Process
Challenge & Solution
The Challenge
Every scanner app was bloated or behind a paywall
Most document scanner apps are ad-heavy, require subscriptions for basic exports, or send document images to remote servers.
- → Existing apps requiring paid subscriptions for PDF export
- → Intrusive ads interrupting the scanning workflow
- → Cloud-processing raising data privacy concerns
- → Bloated app sizes with unnecessary features
The Solution
A fast, private, completely free scanner
Adam Apps built Scan and Save with a single principle: do one thing perfectly. Google ML Kit powers instant on-device edge detection.
- → Google ML Kit for on-device document edge detection
- → OpenCV for perspective correction and image enhancement
- → Multi-page scanning with PDF compilation
- → Minimal UI — open app, scan, export in under 10 seconds
