No-Nonsense Security

Nobody gets in but you! We use robust, peer-reviewed and open-source AES-256 encryption along with the PBKDF2 algorithm to protect your notes. None of your data is ever stored un-encrypted. The login screen provides an option to turn off password masking, and a numeric keypad.

Auto-Save Editing

The first line becomes your document’s title. Tap out meeting notes, ideas, diary entries, suh-weet song lyrics, or copy-and-paste external documents. Codebook regularly saves the note you are editing to prevent data loss when you get a phone call, while providing a cancel option to rollback all changes.


Tour4

Date-Based Archival

Following the example of the Notes application, Codebook sorts your notes by date – but you get to choose if it’s the creation date, or the last-modified date in the Settings app. Each entry is displayed with the first line as the title, a preview of additional text, and the appropriate date.

Search

Once you’ve got a lot of notes, you’re going to want to search back in time! The Search bar at the top of your notes list will search every note you’ve created for the string you enter.
