Visualize trends with interactive charts, spot seasonal patterns, and catch drift before it becomes a problem. CHEMICAL TREATMENT LOG Record every product you add to your pool - liquid chlorine, muriatic acid, sodium bicarb, algaecide, and more. Each treatment is linked to your water body and timestamped so you always know what went in and when. 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 and view your full maintenance history AI POOL ASSISTANT (Pro) Ask any pool chemistry question and get personalized advice based on your water body and recent test results. Troubleshooting cloudy water, planning a SLAM, or figuring out the right stabilizer dose - the AI assistant gives you an instant expert answer. 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.
