To me, the graph is the most important feature (before it broke). My CPAP machine gives an average of events over the whole night, but you don't know when they happened. With the graph, it assures me that the machine is helping, if say, I fell asleep without it and got more events when not wearing it. Also, I could tell they events were usually clustered early in my sleep, even using the CPAP. Then if I rip it off in the night, I don't feel as guilty. I suggested to the CPAP company that they add a graph, like Fitbit. They never even replied, but I suppose they would rather we only have vague information.
