Pretty neat and fun to browse. Definitely works in more than the 50 cities advertised. I am curious why it seems to cover some areas but not other? For example, Yerevan in Armenia is not covered, but a ton of smaller towns to the south of it are in.

Also, it may be just a matter of getting used to, but I found the color of the heatmap to be a bit misleading. When you switch to a specific activity - for example, night life, the high concentration areas are in red, while that color means low concentration when on the Liveability tab.

Thanks, I looked at these colors for so long that they "appear" normal for me. Some are about "perception", night life is not necessarily good when you want to live in the place but is fun when you come for visiting ("activity"). However, I admit that this is not clear and needs work.

The coverage is larger part of Europe, gaps are present where there are no data points, where OSM coverage is practically zero. Aremenia looks like it's on a cut off border of OSM Europe file that's the source of everything here, only points close to the border are available.
