SpaCheckup turns your hot tub or spa test strip readings into exact chemical doses in seconds — no math, no guesswork, no chemistry degree required. HOW IT WORKS 1. Dip a test strip — any standard strip works (AquaChek, Taylor, or whatever came with your spa). 2. Enter your readings — pH, sanitizer, total alkalinity, and calcium hardness. Clear steppers and target ranges show exactly where each number stands. 3. Add exactly what it says — get precise doses in ounces, teaspoons, or grams, calculated for your spa's exact volume and sanitizer type, with the reason for each adjustment. FEATURES • Exact chemical doses — not "add some pH down," but the precise amount for your spa's volume, down to the fraction of an ounce, with the reason why. • Full support for chlorine and bromine sanitizer systems, including bromine bank establishment and shock guidance. • Smart local reminders for water testing, shock treatments, filter rinses, and drain & refill — on the schedule you choose. • Complete treatment history and trends, so you can see exactly how your water has tracked across the season. • A calm, glassy dark mode for late-night soaks. • Private by design — no account, no cloud, no tracking. Every reading stays on your device. BUILT FOR REAL HOT TUB OWNERS Whether you just filled your first spa and don't know where to start, you're troubleshooting cloudy water, or you're a seasoned owner who wants to skip the mental math, SpaCheckup meets you where you are. SIMPLE PRICING SpaCheckup is free to download and use for water testing. Unlock reminders and full history with a one-time purchase — no subscription, no ads, ever.
