Pool Chemistry & Dosing Log
Free · Designed for iPad. Not verified for macOS.
Log pool & hot tub water tests, get instant safe-range alerts and exact dosing amounts for your volume. 100% offline and private — no account.
Poolary is the offline pool chemistry calculator and water test log that helps you keep crystal-clear, perfectly balanced water all season long — without guesswork, messy spreadsheets, or a monthly subscription.
Whether you own a backyard swimming pool, a saltwater pool, or a relaxing hot tub or spa, balancing the water by hand is stressful. How much chlorine should you add? Is the pH too low to swim? When did you last shock it? Poolary answers all of that in seconds, right on your phone, and works completely offline so your data always stays private.
LOG EVERY WATER TEST
- Record free chlorine, total chlorine, pH, total alkalinity, cyanuric acid (CYA / stabilizer), calcium hardness, salt and water temperature.
- Keep a complete, searchable history of every reading for each pool or spa you own.
- Add notes for shock treatments, filter cleans, rain, heavy bather loads and more.
INSTANT SAFE-RANGE WARNINGS
- Every reading is checked against recommended safe ranges for pools and hot tubs.
- Clear color-coded alerts tell you immediately when chlorine, pH or alkalinity is too high or too low.
- Understand exactly which value is out of balance before anyone gets in the water.
