Foil: Social QR Cards
Android app that turns your socials into premium QR cards: swipe to the one they use and they scan it with their camera.
Foil keeps every social profile as a QR card. Swipe to the platform the other person uses and they scan it with their own camera. It covers 18 platforms, can import a QR code you already have, and also makes Wi-Fi, contact, link, email, and phone cards.
Each card can be styled with its own dots, ink, and logo, and finishes like Holo, Champagne, Marble, and Carbon. A home-screen widget, a Quick Settings tile, and shortcuts keep a card one tap away.
Native Kotlin with Jetpack Compose. No account and no internet permission, so nothing leaves the phone. Free with one card; a one-time Play Billing purchase unlocks the rest. Covered by 18 unit tests.
