Night shift wrecked your sleep? DrowZe turns your roster into a sleep plan that moves when your shifts do ā built for nurses, paramedics, and anyone on nights or rotating schedules. Most sleep apps assume you sleep at night. DrowZe starts from your shifts: when you finish, when you're back on, how long your commute is, and whether you're an early bird or a night owl. Then it tells you exactly when to sleep, nap, stop caffeine, and see light.
