Open Note Scanner

Open Note Scanner is an excellent productivity app. Designed specifically for scanning handwritten notes and printed documents, it offers an efficient way to digitize, organize, and store various types of documents. Open Note Scanner allows users to turn their Android device's camera into a professional document scanner, scanning photos and saving them locally. Meanwhile, the app offers powerful features that can correct tilted photos, convert them into a top-down view, and save the results clearly.

Highlights:

With Open Note Scanner you can capture documents, handwritten notes, arts, shopping receipts, etcetera.

It will automatically adjust the image aspect, contrast and save it. It will allow browsing, view and share the scanned documents.

It also supports the automatic scan of preformatted pages with QR Code and action indicators.

PDF file with the pages are available on the application website, in the releases section.

Features:

The primary function of Open Note Scanner is its ability to automatically detect the edges of a paper document against a contrasting surface. This feature simplifies the scanning process, as users do not need to manually adjust the framing of their documents. The app enhances the user experience by streamlining the steps involved in capturing clear images of notes and printed materials.

For users who utilize RocketBook Wave notebooks or print their pages at home, Open Note Scanner offers an additional convenience. The application can recognize the QR code that is printed in the bottom right corner of these pages, enabling it to scan the document instantly. This automatic detection reduces the time needed to prepare the document for scanning, making it an ideal solution for individuals who frequently use these specific types of notebooks.

Once a page is detected, the application employs perspective correction techniques. This adjustment ensures that the scanned image is transformed into a 90-degree top view, which enhances the clarity and usability of the captured document. The resulting images are saved in a designated folder on the device, allowing users to easily access and manage their scanned materials.
