Drowsa: Night Shift Sleep
Shift Work Sleep Planner
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Plan sleep, naps, caffeine, and light around rotating shifts. Drowsa keeps recovery guidance private and local on your iPhone.
Drowsa helps rotating shift workers plan sleep and recovery around real-world schedules. Instead of assuming a normal bedtime, Drowsa builds practical guidance around your actual rotation.
• Ready-made shift templates for nights, days, 12-hour rotations, 2-2-3 patterns, and custom schedules
• Sleep-window planning based on your shift timing and circadian rhythm
• Nap, caffeine cutoff, and light exposure guidance
• Local reminders for sleep, wake, and recovery timing
• Optional Apple Health sleep comparison when you grant Health access
• Calendar export and shareable sleep-window messages
• Privacy-first design: no account, no cloud, no tracking; your plan stays on your device
Drowsa is built for nurses, factory workers, security staff, transport drivers, emergency workers, and anyone whose sleep has to work around rotating shifts.
Drowsa is a planning and reminder tool, not medical advice. Do not rely on it as your only alarm or for safety-critical decisions.
