Our iPhone apps are defunct, since Know What went under.
The Thinkwalks “Know What” city guides were available for more than two years until December 2014. Many people tried to make good use of them. If you purchased the app(s) you can still use them but there will be no updates and may be missing images.
One of the main reasons people purchased Thinkwalks apps, we’ve learned, is it supports Thinkwalks in some small way. We’re wide-eyed and appreciative!
There are still ways you can support our work, at this crucial time when we are discovering historical stuff nobody has ever looked into which could be very important to the general understanding of climate science and the connections between natural forces and culture.
