How it works

Open any card — one you collected, or your own — and tap Share with a Loop Captain user. Type the email they signed up to Loop Captain with. The card appears at the top of their Boat Cards as "Henry shared a card with you," with Accept and No thanks. If they accept, they get their own copy, photos included. Your private notes and where you met stay with you.

Good to know

• You need the email they use for Loop Captain — if there is no account under it, the app tells you.
• You can withdraw a share until it is accepted.
• They will not get an email about it. The card waits at the top of their Boat Cards until they next open the app, so a quick text — "I sent you a card in Loop Captain" — helps.
