Nothing is downloaded to your phone - When someone reviews one of your rest-hour days, you get told - and tapping the notification takes you straight to that day - Heads of Department and countersigners get a card saying who needs their comment, with a button that goes straight to the sheet - My devices shows one entry per phone, and signing out removes it - Switching vessel is now on the Menu, between Signature and My devices ### 1.9.2 — 2026-08-26 A new icon, and a menu that gets you anywhere on board. - The app has a new icon: the M from our own name, white on coral - Tap the vessel name to open the menu. Everything the app can do is in one place, and switching vessel has moved to Menu > Account > Vessels - Home keeps your three most-used actions in reach: All Hands, Report and Training. The centre button holds the rest, and you choose what goes there - Documents now reads like Checklists: one card per section instead of a wall of tiles - Your muster role on Home opens the duties that go with it - Signing a policy survives locking your phone, and works with no signal - it syncs when you are back in range - Every icon in the app now shares one shape and weight ### 1.9.1 — 2026-08-26 Small changes to the backend when applying bulk hours of rest offline. ### 1.9 — 2026-08-05 Your abandon ship station card now shows the whole crew posted with you: each person's duty, who leads, the equipment and the procedures. Watch handover and round notes become shared threads with faces, so the next watch knows who saw what and when. Hours of Rest shows its working: open a card for every period counted, with the regulation text. Day comments are a thread with your HoD. Plus clearer text and fixes. ### 1.8.8 — 2026-08-03 Checklists you work through together. Open the same round as your crewmates and watch answers land live, each one wearing the face of who gave it. Notes are now a thread, so nobody's words get overwritten, and you can add photos with the in-app camera straight from the question. Muster alerts now break through Silent and Do Not Disturb. Drills stay ordinary notifications. Training reads better and answers fairer. Cards play in short beats, a real Back button lets you re-read without re-answering, results are readable at arm's length, and single-answer quizzes let you change your mind before checking. A nudge from the bridge: If a recap is waiting on you, you can be sent a notification from and admin. It arrives as a card, and if now's not the time it waits in your bell until it's done. ## Related topics [abandon ship](https://appshunter.io/ios/topics/abandon-ship) --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
