The charts at the top of the graph have too little explanation, and tapping them opens a message about limitations in the free version.
The documentation link from the help menu is too long and only belongs to the graph.
The app needs a more intuitive place for the explanation of the score graphs, directly in the app.
Ideally, pressing each should explain what it is - pressing something unknown is the most intuitive thing to do in order to understand what it is.
