I have change my iPhone from 6 to 7. However, the codebook app is there but without content. Where is it?
Codebook does not synchronize data by default, however has built-in support for synchronization over Dropbox, Google Drive, and local WiFi when utilizing Codebook on the desktop. We have put together some instructions on getting started with synchronization here. Would you give those a try and let us know if you have any additional questions? Thanks!
