The framework
One number for surviving your rota
Fitness apps score your sleep as if you work 9-to-5. The Sleyp Score is built for the rest of us, a 0–100 measure of how well you're actually coping with non-standard hours, built from four practical sub-scores you can influence this week.
Rota Adaptation Score
How well your body clock has settled into your current pattern.
Built from: Shift pattern, rotation speed, chronotype match, consistency of sleep timing.
Noise Impact Score
How much your daytime sound environment is degrading your sleep.
Built from: Noise source ratings, masking defences in use, physical room defences.
Circadian Recovery Score
How effectively you transition between shift blocks and days off.
Built from: Flip-flop discipline, light exposure timing, anchor sleep usage, meal timing.
Accumulated Sleep Debt Score
The gap between the sleep you need and the sleep you're banking.
Built from: Logged sleep vs personal requirement across your rolling shift block.
How the overall score works
Your overall Sleyp Score is a weighted blend of the four sub-scores, with Accumulated Sleep Debt carrying the heaviest weight, because debt is the component that turns into a safety problem fastest. Quick inputs across the tools and trackers keep each sub-score current; nothing requires a wearable.
Quick inputs from the tools and trackers feed your score, and your entries stay in this browser on this device.
Frequently asked questions
What is the Sleyp Score?
The Sleyp Score is a single 0–100 number that tells a shift worker how well they're coping with their rota. It combines four sub-scores: Rota Adaptation, Noise Impact, Circadian Recovery and Accumulated Sleep Debt, each built from quick practical inputs rather than wearables or lab data.
How is the Sleyp Score different from a sleep tracker score?
Wearable scores assume a normal night sleeper and judge you against a 10pm–6am world. The Sleyp Score is built for non-standard schedules: it knows a 6-hour day-sleep after a night shift is a different achievement from a 6-hour night sleep, and scores you against your rota's reality.
How do I improve my Sleyp Score?
Each sub-score maps to a tool: fix Noise Impact with the Noise Calibration Tool and a tuned session; fix Circadian Recovery with the Rota Flip-Flop Calculator; fix Sleep Debt with the logger and recovery naps; and improve Rota Adaptation by matching tactics to your chronotype.
