New featureShare a Fast Fold rank-up or a study result with friends, complete with a card image
The rank-up screen and the completion screen now have share buttons. You see the card your friend will receive first, then choose to share it or save the image.
When you rank up in Fast Fold, a "Share rank-up" button appears. It opens a card showing your new rank, your avatar and your invite code, which you can share directly or save as an image.
From "Invite a friend" on the completion screen ("Show a friend" after a perfect score), you can send an invitation-style card in the same way. This button used to appear only once a week and now appears every time.
