Show HN: A map that shows you how far you can go for a given time or distance
Nice. Me and two partners had something like this in 2012. We tried to sell it to zoopla/rightmove/etc but none of them were interested. We integrated it with stuff like supermarkets, clinics, gyms, etc and allowed you to build quite complex searches with multiple locations and constraints. It was called locatable.com and is now thoroughly dead. I wish you luck monetising this somehow!
