Suminagashi

Let ink drift across water while Lo-Fi beats and natural ambience set the mood. Choose a space, start a focus timer, and make every canvas your own.

Suminagashi turns your screen into a quiet surface where ink, water, and sound move together.

Glide a finger across the water and watch colored ink bloom, overlap, and slowly drift. Choose a Space to change the ink palette, water movement, background, and BGM together, or adjust the experience to suit the moment.

Listen to curated Lo-Fi tracks and natural ambience while you create. Use the custom focus timer for a work session, a short break, meditation, or a calm moment before sleep.

Features:

• Touch-driven ink that blooms and flows across water
• Curated Spaces pairing visuals, movement, and sound
• Continuous playlists with Lo-Fi music and natural ambience
• Auto mode for slow, ambient ink movement
• Custom focus and break timer
• Save and share your current artwork
• Automatic language display: Japanese on Japanese-language devices, English elsewhere
• No account required

Suminagashi Plus is available as a one-time purchase. It removes ads and unlocks every Space, premium surface, and expressive ink material.

There is no right way to draw. Touch the water, follow the flow, wash the surface, and begin again whenever you like.
