## What is ShiftSleep?

ShiftSleep is the sleep optimization companion built for shift workers. Early, late, night, rotating — your body craves consistency, but your schedule won't allow it. ShiftSleep does the next best thing: it gives you the smartest sleep window for every single shift you work.

WHY SHIFT WORKERS LOVE IT
Most sleep apps assume you sleep at night. ShiftSleep assumes nothing. Tell it your shift pattern and chronotype, and it computes the optimal sleep window, wind-down time, caffeine deadline, and light exposure plan for each day — based on real circadian science.

KEY FEATURES
• Shift patterns — handle Early/Late/Night/Off in any rotation
• Personalized sleep window per shift, per day
• Wind-down, caffeine cutoff, and light exposure reminders
• Sleep log with quality 1-5, notes, and nap flag
• Sleep debt tracking — see how much rest you actually owe yourself
• Weekly summary with shift-vs-sleep correlation
• Smart Alarm tied to your shift schedule
• Health import — pull in last 7 days of sleep data
• Beautiful Swift Charts visualizations
• 100% on-device, no cloud sync, no tracking

PERFECT FOR
• Nurses, paramedics, ER staff
• Police, firefighters, security
• Pilots, cabin crew, transport
• Factory, manufacturing, oil rig workers
• Anyone with a non-9-to-5 schedule
