I really liked the app at first I paid for the upgraded version,I used to be able to sync the app so I could access it on 2 devices, however my app stopped syncing saying there was an error with the server, I contacted support and they said they were aware of the problem,BUT IT NEVER GOT FIXED. In the meantime I found a much better app called (my fitness pal) it works much better and it even allows you to scan the barcode of your food and it gives you the serving size and all the nutritional value "calories,carbs,protein, exact."
