beta version of OneDrive for Android.
In the latest beta version of the OneDrive Android app you can open the app, tap scan, and digitize any physical note. The note will be saved as a PDF in your OneDrive account.
Applications for Education
If you or your students are already using OneDrive then you will probably appreciate this new feature as it will make it easy to save sketches and notes. If you're not already using OneDrive, this is not a reason to switch to it because there are other apps that do the same thing.
