Ratings & Reviews
— Missed a morning? Any night since you started can now be marked or corrected later from History, and the calendar shows what each night was.
— Charts draw your real nights from the very first one: no more waiting screens, five charts open after your first morning.
— New chart: sleep stages night by night — deep, REM, light and awake, with what the evening cost each one.
— Sleep hours is now plan against fact: what tonight promised, what you got, and the nights that kept the plan.
— Patterns arrive after a week: regularity, the weekend shift, where your debt is heading — one sentence each, with the size inside it.
— Coffee timing became an editor: drag a cup, add or remove one, and tonight's plan re-prices on the spot.
— Sleep debt is priced more fairly: a night an hour short now owes half an hour, so an ordinary week no longer reads like a crisis.
— Energy now shows tomorrow, the day tonight's plan is for; today's shape sits one swipe away.
— Rhythm draws your bed and wake times as a fan, with your typical night marked once five nights are in.
— The reminder tells you what the next night unlocks, in the same words as the charts.
