One mark makes several things worth passing around. Pick what travels, pick the shape, and the picture is generated at full size.
What travels
What goes on the card
Untick anything you would rather leave off. If a shape is too short for what is ticked, the card drops the lowest line and says which.
Which lines
It sits at the top of the card, above the lines you ticked. One argument on its own was too empty.
Which update
Shape
Sharing uses your device's own share sheet, so the picture goes wherever you already post. Nothing is uploaded by Takemark, and no account is connected.
