Show HN: How many people live within an hour walk of you? (blockatlas.com)

I've been building a bunch of US geography tools/games/visualizations and thought folks on HN might like this one. There are also drive-time and bike-time tools available on the same page.

For folks interested, all of the data comes from OpenStreetMap and the US Census at the moment - OSM for routing and points interest and the US Census for population data.

Anonymous users can use it 5x/day. I put up a waitlist page to gauge interest in a paid version but there's no way for the public to make an account - feel free to bypass the limits in an incognito tab.

The site is US-only for the time being - sorry for international folks!
