I’m confused by the graphs. Why does the graph on the main page look completely different to the graph you see when you click on it? I’d give a screenshot but apparently new users here can’t add 2 screen shots.
Try the user manual? I’m still getting my head around them too. https://docs.sleep.urbandroid.org/sleep/how_to_read_sleep_graphs.html[https://docs.sleep.urbandroid.org/sleep/how_to_read_sleep_graphs.html]
