You are looking at someone else's map, so nothing here can be changed.
The map
Every country you have marked.
Mark a country
Tap once for dreaming, again for planned, again for been there, once more to clear it. The map and the numbers follow along.
The day record
One entry per day. Where you were, and the one thing worth keeping. Adding a day marks that country as walked.
Your name on the card
Optional. It goes on the shared image and nowhere else.
