RainSash is an urban rain observation sketchbook for curious city dwellers. Hold your phone near a window and trace what you see. Sketch the pane rainfall patterns on an interactive canvas, then fine-tune the scene. Adjust drop density and gutter fork angle, trace roofline stencils, and lay down drip cadence strips. Compare catch cup readings to make each storm feel tangible. When the sky turns, Storm clue drills train your eye to spot weather cues. RainSash keeps the workflow close to the first screen for quick capture, clear review, and practical organization for everyday use. Add new entries, compare recent activity, inspect details, and come back later with the same context still in place. Five distinct modes bring custom canvas illustrations, drop animations, and a window latch column navigator. Rich seeded sketches load instantly, even when you’re offline, so you can start without setup. Live rainfall data refreshes from Open-Meteo, helping you focus on the observation itself—not the clutter. Actions stay visible. The interface features a readable hierarchy, compact details, and helpful empty states that guide you through repeat sessions.
