SeaPilotApp

About this app

SeaPilotApp is a practical marine companion app for Android. It displays AIS / NMEA 0183 data in real time and provides an onboard‑friendly interface for situational awareness, manoeuvring and pilotage support.
Built for real use, SeaPilotApp focuses on fast readability, simple connection workflows, and useful tools for close‑quarters operations.

What you can do in the current build:
Connect to AIS / NMEA sources
Wi‑Fi (TCP)
Wi‑Fi (UDP)
Bluetooth
Easy setup with IP/Port (Wi‑Fi) and quick connect / disconnect.

Live NMEA/AIS stream & log:
View raw incoming NMEA/AIS sentences in real time
Built‑in AIS Data Log for monitoring and testing
Useful for validating data streams from AIS receivers, GNSS devices, bridge systems and log exports.

Sea Map (osmdroid):
Online layers (internet required; depends on provider availability)
OpenSeaMap overlays (seamarks / marine overlays) when available
Map orientation modes (North Up / Course Up / Free rotation)

Offline maps (no internet required):
Import and use offline map files stored on your device:
MBTiles (.mbtiles) — raster tile packages (PNG/JPEG)
Mapsforge (.map) — vector offline maps
Offline maps are used locally on the device and must be downloaded by the user separately.

Route Planning (GPX / RTZ):
Load voyage plans, edit waypoint list, save/unload routes
XTE corridors (cross‑track error boundaries) for route monitoring

Dynamic vessel data screens:
Dedicated screens for key real‑time values such as SOG, COG, HDG, ROT (as available from your AIS/NMEA source).

Docking / manoeuvring helper screen:
A VRM‑style docking screen designed to be readable during close‑quarters operations.
Optional display of nearby vessels/targets (when AIS targets are available)

GPS screen:
A separate screen showing phone GPS data (position, SOG/COG, local time), independent from AIS input (when available).

Test Mode (no hardware required):
Replay a text file with NMEA/AIS sentences and simulate a live stream.

Alarms (safety support):
Collision Risk (CPA/TCPA)
Anchor Drag (Anchor Watch)
GPS Loss
Route Deviation
Arrival to Waypoint

Privacy / Important notes:
SeaPilotApp works locally: data is not sent to any server.
SeaPilotApp is a supporting tool and is not a certified navigation system (not ECDIS). Always cross‑check with official charts and onboard equipment.
Some features require compatible AIS/NMEA equipment and local connectivity.

What’s new

Added support for echo sounder depth data and speed log data from supported NMEA sources.
Added motion vectors to the Docking Screen for clearer vessel movement awareness.
Added Google Play in-app update support.
General bug fixes, performance improvements, and internal code cleanup.
