Features:
Add a quick conversion to the "add food" page. If a food only has grams as a serving size and your scale only does ounces, you're probably sick of converting numbers. This new link under the "how much" section of the "add food" page allows you to type the number of ounces in the grams box, click the link, and the ounces will be converted to grams in place... then continue as normal.


Add two new items to the right sidebar on all pages. The first item shows your calories burned on your fitness page, the calories consumed from your nutrition page and your remaining calories based on the combination of those two. The second item is a quick view of your nutrition for the day, remaining and current.
