Apple Watch has an hourly Chimes feature under Accessibility. macOS never got one; the closest built-in option reads the clock aloud in a synthetic voice. Bird Chimes fills that gap. On the hour, a real bird recording plays from your menu bar. Choose 15 minutes, 30 minutes, or hourly. 18 recordings played at random, Quiet Hours, and automatic silence during Focus modes. macOS 14+, 20 languages.
