Shift Calendar – Backshift

Your shift pattern, set up once. Your whole month, clear at a glance.

Backshift is a shift calendar for people whose week doesn't start on Monday: nurses, doctors, police officers, firefighters, factory and warehouse crews, security officers, care workers and anyone on a rotating schedule.

BUILD YOUR ROTATION ONCE
Two days, two nights, four off? Build it step by step and your calendar fills itself: this month, next month, every month. Start from a ready pattern (2 days · 2 nights · 4 off, 24 on · 48 off, three shifts 3×8, 5 on · 2 off) or build your own with any shift types, hours and unpaid breaks, like a 14 on · 7 off oilfield hitch. Swapped a shift, took PTO or called in sick? Change that one day without touching the rest, and add a note if you like.

YOUR MONTH IN COLOR
Every shift type gets its own color band across the month. Spot three nights in a row or four days off before anyone asks "are you free on the 14th?" Prefer a list, light mode or larger text? It's all there.

HOURS AND ESTIMATED PAY
Enter your hourly rate and Backshift shows the month's hours, overtime and estimated earnings on one clean page. Night, overtime, Sunday and holiday premiums follow the percentages you set. When a shift ends you get one question; skip it and the shift counts as planned. It's a personal estimate of your paycheck, not a pay stub or payroll.

CHECK YOUR PAY STUB
Paid monthly? Choose the month and enter the gross amounts from your pay stub. Backshift compares them with the shifts you worked and shows, line by line, where base pay, a premium or the gross total doesn't match, with the math behind each line. Only gross amounts are compared; net pay, taxes and deductions aren't included. Part of Backshift Pro.

WITHOUT OPENING THE APP
During a shift, open the app once and the time left counts live on your Lock Screen and in the Dynamic Island, with your estimated pay too on Pro. Widgets show your month and your next shift. On Apple Watch, check your week and see your next shift right on your watch face. Get a reminder before every shift, at the time you choose.

SHIFTS FOR TWO
Share your calendar with one person and see both rotations side by side. The days you're both off are highlighted. Your pay and notes are never shared.

NIGHT SHIFT GUIDE
Short articles on daytime sleep, caffeine timing and winding down, each with its real sources listed. General wellness information, not medical advice.

EXPORT
A monthly PDF report, plus a calendar file (.ics) for any calendar app.

MADE FOR 3 AM
Dark mode first, high-contrast colors, numbers that line up. Your data stays on your device and syncs with your own iCloud. Back up and restore anytime. Available in 36 languages.

FREE AND PRO
The calendar, the rotation builder, the live timer, widgets and Apple Watch are free, forever. Backshift Pro adds your weekly and monthly pay with past months and comparisons, the pay stub check, export, unlimited shift types, calendar sharing and the night shift guide. The yearly plan starts with a 1-week free trial. If Pro ends, your calendar and records stay. Choose monthly, yearly or a one-time lifetime purchase.
