Derrick
Keep your hitch straight, and your time at home in view.
iOS
An oilfield calendar for your rotation
Choose a rotation such as 14/14, 14/7, 7/7, 21/21 or 28/28, or enter your own on/off pattern. Set the first day of your hitch and see your working days and time off across the calendar, with a countdown to going home or returning to work.
Your crew and family can follow along
Share a Crew Pass as a code or QR so another Derrick user can import the schedule. The free app includes month and agenda views, Home Screen and Lock Screen widgets, day/night shifts and crew-change reminders. It works offline without an account.
Optional tools for the whole year
Derrick Pro is a one-time purchase. It adds a printable year-at-a-glance PDF, personal events alongside your rotation, and tracking for pay, per diem, days worked and overtime. Enter your own work and pay details; the app’s record does not replace your employer’s schedule or payroll.
For contract-based seafaring
If your work is based on a merchant-seafarer contract and a sign-off date, Homebound may be a closer fit. It is another Evelaina app, designed around the countdown to homecoming.
