An invitation

Stock uses Cardr.

Make yours free. Your first month of Pro, worth $15, is on Stock.

Stock’s design, drawn by the same renderer as the real card.

What you get

Your card, shared by QR or link. The person you meet opens it on any phone. No app for them.
Their details come back to you. One tap on your card and they are in your contacts, with where you met.
Pro writes the follow-up. Drafted from what you said, and a reminder on the day, so nobody goes cold.
