DP Log
DP Log is an optional module for Dynamic Positioning officers. Enable it in Settings β Modules β DP Log.
What it does
Tracks DP hours on vessels across 30-minute time slots (48 slots per day). Records are grouped by day. Total Active and Passive DP hours are calculated automatically.
Setup
- Enable DP Log in Settings β Modules.
- Restart the app β the DP tab appears in the bottom navigation.
- On the DP screen, enter vessel name, IMO, GRT, DP class, contract dates.
- For each day, tap time slots to mark them as Active (blue) or Passive (grey).
- Export the month as a PDF DP Time record.
MPC β Midnight Position Check
MPC (Midnight Position Check) is an optional module for seafarers working in UK waters. It automatically records your vessel's GPS coordinates at midnight London time and checks whether you are inside or outside the 12 nautical mile UK territorial waters zone.
Why it matters
UK seafarers may need to prove they were outside territorial waters at midnight on each day to avoid NI contribution liability. MPC automates this daily record.
Enabling auto-record
- Enable MPC in Settings β Modules.
- Restart the app β the MPC tab appears.
- On the MPC screen, turn on the "Auto-record" toggle.
- Grant "Always" (background) location permission when prompted.
- The app will automatically record your midnight position every night.
How auto-record works
A background location task runs every ~10 minutes. At 23:55β00:05 London time it captures the most recent GPS fix, checks the UK 12 nm zone polygon, and saves a record with status OUTSIDE or INSIDE. A silent notification confirms the save.
Manual records
Tap "+ Add Record" to enter a position manually. Use the GPS button to fill coordinates automatically. Tap a record to edit it.
PDF export
Select a month tab and tap "Export PDF" to generate a Midnight Position Check report with your name, rank, vessel name and the full month's records.
Backup & Restore
All data is stored locally on your device. Use the backup feature to export and restore your data, or to transfer it to a new device.
Exporting a backup
- Go to Settings β Data Management β Export Backup.
- The app creates a
.sdmfile with all your data. - Share it to iCloud Drive, Google Drive, email, or any storage app.
- The file name includes a timestamp:
seafarer_backup_YYYY-MM-DD.sdm
Restoring a backup
- Go to Settings β Data Management β Import Backup.
- Select the
.sdmfile from your storage. - All existing data will be replaced with the backup contents.
- A success message confirms the restore.
Old .json backups
Backups from older versions use .json format. SDM can still import them. After importing a .json backup, export a new .sdm backup for future use.
Clear all data
Settings β Data Management β Clear All Data permanently deletes everything from the device. This cannot be undone. Export a backup first.
SDM Reader (Web)
SDM Reader is a free companion web tool that opens your .sdm backup files right in a browser β handy for reviewing a profile on a computer, or for a crewing manager to look through a seafarer's documents and sea service. It runs entirely in your browser: nothing is uploaded, and no account is needed.
Opening a profile
- In the app, export your data: Settings β Data Management β Export Backup (creates a
.sdmfile). - Open SDM Reader in any browser.
- Tap Import .sdm and select one or more backup files.
- Each seafarer appears as a row β name, position, nationality, contacts and counts of documents and sea-service entries.
- Tap a name to open the full profile: Profile, Documents, Sea Service and Education tabs.
What you can do
- View the photo and a professional summary (position, nationality, preferred vessel, day rate, availability)
- Tap the contact buttons to open Email, Call, WhatsApp or Telegram directly
- Browse the full Documents and Sea Service tables, search by name/position/nationality and sort columns
- Load several backups at once to compare profiles side by side
Attaching scans
You can also load the document scans that belong to a profile so they appear next to each document row:
- In the app, open Scans, select the files and tap Archive & Send to create a ZIP of PDFs.
- Save that ZIP, then in SDM Reader tap Import scans and select the ZIP (or the individual PDFs).
- Each PDF is matched to its document automatically by name and date β a π View link appears in that document's row and opens the scan.
- Camera scans and any file that can't be matched are listed separately under βUnmatched scansβ.
.sdm backup contains your personal data and is not encrypted. Only open it on a device you trust, and don't share the file publicly.Unlimited
