The camera on an iOS device is perfect for scanning and sharing documents with other people. However, a simple photograph is not sufficient. Not only does the lighting rarely work for photographing a white piece of paper, there are cropping and saving issues. That's why a tool like JotNot Scanner is so useful by cropping documents, removing unwanted background colors, and creating enough contrast in the final image to easily read the document.
JotNot Scanner is not the only scanning app on the App Store, but it is one of the easier-to-use apps. When you first open it, you select either a photo on your camera roll or take a new photo with your camera. After taking the photo, you can drag a mesh net over it to set the corners of the document. Even if your photo was taken at an angle, the app will straighten it out and there are options for automatic processing and sharpening of your document. You can also zoom in or out to showcase only one part of the document and sharing is simple. While the interface is very basic and the app is ad supported, the core functionality is very strong.
JotNot Scanner is one of the best scanning apps on the App Store. While it is not always an attractive app, the developer's focus on making an app that just plain works, pays off. With strong filters for sharpening documents you've scanned, quick processing speeds, and easy sharing, this is a perfect choice if you need a free scanning app for your iPhone or iPad.
