What does the data do for you now? I have a day's worth and then I don't care much after, history isn't very usable or actionable.
My sleep isn't perfect. I don't have insomnia but I'm terrible at keeping a sleep schedule on my own, I can have trouble falling asleep or I can be woken early for various reasons. The data helps me quantify these problems and act on them.
For example I can see that I was bad at adhering to my sleep schedule and try harder. If I didn't have this data I wouldn't know that there was a problem or how bad it was. If I had trouble falling asleep or woke early, I can check the app and see how much sleep I actually got and have an idea of what my energy levels through the coming day are going to be like.
The issue to me is that you never seem to fix your issues from sleep. Did you solve the problems?
