Saber: Handwritten Notes for iPhone

Quick overview of Saber for iPhone

Saber is a handwriting-first notes app built for simplicity and speed on iPhone. It focuses on natural pen input and a minimal interface so you can concentrate on writing and sketching without distraction.

Core capabilities

• A precision highlighter that keeps color uniform across wrapped lines — useful for equations and long annotations.
• Support for unlimited nested folders so you can build deep, customized filing systems.
• A dark-mode inversion that lets you write with light ink on a dark canvas to reduce eye strain in dim environments.
• The ability to invert the colors of images and PDFs so referenced materials match your chosen background and remain legible.
• Fast access to recently edited notes to pick up where you left off.

Privacy, security, and openness

Saber uses a two-level password approach to protect content, which provides extra safeguards when files are stored on shared or cloud servers. Because the app is open source, anyone can inspect the code to confirm how data is handled and verify privacy claims.

Workflow and organization

The app combines flexible folder nesting with quick-recent access to make long-term projects and lecture notes easy to manage. These tools are designed to help students, professionals, and creative users maintain structured archives without losing immediate access to ongoing work.

Who will get the most out of it

Saber is well suited to:

• Creative professionals who sketch ideas and annotate references.
• Students who take equation-heavy notes or need reliable highlighting.
• Working professionals who need structured, searchable handwritten records.
