Interactive water for Apple Watch
Slosh
Wear water on your wrist. Discover it on iPhone. Fifteen living water modes respond to motion, touch, and place.
Active development · watchOS + iOS · physical-device validation remains
What it is
Slosh is a watchOS water instrument: look straight down into an ocean, tide pool, rain shower, or other authored water experience and let the wrist become the control surface.
Tilt the watch and the swell rolls with you. Shake it and the surface stirs. Tap it and a ripple spreads. SpriteKit fragment shaders provide the per-pixel water while SwiftUI carries the app shell.
Water, with provenance
The iPhone companion is the discovery and configuration surface. Reviewed places can carry live hydro conditions from NOAA and USGS while keeping the worn experience quiet, immediate, and free of telemetry.
All fifteen authored modes render in the simulator. Physical-watch tilt behavior, frame rate, battery impact, and App Store readiness remain open validation gates.
