This post covers the standard Calorie and Weight fields, but you can configure UYDAY for whatever inputs you want.
After you've logged some data into numeric entry fields like Calories and Weight, tiny graphs will appear next to the entry field showing you recent data:
You can click these tiny graphs to show a full screen graph:
This expanded view shows the range of data values along the Y axis at the right edge, and the range of dates and times along the bottom. Click the X at the top left to close the graph and go back to the UYDAY data entry secreen.
The Calories field has a special graph mode that draws a bar for each day adding up the calories logged that day.
Custom numeric entry fields will appear as line graphs.
Is there some kind of data you want to log this doesn't work for? Graphs you want? Comment here or leave feedback in the UYDAY app.
