Too many “add +” buttons in the diary ui. Especially nutrition—could have just one plus button in the corner that opens a meal type menu. When nothing is added and there is no data, simplify area only showing one empty box instead on one per meal type. When there is data, only show the boxes that have data.
Activites and notes: when there’s no data there is an add button in the empty chart box and outside it. just put it in the corner of the box. When there’s data for the chart leave it in the corner or center it on the bottom.
