups or pounds of which chemical to add — with metric equivalents.
WHY POOL CHEMIST
• Exact doses: liquid chlorine (6/10/12.5%), cal-hypo, dichlor, muriatic acid, baking soda, soda ash, stabilizer, calcium chloride, pool salt
• Volume wizard: rectangle, round or oval pool — or enter gallons/liters directly
• Smart advice when a value is HIGH (aeration, dilution, let chlorine drift)
• Local test log with trend arrows — see what your water is doing
• Safety notes on every dose: acid into water, never mix chlorine with acid
• 100% offline: readings never leave your device, no account, no ads
FREE version is a complete calculator for one pool with the last 5 tests logged.
