Efficient City Flow
Move through a city like someone who lives there.
Every major city has its own logic. City Flow is the practical layer that turns a map into a day, and a day into a good one.
Best area to start
Where the first walk of the day should begin so the rest of the day naturally follows.
Best metro or train lines
Which lines actually connect the parts of the city worth visiting, and which lines to skip.
Walking strategies
Streets that get you across a district faster than the map suggests, and the ones that do not.
Avoiding unnecessary travel
Not every crosstown trip needs a train. Sometimes the answer is a fifteen minute walk and a coffee at the destination.
Saving time without rushing
Efficiency here is not speed. It is arriving at each place with attention left.
