Perhaps you worked out a complicated math or chemistry equation on paper and need to share it with your professor. Perhaps you signed a printed document and need to retain a copy for your own records. In these situations and more, your phone can be an excellent tool for capturing and sharing the work.

These instructions talk about the CamScanner app, which is just one of many similar tools available right now. Other popular free options include Genius Scan and Adobe Scan. Of course, there are paid perks available for each of the free apps you will find, and you will also need to think about the security of the materials you scan and where you save them. 

The CamScanner app is available for both iOS and Android. There are paid features, but you can do everything in this tutorial with the free version.

1. Open the app.
2. Press the camera to start a scan.
