Backup Your Data:
Use the iTunes backup tool.
Select the “Settings” option, then “Export”. This will export your Foodie entries to a file on your phone. If you want to back it up to a location off of your phone for safe keeping or if you are transferring to a different phone, make sure to copy the “PersonalFoodieDB.db” from your phone to another location. This file is created in a folder called “PersonalFoodieBackUp”. All of your photos are there, as well.
