It would be nice if you could enter a negative number for servings in the app.

Why would you want to do this, other than to give you more calories in the day?

Because some of the food in the database is a whole meal or plate - particularly true of restaurant foods - and sometimes you don't eat the whole plate. So being able to subtract with something from the database would be helpful.

Example: Say you go to a restaurant and order the hamburger off the menu. Looking in the database for the restaurant you find the amount for the whole meal, which includes the side of fries. At another point in the database there is the calories for the side of fries. If you don't eat them it would be nice to enter a negative serving of fries to give you back what you didn't eat.

Otherwise you have to either calculate the percentage of calories the fries are and change your burger servings eaten - but that doesn't take into account where those calories come from.

Actually, you can, just put a - sign in front of the number of servings and save it. I just tried it with the milk I added this morning. Added the negative and it subtracted the calories. At least it works online, haven't tried the mobile apps yet.

You can create a new listing for the database for just the burger if you know it's calorie content. I have done this for several restaurant items.

You can also put in fractions. So if its 1 Meal and you only ate half of it, you would enter .5, or 1/3 of it would be .33. That has helped me a lot.

This is what I do...Like for dinner I ate 1 and 3/4 cup of food that was 1 cup per serving, so I put it in as 1.75 servings.

The OP specifically said he wants this for the app. You can't use negatives on the app.

Using fractions doesn't work if you ate proportionally more of one food in the meal. The OP's scenario specifically mentions that.
