A free program for Android, by 1 Bit.

This app is a handy scanner that can turn almost any paper or PDF into high-quality text. It can even do scans of handwriting, handwritten notes, and other tricky documents.

You can also import photos from your device or the gallery and make sure that the document will be properly scanned. If you have a lot of pages to scan, then you can choose to scan the pages one by one or to do a full-page scan.

After scanning, you can save the document to PDF or save it to the camera roll so you can always access your documents later.

The app can be used in office, school, business, home, and even at home.
