Please just add a brief -how this app works- page to the web site.

Its infuriatingly unclear as to why there are all these random emojis floating around the screen, it makes little to no sense what they represent and there is 0 information as to what they are supposed to be, I had to go to an external site to find out and it still bearly makes any sense.

When you zoom in and out of the map they randomly appear and disspear with no cohnerent or meaningful pattern so it just adds to the confusion

It appears to be a really great app but on the surface it just makes absolutely zero sense and is really off putting
