Watches
Stand it, log it.
A watch is two taps. Start time, end time, role. Edit later if the day overran — nothing's locked the moment you save.

What it does
Three jobs, done properly.
Logbook stays out of the way on watch and earns its keep at appraisal time. No habit-loop, no streaks, no nagging.
Voyages
Port to port.
Vessel, GT/kW, dates, distance. Filter the way an officer actually remembers a career: by ship, by season, by rotation.
Certificates
Tickets that ping you first.
Every ticket in one place with expiry reminders that fire well before the deadline catches you. Metadata only — no scans, no leaks.
A look around
Four screens, that's the app.
Logbook is one tab per job. Home, Logbook, Career, Certificates. No menus to dig through, nothing to subscribe to.
Inside the apps
Quiet interfaces, working screens.
Calm purple for Study, warm chart-paper for Logbook. Each app keeps its own register and reads like an instrument — not a dashboard.

Built where it's used
Bridgedeck started because nothing on the App Store understood a watchkeeper's day. Logbooks were forms. Study apps were quiz decks. So we built the tools we wished we'd had on watch — and shipped them.

FAQ
Things people actually ask.
What counts as a sea day?
Any 24-hour period in which you stood a watch. Logbook counts the way the MCA counts — if you signed off a watch that day, it's a sea day.
What happens after 100 days if I don't upgrade?
Everything you've logged stays in the app and stays exportable. New watches stop saving until you upgrade or export. We don't hold your career hostage.
Is my data really off the cloud?
Until you flip sync on, yes — the database lives in your phone's app sandbox. Sync, when enabled, uses our Supabase instance in Frankfurt with row-level security and no third-party analytics.
Does the PDF pass a flag-state audit?
It mirrors the MCA / PYA Sea Service Testimonial layout for the fields v1 captures. Master sign-off lives in v2. For now, treat the PDF as evidence, not as a substitute for the signed paper.
The bridge between
your sea time and your ticket.
Study is live on the App Store. Logbook hits TestFlight this summer. Open either to get started.
