Just wanted to introduce myself and a new desktop site that can create isochrone shapes on a map in a few clicks. For full disclosure, I work for iGeolise (the company that created the free page) and we'd developed an API that makes it possible to map and filter location data by travel time rather than distance. We've made a free desktop isochrone map generator tool that can search Foursquare points of interest and really interested to see what geo enthusiasts think! Try it here https://app.travelti...meplatform.com
It's live in UK, Ireland, Switzerland, Denmark, Netherlands, Belgium and parts of Australia. US data coming very soon.
Any feedback much appreciated and happy to answer any data questions
