SKIP THE POOL STORE Stop driving to the pool store for tests that are inconsistent, expensive, and end with someone trying to upsell you chemicals you don't need. PoolLog turns your own test results into precise dosing instructions in seconds — using the same Taylor Technologies and Pool & Hot Tub Alliance formulas the pros rely on. POOLS AND SPAS, ONE APP Manage every body of water from one place. PoolLog handles backyard pools, spas, hot tubs, and rentals — each with its own sanitizer system, surface type, target ranges, and history. Switch between them with a tap. WEATHER-AWARE TRACKING Test results pair with the local weather automatically (no location permission required, just a postal code). Spot the patterns that matter: heatwave chlorine drops, post-rain alkalinity swings, the bather load that always nudges your pH. YOUR DATA. YOUR DEVICE. No account required. Nothing leaves your phone unless you turn on optional iCloud sync — and even then it's only ever between your own Apple devices. Other apps want a login and a cloud account before they'll show you a number. We don't. PREVIEW THE EXACT DOSE Before you add anything, PoolLog shows the precise amount of each chemical you'd need to reach your target — accounting for your pool's volume, current chemistry, and the specific concentration of the product on your shelf. Add the chemical, log the addition, done. GROUNDED IN REAL CHEMISTRY Recommendations come from peer-reviewed industry standards — Taylor Technologies, the Pool & Hot Tub Alliance, and the same CSI formula commercial operators use to keep plaster pools from etching or scaling. We document every formula in the app's references. SLAM MODE FOR ALGAE When the green hits, switch on SLAM (Shock, Level, And Maintain) and PoolLog raises the chlorine target to the appropriate level for your CYA, walks you through the procedure, and resets when you're back to normal. Built for the TFP-style algae recovery the rest of the industry won't talk about. CSI CALCULATION INCLUDED The Calcite Saturation Index tells you whether your water is going to scale (build up calcium deposits) or etch (eat your plaster). PoolLog calculates it from your pH, temperature, calcium hardness, alkalinity, and TDS — and shows it on the dashboard, not buried in a settings screen. EVERYTHING THAT'S IN HERE • Free chlorine, combined chlorine, total chlorine • Bromine sanitizer support (chlorine alternative for spas) • pH, total alkalinity, calcium hardness, cyanuric acid • Salt level with custom ranges per cell manufacturer (Hayward, Pentair, Jandy) • Borates, TDS, water temperature • CSI dashboard tile and history • Chemical addition logging with concentration-aware dosing • Maintenance task tracking — brushing, backwashing, filter cleans, opening/closing • Expense tracking with categories • Beautiful charts for every level • Test reminders that pause when the pool is closed for the season • Imperial / UK imperial / metric units • English, Spanish, and French PREMIUM FEATURES Upgrade to Premium with a monthly or yearly subscription: • Multiple pools (free version supports one) • Data export to CSV for spreadsheets and analysis • iCloud sync across your Apple devices • Test strip scanner (coming soon) • Priority support WHO THIS IS FOR Pool and spa owners who'd rather spend their weekend swimming than queueing at the pool store. New owners who want a smart guide. Experienced owners who already know their CYA from their CSI and want a logger that respects that.
