When reporting a problem, it helps to include your iPhone model, iOS version, a screenshot, and a short description of what happened.

Getting started

  1. Answer three questions: how much sleep you want, whether you're an early bird or a night owl, and your one-way commute.
  2. Pick a shift type (Day, Evening, Night or Custom) and tap the days you work over the next fortnight. Your plan appears immediately on Today.
  3. For repeating patterns, open Schedule → + → Rotation template and choose 2-2-3 (Pitman / Panama), DuPont, Continental, 3-on/4-off, 4-on/4-off, 2 days / 2 nights / 4 off, weekly rotation, or Mon–Fri. Set when the cycle starts and how many weeks to add.

Frequently Asked Questions

How does the app decide when I should sleep?

It applies widely agreed shift-work sleep-hygiene guidance to your real roster. After a night shift, sleep as soon as you get home and take a 90-minute nap in the late afternoon before the next night. Before a day or evening shift, your main sleep is anchored to end when you need to get up (commute plus getting ready). After your last night shift, take a short recovery sleep of up to four hours, then go to bed early that evening. Before your first night shift, sleep in and nap beforehand. On days off, bedtime follows your chronotype. The caffeine cutoff defaults to six hours before planned sleep. Every input can be adjusted in Settings.

Is this medical advice?

No. RosterRhythm offers general guidance for shift workers. If you have persistent sleep problems, please talk to a clinician.

What do the light reminders mean?

Bright light early in a night shift keeps you alert; wearing sunglasses on the morning commute home stops daylight telling your brain it's time to be awake; and 20 minutes of daylight after a night-time sleep anchors your body clock.

What is a "short turnaround"?

When the gap between two shifts is too small to fit your full sleep target, the plan fits in as much sleep as it can and marks the block with a warning. Protect that block and take the nap if one is planned.

Can I track more than one job, overtime or on-call?

Yes. Add jobs in Settings → Jobs and give each a colour. Mark a shift as Overtime or On call when you add it. On-call time is not treated as work: the plan tells you to sleep normally and keep the phone by the bed.
