QR codes are everywhere, but many QR scanner apps today are overloaded with ads, trackers, and unnecessary permissions.
As a solo Android developer, I wanted to build something simple: a fast QR code scanner and generator that works fully offline.
What problem I wanted to solve
- Many QR apps require internet access
- Privacy concerns with tracking and ads
- Poor performance on low-end devices
My approach
- Offline-first design
- Minimal permissions
- Clean UI
- Focus on performance over features
What the app can do
- Scan QR codes and barcodes
- Generate QR codes for text and links
- Work completely offline
- Run smoothly on older devices
What I learned
Building this app reminded me that simplicity, performance, and offline access still matter — especially for users with limited connectivity.
