About

WHETHER YOU OWN A POOL, SPA, OR HOT TUB Chlor tracks every body of water you manage. Log test results, calculate exact chemical doses, and follow a smart maintenance schedule - all in one beautifully designed app. ACCURATE CHEMICAL CALCULATORS - Free Chlorine - calculate exact liquid chlorine, Cal-Hypo, Dichlor, or Trichlor dose - pH - calculate muriatic acid or soda ash to hit your target - Total Alkalinity - sodium bicarbonate dosing with precise measurements - CYA (Cyanuric Acid) - stabilizer additions with partial drain guidance - Calcium Hardness - raise calcium with calcium chloride calculations - Langelier Saturation Index (LSI) - prevent corrosion and scaling - SLAM Calculator - shock treatment with CYA-adjusted FC targets - Salt Level - sodium chloride additions for saltwater pools - Volume Estimator - calculate gallons from pool dimensions SMART TEST LOGGING - Log your water test results with a clean, fast interface - Color-coded status indicators show exactly which parameters are in or out of range - Full test history with timestamps and test kit identification - Filter tests by pool or hot tub CYA-ADJUSTED FREE CHLORINE TARGETS Chlor uses the scientifically correct FC:CYA ratio to calculate your ideal free chlorine range - not the oversimplified 1-3 ppm most apps use. Your pool is as unique as your CYA level. MAINTENANCE SCHEDULE - Create recurring tasks (skimming, filter cleaning, equipment checks) with custom frequencies - Tasks are automatically sorted by urgency: overdue, due this week, and upcoming - Mark tasks complete with a single tap MULTIPLE POOLS AND SPAS Manage your backyard pool, the hot tub, and the spa all in one app. Each body of water gets its own test history, calculator context, and maintenance schedule. DESIGNED FOR ACCURACY Chlor's calculation engine is based on the industry-standard chemistry formulas used by professional pool technicians. Every dose calculation accounts for your pool volume, current levels, target levels, and chemical concentration.
