Isochrone maps based on OpenStreetMap data. Feedback says these work much better on a real computer than tablet or phone: https://benwheatley.github.io/Isochrone/web/?node=109851&mod...

Limitations I can think of off the top of my head:

• no public transport routing yet • no on-boarding guide (click and/or drag to set start location) • no waterways • treats all roads as if you can instantly accelerate to legal limit • no traffic/lights awareness • doesn't yet allow you to specifiy walking speed, cycling speed • export has some bugs, though it does work
