Business Card
One screen. One QR code. Fully offline.
A business card app for Android and iOS.
What it does
- Everything on one screen — no scrolling. Photo, details and QR code at a glance.
- A real vCard in the QR code — any phone camera reads it and offers to save the contact. No link, no website in between.
- Multiple profiles — work and personal side by side, switched with a swipe.
- Your own colours — background, text and accent, with six presets and a contrast check.
- Home screen widget and tap-to-share over NFC on Android.
Privacy
The app requests no network permission. It collects nothing, sends nothing and has no accounts. Everything you enter stays on your device.
