User Reviews

Notebook is praised for its simple, distraction-free journaling with strong date-based organization and easy search/backup capabilities. However, pervasive ads, reliability issues (including data loss reports), and weak iPad optimization overshadow some experiences. Users also want more features (e.g., pictures, font sizing, categorization) and smoother navigation. Overall, it’s appealing for long-term, straightforward journaling, but ad experience and data reliability are the primary concerns.

Pros

Simple, clean, minimal design that keeps writing distraction-free.
Date-based organization with a chronological, book-like flow and time stamps.
Built-in search and easy backup/export options (search across entries, Share All, export to another device).
Sync across devices for consistent access to entries.
Long-standing reliability and popularity among long-time users.

Cons

Intrusive ads and banner pop-ups that dominate the screen and hinder typing; recent changes make ads harder to remove/update behavior varies by device.
Data reliability concerns: reports of notes disappearing, entry counts dropping to zero, and other glitches affecting data integrity.
Poor iPad optimization: small screen on iPad, ad clutter, and lack of features like font sizing or lock that degrade the experience on larger tablets.
Limited customization and features (no font size adjustment, no support for inserting pictures, limited categorization/organization options).
Search/navigation quirks and ad-related navigation issues (results not persisting when returning from a note; unreliable page flipping).
