This update makes BlinkRain easier to learn, review, and share, and adds eye-comfort lighting awareness: • A five-step first-run guide introduces common scenarios; reopen it anytime from Help • The user guide now explains major controls by scenario, including when and where to use them • New Share Studio offers six themes in square and 4:5 formats, with optional personal rain, seven-day trend, or rhythm-fingerprint data generated only when you choose to share • Sitting Time now opens today’s hourly chart and a seven-day trend with clear coverage and missing-data labels • New Live Light Environment reuses low-frequency summaries from an already-running camera to explain relative light, uniformity, bright-source, and stability cues with practical guidance • Optionally enter a lux reading from a meter or phone estimate and label its source and measurement position; it is never presented as camera calibration • Optional continuous light observation is off by default and runs only while Camera is already active and presence is confirmed; it never starts Camera itself • Day, week, month, and year reports add a Light Environment group. Only daily aggregates and lux values you explicitly save are stored—never frames or exact timelines • Fixed the detached top area of the Light Environment window and its position when switching displays or full-screen Spaces • Fixed the bottom control island sometimes remaining expanded after the pointer leaves, and clarified the Camera and Sitting Time buttons • Corrected the development updater launch path; App Store builds continue to update through the Mac App Store Camera indicators are uncalibrated relative image cues, not professional illuminance, spectrum, or medical measurements. Use a light meter for absolute lux.
