SeaCal

Track your sea time, monitor certificate expiry, and log in/out-of-country days for tax — all in one place, fully offline and private.

SeaCal is the all-in-one companion for professional seafarers — track your sea time, manage certificate expiry, and log your in/out-of-country days, all from your phone.

Sea Time Tracking Log every voyage by ship, rank, and Certificate of Competency (COC). SeaCal automatically calculates your progress toward PDR (Prescribed Days of Rest) requirements and shows exactly how many qualifying days you have per rank and COC — no more spreadsheets.

Certificate Management Keep every STCW and other certificate in one place. Attach photos or scanned PDFs of each certificate, and get advance alerts before anything expires — so you're never caught out at a port state control inspection or a new contract's onboarding check.

Day Tracking for Tax Log in-country and out-of-country days to keep an accurate record for tax residency calculations (e.g. Seafarers' Earnings Deduction). Two configurable rolling-year trackers keep a running tally so you always know where you stand.

Built for privacy All your data stays on your device. There's no account to create, no cloud database, and nothing is uploaded except a small, one-way configuration check. Your voyages, certificates, and day logs are yours alone, you can save this to your device, email it or put on a usb as a backup.

Whether you're a cadet building your first sea time or a senior officer juggling multiple COCs, SeaCal keeps your career paperwork organised and your PDR eligibility one tap away.
