Bloodwork tells you where you stand. Sleep tells you how today went, how this week is trending, and whether your protocol is actually working. Every morning, the engine reads last night's data and writes you a briefing in plain English.
The moment last night's data lands — manual log, WHOOP, Oura, or imported file — the engine reads it against your last 30 days. It accounts for your alcohol, caffeine, stress, cycle phase, and active medications. Then it writes you a verdict, the drivers, the headwinds, and the call for today.
HRV rebounded to 64ms (+18% vs baseline). Deep sleep at 94 min — best this week. Cortisol pattern looks well-recovered.
Green for hard training. Push the lift. Caffeine cutoff 12pm.
Most apps give you a single sleep score. We break it into the five things that actually matter, so when something dips you know which lever to pull.
HRV and resting heart rate compared to your personal 30-day baseline. Catches when you're under-recovered before you feel it.
Deep and REM minutes vs targets. The two stages that do the actual restorative work.
Total sleep against your personal need — not the 8-hour myth. Some bodies need more, some less.
Bedtime and waketime variance over the last week. The most underrated lever in all of sleep.
Rolling 14-day cumulative deficit. Tracks the slow drift before it becomes a crisis.
Weighted roll-up of all five, plus 7-day and 30-day rolling trajectories.
One night is noise. A week is a signal. A month is a trend. A quarter against your bloodwork is a story. The Sleep Engine writes all four.
Morning briefing the moment data lands.
Sunday rollup: best night, worst night, what drove the swings.
Score trajectory + cycle-phase and lifestyle correlations.
Bloodwork-aware: ferritin up, sleep up. Magnesium dose, deep sleep up.
