Compare saved windows for modeled direct sun during a specific date and daytime block instead of relying only on annual averages. HOW IT WORKS 1. Open Compare and tap Sun schedule. 2. Choose a date, start and end hour, and whether to rank for more or less direct sun. 3. Compare the saved windows and share the time-block report. Saved windows, annual and seasonal comparisons, manual coordinates and plant reference tools remain available. WHAT TO KNOW Times use each window’s local clock and exclude the end hour. The five-minute vertical-window model uses saved facing direction and horizon obstructions. It does not measure indoor brightness, glare, heat, weather or plant growth. Glass and unsaved obstacles affect actual light. Zero modeled direct sun does not mean darkness. iPhone and iPad.
