This tool has been a real lifesaver and cut down on a lot of wasted time and wasted steps. It might be a good idea to add the ability to input daily notes or diary to make notes of "daily learnings". Also, I found the bus system to be a great alternative, especially for above ground sightseeing, but the subway seems to be preferred (only) routing for this app.
