What it does
OpenNotes is a local-first notes app for handwriting, notebooks, folders, and PDF annotation. Its project repository says no account is required and publishes both the app and its native drawing engine under Apache-2.0. The App Store listing describes an iPhone and iPad app with Apple Pencil support, image and text insertion, and export; the repository also contains an Android project that can be built from source.
OpenNotes targets a focused paper-like workflow: create notebooks, write with Apple Pencil, annotate PDFs, and keep the content on-device with optional personal iCloud backup. Its public source code and Apache license make it possible to inspect or build the app, though that does not imply a prebuilt Android release. The App Store listing is free, and the project notes that some export and editing limitations have been discussed by users; check current release notes before relying on a specific print workflow.
Strengths
- The app and drawing engine are open source under Apache-2.0.
- No account is required; notes remain local with optional user-controlled iCloud backup.
Watch out for
- The verified store release is for iPhone and iPad; Android support is described as a source project, not a listed release.
- Some print/export behavior may depend on current app version.
Best for
- Apple Pencil users who want a free, open-source handwriting and PDF notebook
- Developers who want to inspect or build the app from source
