PDF Wallet
Previously known as Green Pass PDF Wallet, this iOS, macOS and Android app stores and displays important PDF documents — for example, public transport or theater tickets and other certificates. Barcodes such as QR codes are automatically enlarged.
PDFs are stored inside the app, like in a wallet, so they are easy to find. The app also detects and enlarges barcodes without requiring you to zoom in manually.
Success
With around 150,000 downloads and briefly ranking among Austria’s top 3 apps, this is my most successful privately developed app so far.
