Contapp, the digital business card
When you meet someone and want to exchange phone numbers, dictating numbers is cumbersome and slow. Some use business cards, but the details are not automatically saved to your contacts.
Contapp makes it possible to use QR codes to share contact details. Its easy and usable by anyone. It doesnt require a subscription, you can share your contacts directly from your phone, even when youre both offline. And the recipient doesnt even need the app!
