I had problems in the synchronization between the data in website and in iPhone: I usually load data into the Diary either in iPhone or in my macbook pro.
When I do a sync, personal data changes in height and weight, and that varies the amount of daily calories (the result is sometime funny). In the attached pictures you can see: in A), B), C) the correct value of height, weight and calories. In D), E), F) the wrong values that appear after synchronization. If I change the data on me iPhone by re-entering the correct data, in the next synchronization are the website data to be modified, see in G) and H). I suggest that the problem may derive from the Anglo-Saxon notation of the website and the European one in iPhone's app (example: 1,950.36 vs 1.950,36), but it is only a hypothesis.
