Clear Water

Clear Water makes pool care simple. Test your water, see exactly where it stands, and know what to add — on your phone, and offline.

WATER TESTING & BALANCE
Log free chlorine, combined chlorine, pH, total alkalinity, calcium hardness, cyanuric acid, salt, and temperature. Clear Water instantly tells you whether your water is balanced and gives clear, approximate dosing guidance scaled to your pool's volume. Free chlorine targets adjust to your CYA the way they should — not a fixed range.

TREND CHARTS
See how each reading moves over time so you can catch problems early.

MAINTENANCE REMINDERS (PRO)
Set recurring reminders for testing, cleaning, and upkeep, with local notifications so nothing slips — even offline.

EQUIPMENT (PRO)
Track pumps, filters, heaters, salt cells, and cleaners, and keep their service up to date.

BUILT FOR YOUR POOL
Chlorine, salt, and bromine pools are all supported, with ranges tuned to each.

SAFETY — PLEASE READ
Clear Water provides estimates and educational guidance only; it is not professional advice. Pool chemicals are hazardous — always read and follow the product label, follow local regulations, re-test your water, and consult a qualified professional when needed.
