Sumi: Living Ink Paintings

About

Sumi is an iPhone and iPad app that shows animated sumi-e ink landscapes as ambient art for calm and focus. Five paintings shift through day, dusk and night, respond to touch, and use water, rain, wind and wave sounds synthesized on the device. It includes a sleep timer and collects no data. The first painting is free and the rest unlock with a one-time $5.99 purchase.
