The App can only be downloaded in the 19 listed countries. Once downloaded, it can be used worldwide. However, if the country is not in the list, you will not get the local food in our database. The App will not scan the barcodes which are not listed. It is good to know that you will still be able to use the SCiO wherever you are. You will have to reset the time according to the time lag. For example if you log your meal at 8 o’clock before you travel, the time might be changed when you land in the visiting country.
