The Watchkeeper App builds and runs your boat's watch bill — offline, private, and made for the way crews actually stand watch.
Whether you're crossing an ocean or running a delivery, Watchkeeper turns your crew list into a fair, legal, easy-to-read rotation in minutes — then keeps it running through the whole passage.
BUILD THE ROTATION YOUR WAY
• Proven patterns — circadian (Swedish/Navy), traditional four-on/eight-off, and more — or build your own from scratch.
• Two-, three-, four-crew and larger; individuals or teams.
• Drag to reshape any watch; edit a single day or the whole cycle.
STAND THE WATCH
• See who's on now and who's next, in boat time.
• Alarms before every watch — Time-Sensitive, so they break through Focus.
• Heavy-weather mode shortens watches with one tap and eases back off when it passes.
REST THAT HOLDS UP
• Automatic STCW rest checks flag a rotation that won't give the crew legal rest.
SHARE IT, PRINT IT
• Send a shipmate the whole voyage by QR, AirDrop, message, or email — they scan and it's loaded.
• Print a one-page watch bill for the bulkhead, with a scan-to-load code.
ON THE WATER
• Set the ship's clock to your longitude, mark a man-overboard reference and steer back to it, and keep a position log.
PRIVATE BY DESIGN
Watchkeeper has no account and no servers. Your schedules, vessel, and crew never leave your device — we can't see them. Sharing is peer-to-peer; we never see who you send to.
For sailors, by sailors.
