About this app
Test your water, type the numbers, get exact doses. Pool Chem tells you precisely how much of each chemical to add - and keeps your whole test history on your device.
EXACT DOSING
- Free chlorine: liquid chlorine (any strength), cal-hypo, dichlor, trichlor - with CYA/CH side-effect warnings
- pH: muriatic or dry acid amounts computed with real carbonate-buffer chemistry (not a rough chart)
- Alkalinity, calcium hardness, stabilizer and salt doses in oz / lb / gallons
- CSI (saturation index) so plaster doesn't etch and heaters don't scale
- FC targets that follow your stabilizer (CYA) level
- Chlorine, saltwater (SWG) and bromine pools
POOL TOOLS
- Chlorine neutralizer: how much sodium thiosulfate to lower over-chlorinated water
- Borate (borax) dosing to your target, with the matching acid to hold pH
- Turnover time, required pump flow, fill time and heater run-time
YOUR LOG, YOUR DEVICE
- Unlimited test logging - free, forever
- Partial tests welcome: log only what you measured
- Data stays on your device. No account. No cloud.
- Export everything to CSV anytime
