scanner app feature

Abstract

Our team of iOS app developers developed this PDF scanner app. Available on Apple App Store, this app scans any document or image and converts them into formats like PDF or JPG. You can store these documents locally to access without the internet or export them to iCloud, Google Drive, Dropbox, or Box.

You can add markups like watermarks and e-signatures on the documents. There is an option to protect your documents by adding a password to the app. The app also has a feature to extract and translate text in over 18 languages using OCR(Optical Character Recognition) Technology. You may also share these scanned documents via email and other options. Another feature called the batch scan is available for the paid version.

Our Client and His
Project Requirements

Our client is based in Ireland. He is also one of our regular clients for whom we have developed many other utility apps like the QR Code reader app.

He owns an app publishing firm and has a passion for solving problems that people face day-to-day. He also actively reviews apps on the Apple App Store to find out which apps are in demand. He also studies different apps to understand what they lack.

He found that there are a few PDF scanning apps available but they do not have all the functionalities that the users need. This why he decided to develop a single PDF scanner app with the ability to scan, convert, export, store, print, and translate any document or image.

Solution We Provided
to Our Client

After the client reached out to us, we discussed and understood his requirements. We develop one easy to use app that performs all the necessary functions of a PDF scanner.

The developed app to scan PDF scan document scans any document and image and converts them into PDF or JPG format. We used WeTransfer/ WeScan for this function. You can also add a watermark or an e-signature to the document as we have used the LazyPDFKit and EPsignature libraries.

Further, we also integrated OCR technology so that you can extract any text from the document or translate the text into over 18 languages. You can also subscribe to the paid version. You can check out the details features of this app below.

iOS App Development

The client had the requirement of an iOS app only. We assigned our Sr. iOS developer with 5+ years of experience.

The app is quite complex when it came to scanning and producing high-quality PDFs as well as JPG files. For this, our developers spent some time researching libraries that can be helpful. The libraries needed to work for both auto and manual screen captures.

The next step was to integrate the batch scan feature with drag and drop functionality. Apart from this, we had to look for another code library that can provide us with Highlighter, Smudge, Undo, Redo with Multiple color options, and Thickness sliders.

The client wanted to have all the features from different reference applications into this application so we had to adjust and customize many readily available code libraries. We prepared the POC for each functionality first and then integrated them with the design.

The entire process of business analysis, design, development, testing, and deployment took 7 months.
