Your shifts in one calendar. Your sleep planned around them. Photograph your roster, share it with home, and let your alarms move when your shift does.
Vessa is a shift work calendar that also plans your sleep.
Enter your shifts, or photograph your roster and let Vessa read it, and see your month at a glance. Then Vessa turns the shifts you actually work into a 72-hour sleep and caffeine plan, and re-plans it when a shift moves. Night shifts, rotating blocks, short turnarounds and last-minute swaps: the calendar keeps up, and so does the plan.
FREE
• A shift calendar: enter shifts by hand, as many as you like, or start from templates for 3×12, fixed nights, 24/48, DuPont and other common rotations
• Your first roster import from a photo
• Your shifts in the iPhone Calendar: one event per shift in a "Vessa" calendar you can share from the Calendar app, with your planned sleep if you want it
• Share your next four weeks as one page, as an image or a PDF
• Home Screen and Lock Screen widgets with today's shift and your next sleep
• A note on any day: where you're working, who you're with
• A 72-hour sleep plan built from your shifts: main sleep, recovery sleep, pre-shift naps, off-day sleep, wind-down and caffeine cutoff
• Every sleep is a switch: turn naps, recovery sleep and days-off sleep on or off, or keep your days off free of reminders
• Edit any sleep for one day or for good
• The plan re-plans itself when a shift changes, and tells you three days before your schedule runs out
PREMIUM
• Roster import, every cycle: photograph your roster, tap your name, confirm what Vessa read. Nothing to type
• Alarms set by Vessa: wake-ups for every sleep in your plan go on your iPhone as real alarms, and move when your shift moves
• Sleep ledger: what you planned next to what you slept, read from Apple Health, day by day and by sleep type. Needs an Apple Watch or a sleep tracker that writes to Apple Health
Premium is an optional auto-renewing subscription, monthly or annual; the annual plan starts with a 14-day free trial. Cancel any time in Settings → your name → Subscriptions.
PRIVACY
Roster photos are read on your device and never uploaded. Apple Health data is read on your device and never leaves it. Your shifts, day notes and plan settings sync to your account so they survive a new phone. If you turn on Calendar, your shifts are written to a calendar on your iPhone, and Vessa reads only that calendar.
Vessa is designed for nurses first, and works for EMS, firefighters, factory workers, security, drivers, hospitality and anyone on demanding shifts.
Vessa is a planning and self-care tool. It does not provide medical advice, diagnosis or treatment. If you have persistent sleep problems, please consult a qualified healthcare professional.

New in 1.3.0
• Vessa now speaks Spanish, French, Portuguese and Turkish, and follows the language you choose for it in iPhone Settings.
• A new look: a full-screen month calendar and a clearer Plan.
• A new Share tab: keep your shifts in a partner's Calendar, or send your month as an image or a PDF.
• In your iPhone Calendar, each shift and sleep window now sits on the day it starts, with its times in the title.
• Got an offer code? Redeem it in Settings.
• With VoiceOver on, the two-finger scrub closes a sheet.
Plus fixes: reinstalling Vessa no longer makes a second "Vessa" calendar.
