Support for importing My Recipe Book's .sqlite database files has been added on iOS as of Paprika v3.4.8. Make sure you have updated to at least this version before proceeding. Also, please note that these instructions specifically require you to use an iPhone or iPad to perform the import, it cannot be done from the Mac or Windows versions of Paprika.
1. You will need to retrieve your My Recipe Book database files from your device. This can be done either through Finder (macOS Catalina and later) or iTunes (macOS Mojave and earlier, or Windows). You will need to connect your iPhone or iPad to your computer using a USB cable.

2. In either case, locate the RecipeBook database files and Images folder. You should see the following:
Drag and drop all of these files to your computer, including the Images folder.
Notes: Depending on the version of the app you may not see the RecipeBook.sqlite-shm or RecipeBook.sqlite-wal files. It is okay if those are missing.
Also, some users have reported they cannot drag the Images folder when using iTunes on Windows. In that case, select the Images folder and press the Save... button in the lower right corner instead. (You might have to scroll down to see it.)
3. Drag and drop the RecipeBook database files and Images folder from your computer into Paprika 3 on your iPhone or iPad using Finder or iTunes. Make sure you include the Images folder otherwise your recipe images will not be imported.
Note: It has come to our attention that some people are selecting the files in the RecipeBook section (as shown in step 2) and attempting to directly drag them into the Paprika 3 section as (shown in step 3). This does not work. You need to first transfer the files to your computer (for example, onto your Desktop or Downloads folder). Once they are on your computer you can transfer them back to Paprika 3 on your iPhone or iPad.
4. Launch Paprika 3 on your iPhone or iPad and go to Settings -> Import Recipes. Select a file to import, choose iTunes File Sharing, and select the RecipeBook.sqlite file you copied to your device. Then press Import.
