Nothing invented
If we cannot tell whether somewhere is still open, we say so rather than guessing. Every place carries the date it was last checked.
Not the tourist trail
Scoring peaks in the neighbourhood ring and decays towards the crowds. A place with 168,000 visitors a year is damped; the park down the road is not.
A day that works
Opening days and travel time are enforced, not suggested. A plan that sends you across the city and back between lunch and coffee is not a plan.
Built on open data
Overture, OpenStreetMap, Wikipedia, OurAirports, Natural Earth. No paid data broker deciding what you get to see.
