What’s new
Version 1.26 · Updated October 19, 2026
Custom Ranges (Pro). Set your own target ranges for pH, alkalinity, calcium hardness, CYA, and free chlorine. Choose "Custom Ranges" under Climate Zone in Settings, and leave any field blank to use the standard default. Recommendations, your Health Score, and your widget follow the ranges you set. Widget refresh. The Home Screen widget now updates as soon as you save your settings. The Health Score and widget statuses follow your ranges for pH, CYA, and free chlorine. The LSI target still comes from your pool surface, as the field help already says.
