About Boat GPS Speed & Course
Boat GPS Speed & Course is a simple GPS speedometer and course display for boats.
The app shows your current speed in knots and your Course Over Ground (COG) based on GPS movement. It does not use the phone’s magnetic compass, so the direction shown is the direction of travel, not the direction the phone is facing.
Features:
- GPS speed in knots
- Course Over Ground (COG)
- Cardinal direction display
- Day and night mode
- Large, clean marine-style gauge
- No map, no route tracking, no login
Boat GPS Speed & Course does not require an internet connection for its core GPS speed and course functions. Internet may only be used for displaying ads.
The app does not store routes, does not save location history, and does not send your GPS location to our servers. Location is used only while the app is open to calculate speed and course.
