Shift Science: Fatigue Monitor

Shift work wrecks sleep, and the tiredness builds up in ways you can't feel. Shift Science reads the work calendar you already keep and predicts your alertness across the next two weeks, so you can see the rough patches coming and plan around them. Point it at your schedule and it works out when you'll realistically be able to sleep around your shifts, then models how alert you're likely to be, hour by hour. WHAT IT DOES • Predicts your alertness (0–100) for the next 14 days on a scrollable timeline • Shows your current level at a glance, in plain English • Warns you before a predicted low — and before a drive home that looks unsafe • Evidence-based tips: when to nap, when to use (and stop) caffeine, how to use light on nights, and how to recover after a block of nights • Tracks the sleep debt and body-clock drift that build up across a run of shifts BUILT ON REAL SCIENCE Shift Science…
