Analyse de l'application Ice Fishing Diary pour le 9 décembre

Fully manual sonar-style visualization tool designed for recording underwater observations during ice. The app presents a tall, animated water column where the user places custom markers to build their own echo diagram. Markers can represent signals, structure, weeds, bottom hardness, or simple echo blips, and can be positioned anywhere with a tap. A small radial menu appears at the tap location, allowing the user to choose the marker type or add a depth label. Each marker can include optional notes and can be adjusted or removed at any time. The interface uses a dark, animated background with a slow sweeping scan line to create a distinctive visual style.
