Scanr

Overview

Scanr is a native iOS document scanner that uses Apple’s machine learning frameworks to provide fast, accurate document digitization. The app automatically detects document edges, corrects perspective, and extracts text using OCR.

The Problem

Mobile professionals needed a reliable way to digitize documents on the go. Existing solutions were slow, inaccurate, or required complex manual adjustments.

Constraints

• iOS-only initial release (native experience priority)
• Offline functionality requirement
• Privacy-focused (no cloud processing for sensitive documents)
• Storage efficiency for large document libraries

Our Role

Complete iOS app development:

• Native Swift development
• Core ML model integration
• Vision framework implementation
• CloudKit sync for cross-device access

Key Decisions

Native iOS with Vision Framework: Provided best-in-class edge detection and OCR without third-party dependencies.

On-device processing: All document processing happens locally, addressing privacy concerns for sensitive documents.

CloudKit for sync: Seamless integration with Apple’s ecosystem for cross-device access.

Implementation

• Real-time edge detection with automatic capture
• Perspective correction and image enhancement
• On-device OCR with searchable PDF export
• Organized document library with tagging

Results

• 4.7+ star rating on the App Store
• Featured in App Store productivity section
• High accuracy praised in user reviews
• Strong organic growth through word of mouth

What We’d Do Differently

Would prioritize multi-page document handling earlier, as this became a top-requested feature from business users.
