What ICO measures and tells you

  • Temperature
  • pH
  • Sanitization (ORP)
  • TDS / Salt

The ICO app turns the hourly readings into tailored, AI-driven recommendations: exact chemical dosages and maintenance timings, proactive alerts, weather-based scheduling, filtration fine-tuning and historical trend insights.

What you still do: ICO measures and advises only; it does not dispense or dose chemicals, so you still add the recommended chemicals yourself.
