Why SleepKit Doesn't Show You a Sleep Score

Many sleep and recovery apps lead with a number: a score out of 100, a readiness percentage, or a label such as “Restorative” or “Poor.” SleepKit does not use one.

The problem with a single number

A blended score combines different things: how long you slept, how steady your timing was, and how settled the night felt. Someone must decide how to weight each part, and the final number hides those choices. A 62 could mean “you slept short but soundly” or “you slept plenty but restlessly.” The number alone cannot tell you which.

A nightly score can also turn sleep into a grade. You wake up, check your phone, and an algorithm tells you whether last night was good or bad. For people who already feel anxious about sleep, that can be one more thing to worry about.

What three rings give you instead

SleepKit shows duration, consistency, and quality as three separate rings, every time, and never averages them:

• duration - how much you slept, against the goal you set
• consistency - how close your bed and wake times were to your own recent rhythm
• quality - led by sleep continuity, with stages and recovery signals adding context

When something changes, you can see what changed. Maybe duration is fine but consistency dropped after a late night, or quality dipped while duration and consistency held steady. That gives you more to work with than “your score is 68.”

Compared against yourself, not a curve

Each ring is measured against your rolling 28-night baseline, not a one-size-fits-all standard. Before 14 valid nights, SleepKit uses your planned schedule and general healthy reference bands. Your pattern remains the reference point.

What we deliberately left out

The app has no labels such as “Solid” or “Restorative,” and no sleep score in Trends or Friends. Friends can see your latest three ring values and duration until the end of your sleep day, but not your history.

SleepKit keeps the details visible without turning a night of sleep into a report card.
