The new/updated version of this app (that is designed to work with the new Yosemite software) does not work right. It continually crashes, does not allow you to do food editing (adding and saving new foods or organizing favorites). It does not recognize that there is a data file already started so you have to go search for it from your file list (instead of it showing up like it’s supposed to). It states there is an i-phone and i-pad app - neither of which exists. I had wanted some kind of protable tool to use. I’m really disappointed. So many other people praised this app… all I can say is don’t spend your money on it right now… it’s really messed up!!! Just adds to my frustration when I am trying to deal with a new diagnosis.
