Crew Prime is a modern aviation logbook and roster companion built for pilots and crew members who want a clear view of their schedule, duties, flight time, income and shared roster activity. Import company roster files, personal roster files or supported calendar feeds, then review your duties in a clean calendar, logbook and map experience. Crew Prime helps organize flights, sectors, duty types, crew details, aircraft information, airport routes and income calculations in one place. Key features: • Import PDF, CSV and ICS roster files • Review monthly and weekly roster summaries • Track flight time, block time, duty time and route sectors • View routes and airports on an interactive map • Estimate planned and finalized income from your own rules • Add roster corrections when company files are incomplete • Share selected roster details with trusted connections • Back up and restore data with cloud sync • Export useful reports for personal records Crew Prime organizes roster and logbook data from sources selected by the user, such as company roster files, calendar feeds, personal files or supported portal exports. The level of detail shown in the app depends on the data available in those sources. Crew Prime is independent and is not affiliated with any airline, employer, crew portal, payroll system, flight operations system or aviation authority. For official roster changes, duty assignments, payroll, compliance and operational decisions, users should always rely on their airline, employer or official company systems. Premium unlocks higher usage limits, frequent roster imports, advanced data operations and cloud-first workflows for pilots who rely on their logbook every month.
