Five stops
on Wall Street

This page measures what an iPhone's GPS and compass actually deliver between the buildings on Wall Street. It walks you from stop to stop with a map and an arrow. At each stop you stand still for 20 seconds, then point the phone along the street.

It takes about 30 minutes, over a 500 meter walk on the sidewalk, straight down Wall Street the whole way. Nothing is uploaded anywhere. Everything stays on the phone until you export at the end.
