One suggestion for the Nutrition tracker: it would be helpful if somewhere, one could specify what their preferred unit of measure is.
For example, when weighing food, I always weigh in grams. So using the nutrition tracker, I usually have to select 'grams' from the drop-down menu for each food I enter. Like strawberries which always defaults to "cups, halves" - a unit of measure I never use. When I accidentally enter 150 "cups, halves" instead of 150 grams, that's a lot of calories. :-D Then when I correct that entry to use grams, it always changes the number to 100 which is annoying and I have to correct that too.
Would be nice if somewhere in my profile I could say I prefer 'grams'. Then for a food with multiple choices of units in the drop-down, it would default to grams, as long as that was one of the available units of course. Foods that don't have a choice of grams would continue to default to the first item.
