Pick a proven pattern for crews from 2 to 10, as individuals or as teams. Circadian, Swedish, Navy and US Merchant Marine schedules, traditional four‑on eight‑off. All completely customizable, or build your own from scratch. Every rotation is checked against STCW rest minima, so you know it’s legal before you slip lines.
On‑Watch shows the current hand and the next, in boat time, with a haptic nudge at every change. Watch alarms are Time‑Sensitive, so they break through Focus and Do Not Disturb when it matters.
Heavy‑weather mode shortens the watches the moment it turns nasty and eases back to normal when the front passes — the log stays honest throughout. Night mode goes fully red to protect your night vision on deck.
Drop a man‑overboard reference with one touch from the ‘On Watch’ screen, and follow the bearing and range back to it. Set the ship’s clock from your longitude by GPS, and keep a running position log — all on‑device, no signal needed. Saved positions are only for use as a backup aid, and never as your primary rescue or navigation device.
No account. No servers. No trackers. No ads. Your schedules, vessel, and crew are yours. We have no way to see them.
