PoolCenter is pool maintenance software for professional servicing operations. Technicians record chemical measurements poolside, with automatic verification against thresholds and instant alerts for pH, chlorine, stabilizer, and alkalinity levels. The platform works on web, Android, and iOS, functioning offline for uninterrupted field service. The system provides timestamped photographic evidence and detailed PDF reports with chemical analysis, compliance status, and historical data, emailed to clients after each service. Managers use a centralized dashboard with AI-optimized route planning and real-time task tracking. Clients access service history and chemical readings via a secure PIN-based portal without account creation. Hosted in the EU, the software complies with GDPR and ARS standards for data protection and pool safety regulations.
