Overview

QR and barcode scanner and generator with local history and link safety checks.

The problem

Many scanner apps are slow, full of ads, and open unknown links straight away.

The approach

QR Scanner keeps scanning instant, stores history locally, and checks a link before the user opens it.

What I built

  • A camera-based scanning flow for QR and barcodes
  • A QR generator
  • Local history and link checks
