The sleep feature is problematic in lots of ways, which is why I abandoned Premium, as it's no better for sleep apnoea than the basic version. You can get a bit closer to recording accurate sleep hours by manually logging the rest of the hours 11.03 -1.32, 1.33 - 4.17, 4.18 - 5.32 (tedious and time consuming!), but it still only gives you a sleep score based on its first reading. This means you could eventually log lots of sleep, but still have a sleep score of 62 Fair, based on whatever hours the app first recorded. It also means that while you've clearly slept through the night, the shorter periods means you won't get proper sleep details either. Another issue is plain inaccuracy even when all hours are accounted for ie when hours awake plus hours asleep don't even vaguely add up to hours in bed. I joke with family that I must be astro-travelling! I've tried everything to fix this so good luck!
