CrewRest+ is an application designed for flight crew members, both cockpit and cabin crew, operating long-haul flights. It is a rest scheduling calculator (and duty-service scheduling for cabin crew) that provides a simple and efficient flight timeline, displaying the duration, start time, and end time of each rest and/or duty-service period based on the entered data. Several scenarios can be selected, such as splitting the total duration into 3 equal rest periods, or 4, or even 6. Some airline-specific scenarios have been requested by pilots and are also available in the scenario catalog: Cathay, Virgin, Swiss, and Air New Zealand options. Breaks between rest periods are defined by the user. For cabin crew, breaks before rest periods and before duty periods can be set differently. Once the timeline is displayed, durations can be adjusted according to the actual flight context (except for the airline-specific scenarios mentioned above). The timeline can also be shared as a PNG image with other crew members. The application is available on both iPhone and iPad. --- Note : The app includes a free trial allowing up to 5 timeline calculations, with full access to all features. After these 5 calculations have been used, continued access to the app and its features requires an auto-renewable annual subscription priced at $6.99 per year. Payment will be charged to your Apple ID account at confirmation of purchase. The subscription automatically renews unless it is canceled at least 24 hours before the end of the current billing period. Your account will be charged for renewal within 24 hours prior to the end of the current period. You can manage and cancel your subscription at any time in your App Store account settings under “Subscriptions“. This application uses Apple's standard Terms of Use (EULA) : https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
