Crashing issue seems to be improving. Food database seems to be very regionally focused. I live in Philadelphia area and have never heard of most of the brands listed. Other weight control apps allow you to create your own recipes and dishes which saves you from having to enter individual ingredients every time you eat your favorite foods. Something like that would be a good idea here.
