RosterRhythm: Shift Sleep Plan is a sleep planner for iPhone built for people whose sleep doesn't happen at night: nurses, doctors, paramedics, pilots and cabin crew, police and firefighters, security, drivers, and factory and warehouse teams.

Standard sleep apps assume a fixed bedtime. RosterRhythm starts from the one thing that actually rules your sleep: your shift schedule.

Enter your shifts, get a plan

Tap out this fortnight's days and nights in seconds, or generate weeks at a time from the rotation your workplace uses: 2-2-3 (Pitman / Panama), DuPont, Continental, 3-on/4-off, 4-on/4-off, 2 days / 2 nights / 4 off, weekly rotation, Mon–Fri. Overtime, on-call and a second job are all understood.

Science-informed, plain-spoken

For every shift, RosterRhythm works out:

• your main sleep window and when to wake
• the last time caffeine is a good idea
• when to wind down
• when a strategic nap will carry you through a night
• when to seek or avoid light

Switching from nights to days? It plans the recovery sleep and the early bedtime that gets you back in step.

One glance, every day

Today shows the next thing to do, the next 24 hours as a timeline, and the week ahead. Optional reminders fire at the right moment: wind down, last coffee, nap, get up.
