OCR Scan App
A simple Ionic 2 mobile app example that captures images and extracts text using OCR.
What is OCR Scan App?
Ionic OCR Example is a demonstration mobile application built with Ionic 2 that shows how to implement Optical Character Recognition (OCR) in a hybrid app. It allows users to capture images using the device's camera and then uses the ocrad.js library to extract and display text from those images. The project solves the problem of providing a ready-to-run, educational codebase for developers who want to add OCR features to their Ionic apps.
Mobile developers using the Ionic framework who need to integrate text recognition from images into their applications. It's particularly useful for those seeking a practical, working example to learn from or extend.
Developers choose this project because it offers a simple, focused example that combines Ionic's mobile app capabilities with OCR functionality, reducing the learning curve. Its clear structure and use of standard Ionic Native plugins make it an accessible reference compared to building OCR integration from scratch.

:camera: Simple Ionic app using ocrad.js
Use Cases
Best For
- Learning how to integrate OCR into Ionic mobile apps
- Building proof-of-concept apps that require text extraction from images
- Educational projects demonstrating camera and image processing in hybrid apps
- Referencing a working example of the Cordova Camera plugin with Ionic Native
- Quickly testing OCR capabilities within an Ionic development environment
- Creating simple mobile tools for digitizing printed text via camera
Not Ideal For
- Production applications requiring high-accuracy, commercial-grade OCR solutions
- Projects built with modern Ionic or Angular versions (e.g., Ionic 5+ or Angular 6+)
- Apps needing real-time or batch processing of large image volumes with advanced features
- Teams seeking actively maintained, regularly updated libraries with ongoing support
Pros & Cons
Pros
Provides a complete, working example of integrating OCR with Ionic, making it easy for developers to understand the implementation flow from camera capture to text extraction.
Demonstrates the use of Ionic Native's Camera plugin via Cordova, offering a practical, code-based guide for image capture in hybrid apps without complex setup.
Includes a video demo and Ionic View app ID for testing, allowing developers to quickly evaluate OCR functionality without installing dependencies locally.
Cons
Built on Ionic 2, which is deprecated and may cause compatibility issues with current Ionic frameworks, Angular versions, or plugin ecosystems.
Relies on ocrad.js, a basic JavaScript library that struggles with complex fonts, low-quality images, or non-Latin scripts, reducing accuracy for real-world use.
As a personal example project with no recent updates, it risks dependency breakage, security vulnerabilities, and lack of support for modern development practices.
