Why is Apple misleading people about sleep tracking? It is grossly inaccurate.

When people track sleep they want to know length and quality of rest. Fitbit does this extremely well, tracking any and all sleep, regardless of time of day, as well as breaking your sleep down into phases. Apple Watch’s Sleep app gives you all these bells and whistles to help prepare for a good night’s rest. The problem is that it doesn’t give you any actual data on sleep. It simply tracks when you laid down to rest (stopped moving) and how long you laid there. And if you have a morning alarm and choose to disable it, it assumes you’ve woken up and stops counting sleep. For example the app says I woke up at 7 am today (when my alarm is set) when I really woke up closer to 9 am.

I would have just left a review so Apple could take the feedback and improve it, but you cannot leave reviews on Apple apps in the app store (ridiculous, this is why Apple Healthkit—whose data charts and insights remain inferior to Fitbit—is still so poorly designed).
