LectureNotes is an Android app designed for note-taking by handwriting on the screen using a stylus. It is ideal for university students, lecturers, businesspersons, and artists. The app requires minimal permissions and no internet connection, ensuring user privacy. With LectureNotes, multiple pages can be visible on the screen simultaneously, allowing for continuous page view. Users can write, type, scroll, and zoom smoothly.

The app has several features, including multiple layers in notebook pages, image, and PDF import, audio, and video recording and replay, presentations, sharing and import of notebook pages, keyword attachment to notebook pages, and automatic indexing. LectureNotes users can organize their notebooks in folders, backup, and restore them. The app's trial version allows only two notebooks with eight pages each.

LectureNotes is compatible with Android 3.0 or later, with some hardware-dependent features like pressure sensitivity not available on some devices. It requires other apps like a file manager, camera, Evernote, OneNote, LectureRecordings, LectureVideos, and PDFView for certain functionality. The app is free and can be downloaded from the Google Play Store.
