CrewRest: Flight Crew Calculator Calculate shift rotations in Zulu time instantly Stop doing mental math at 35,000 feet. Calculate fair, exact rest periods for your team in seconds. **CrewRest** is designed by and for long-haul flight crews to take the hassle out of calculating rest periods. Built to handle the realities of aviation, CrewRest quickly generates accurate shift rotations using Zulu time so you can get back to what matters. Whether it’s a standard rotation with uniform gaps or a complex shift with mid-flight services, CrewRest handles the math flawlessly—ensuring the last person's break is never cut short. Key Features *Two Calculation Modes** - **Easy Mode:** Perfect for standard flights. Input a single changeover duration, and the app distributes it evenly between all breaks. - **Advanced Mode:** Handling a mid-flight service? Set individual changeover times for each gap (e.g., 5 mins for the first gap, 25 mins for the second). **Fair Time Distribution** If the total rest time doesn't divide perfectly, CrewRest automatically distributes the “remainder” minutes to the *earliest* periods. This guarantees the final crew member never ends up with a shorter shift. **Smart Zulu Time Parsing** Enter times however you prefer. The app accepts `HH:MM` (12:30), `HHMM` (1230), or `HMM` (130). CrewRest automatically handles midnight rollovers for flights that cross over into the next day. **Organization & Alerts** - Tap the table to assign names to specific rest slots. - Receive vibration and notification alerts right when a rest period ends to ensure smooth changeovers. --- Why Crews Love It "Takes the guesswork and scratchpad math completely out of the equation.
