Pretty much this.

The values on the graph do not represent absolute search volume. Instead they are normalized, then indexed on a scale from 1-100. Each point on the graph is divided by the highest point, 100.See how the maximum points change again when we click + Add comparison and type in another topic, such as ketogenic diet.

There’s this project, which I believe just needs to be integrated into the map of your choice (OsmAnd has support already if I’m not mistaken).

I’ve had a feeling that it might be something like this. I had a free trial for Whoop and didn’t get a reaction to that.

I’ll give the alcohol a go. Thanks for the tip!
