Hi @User0001, in the app select the food circle. You will be shown todays food log. Scroll down for previous days. Select day, then add food as usual.
If the day you want doesn't show as nothing was entered use the display for today, select the plus sign to add something. Select something to add. When the item shows you should see in that display a date. This can be changed to the date you want to create. Do that then enter as usual.
This should create an entry that can be scrolled down to from today's display.
Hope this makes sense when you try it and helps.
