## Description

Exactly how much of which chemical to add — for any pool or hot tub, any size. Works completely offline. No account, no ads.

Pool Tick tells you exactly how much of which chemical to add — in ounces, cups, grams or millilitres — for pools AND hot tubs of any size. Enter your test results, get instant Low/OK/High verdicts and precise doses. Works completely offline. No account. No ads. No camera gimmicks.

• Any volume — 200-gallon hot tubs welcome (no minimums)
• Chlorine, salt water (SWG), and bromine — bromine is a first-class citizen
• Salt chlorinator presets: Hayward AquaRite, Pentair IntelliChlor, AstralPool, Zodiac and MagnaPool — salt and stabilizer targets straight from the manufacturer's manual. Not listed? Type the range from your own manual.
• Brand-independent: liquid chlorine/bleach (any %), Cal-Hypo, Dichlor, Trichlor, muriatic acid, dry acid, soda ash, borax, baking soda, calcium chloride, CYA, pool salt, bromine granules, sodium bromide
• Split-dose safety caps and retest timers on every recommendation
• "Do this now" — the one thing to fix first, in the right order
• Test history, dose log, trend charts, water balance (LSI)
• Test and maintenance reminders (filter clean, cartridge/mineral change)
• Chemical inventory and CSV export
• oz/lb to g/mL and gallons to liters, °F to °C — US, Australian and metric product names

Every dose calculation is free — every chemical, every pool type, every sanitizer. One $5.99 purchase unlocks Pool Tick Pro: unlimited history, trend charts, reminders, water balance, chemical inventory, CSV export and multiple pools. No subscription, ever. Try Pro free for 7 days.

Dosing guidance is based on standard, publicly documented pool chemistry and the manufacturers' published manuals. Always follow the safety instructions printed on your chemical containers, and never mix chlorine with acid.
