RosteK is a roster app built for flight crew. It brings cockpit and cabin crew rosters onto one screen, builds your alarms, fills your logbook automatically and keeps your flight-duty limits in view. Your whole roster at a glance A colour-coded monthly calendar: flights, layovers, standby, training, leave. Tap a day for report and release times, duty time, aircraft, airports and crew on one screen. Your roster is stored on your phone and opens offline. Alarms built from your flights Wake-up, getting ready, crew car or taxi, hotel pickup — the alarm chain is calculated from your flight. Tune every interval to the minute and send it to the Clock app with one tap. On a layover, times follow your hotel departure. Your logbook fills itself Flight, duty, leg and layover totals, year by year and month by month. Record block times, approach type and landings after each flight on one screen. Your limits, always in view 7, 14 and 28-day duty and flight times plus yearly limits, with each flight's share listed. You choose who sees what Share your roster person by person: hidden, busy/free only, or full detail. Sharing starts with mutual approval, and you can change or stop it at any time. Small things that help Your taxi message is ready with date, time and address — send it via WhatsApp or Telegram in one tap. Pre-flight and post-flight notes only you can see. METAR and TAF for your airports, a map of your layovers, your most-flown routes. Privacy comes first Your roster months, crew list, notes and settings are encrypted on your phone with a key derived from your 12 words; the server cannot open them. The key is yours alone. The basics your account needs to work (name, role, username, friend list, sharing choices) are stored so that only you can access them. Sign in with your username and 12 words, or with Face ID / passkey. RosteK is an independent app and is not affiliated with any airline.
