Import your roster once and the whole month is laid out in colour: duty days, days off, standby, simulator and ground training, each instantly recognisable. Tap any day for the detail behind it. BUILT FOR CREW • Every time in the local time of the airport it belongs to, with the zone and UTC offset shown, so there is never any doubt which clock you are reading • Block time worked out for every sector, and totalled for the month • Report time exactly as your roster prints it — never estimated • Layovers grouped into one card with the ground time between sectors • Day turns shown as day turns, not layovers • Tap any time to switch the whole app between local and UTC YOUR ROSTER STAYS YOURS • Everything is stored on your phone and survives app updates • The original roster page is saved under Original, so you can always check the app's times against the source • Your airline password is never seen, stored or transmitted by RosterView — you sign in on your airline's own page CREW • See which colleagues are on RosterView and compare days off side by side • Find the days you are both free — useful for swaps • Choose who can see your roster: everyone, only crew you accept, or nobody. Private means it never leaves your phone.
