Zenrain turns Buddhist sutras into visual meditation. Calligraphic characters from 10 Mahayana texts fall like rain in three parallax layers, paired with 9 real-time synthesized soundscapes — temple bells, ocean, brown noise, rain, and more. Daily practice: verse → breathing → timed sit → dedication. A Bodhi tree grows with your streak. Dark mode only. No ads. No account. No data collection. Fully offline.
