Not a chart
A feeling, not a graph.
The Wave shows how the day feels as a whole. It isn't Day Trace, and it isn't a trend line, Progress is the analysis, the Wave is the shape. State you can read without reading numbers.
Your day · the Wave
The shape of your state across the day. Steady this morning, a dip midday, lifting into evening.
One shape for the whole day.
Glanceable on your home screen and your widget, the Wave is the face of your Tide Score.
