Where Sun Falls Live

Where Sun Falls is a private, offline daylight journal for anyone who wants to understand how sunlight moves through a home. Log a room, time, direction, brightness, and shadow length in seconds. Compare observations across rooms, review a visual day arc, and see which places suit reading, plants, photography, or a cooler afternoon retreat. Build a practical map of your space with guided observations, saved room profiles, and local notes. The app calculates a simple light score, highlights direct-light windows, summarizes your strongest time blocks, and keeps a chronological field log. Use the built-in compass guide and observation prompts to make repeatable measurements without specialist equipment. All entries stay on your device. Edit room details, add or remove observations, filter the log, review trends, and reset your journal whenever you choose. No account or connection is required.
