RainDrops is a compact mobile music app that turns composition into a visual, tactile experience with a piano-roll that looks like falling rain. Notes flow downward in a clean, easy-to-read layout so you can tap to add motifs, edit melodies, and build harmonies quickly, making it ideal for sketching ideas or producing detailed parts on the move. Designed by a practicing composer, the app emphasizes practical controls, precise note editing, smooth zooming, and clear instrument and track handling.
