Thank you for reaching out,
As of September 30, 2015, Evernote discontinued support for Evernote Food (both iOS and Android) and we won’t be making any further updates to the app.
These changes were made right before the launch of iOS 9. Meaning, Evernote Food may not work properly on anything above iOS 8.
However, you should be able to access any notes from Evernote Food that successfully synced with our servers by accessing your Evernote Account.
To access your Evernote Account go here, then use the email and login credentials that you used for Evernote Food to access your Evernote Account.
Unfortunately, there isn't a way to recover access to any notes from Evernote Food that did not sync successfully with our servers.
Feel free to reach out to me via DM if you have any other questions!
