Map of displays / quick reference guide

Mariner for Wear OS is designed for easy switching between data displays, and for each display to be legible at a glance while sailing. Swipe up and down to navigate between each section. Tap ›› on any statistic display (time elapsed, distance, average and top speeds) to cycle between them. Using your watch’s crown or rotating bezel is the fastest way to move between displays.

Refer to this handy Quick Reference Guide to learn where each of the displays are:

Starting the app / recording journeys

GPS source selection, Mariner GPS Dashboard for Wear OS

When you start the app for the first time you will be prompted to select your preferred connectivity mode for the app:

1. ⌚️ Standalone mode: internal GPS, hybrid GPS, and NMEA

Internal GPS primarily uses the GPS capability built into your smartwatch. GPS hardware in watches may be subject to more latency than phones and tablets due to their smaller size. By default, the app uses a ‘hybrid mode’ – combining GPS signals from both your watch and paired handheld for more accurate and timely location updates. Alternatively you can choose to always use the watch’s internal GPS alone by switching off hybrid mode in the settings menu.

💡 You don’t have to have the app installed on your handheld device to use its signals in hybrid mode.

ℹ️ Journey recording and storage is not available in Standalone mode due to the limited memory and battery capabilities of smartwatches


2. 📱 GPS tethering mode (sync with paired handheld app)

In tethering mode, your recording session will be synchronised with the app on your paired smartphone. All journey statistics will be mirrored from the phone, and your watch will act as a secondary display.

When you start a journey in tethering mode, your watch will attempt to start the app on your phone and begin recording your journey. On some phones, and depending on your system settings, you may have to start the app manually if the system is in sleep mode. You may need to change your power management settings allow Mariner to start up in the background.


Starting and stopping journeys

The app will start a new journey session automatically when you start the app. You can change this in settings with the ‘Automatic start’ setting. To start a journey manually, tap and hold on the screen to start the session. A single tap will prompt you to tap and hold. The ‘tap and hold’ action is a safeguard to prevent you from activating the GPS when you don’t intend to.

Wind displays – speed, direction, and angle

1. Heading & wind mode (weather from internet)

Swipe right-to-left on the speedometer display to switch to Heading & Wind mode. Your watch will pick up local weather information from the internet and display it alongside your boat speed and direction. Below the directional arrows you’ll see the heading and wind direction in degrees, and their corresponding speeds underneath.

If you are in GPS tethering mode and you have SailTimer as your wind source, the live wind direction data streamed from your phone into the wind section and a bluetooth signal indicator will appear to the bottom-right of the wind direction arrow.

Internet weather data is currently sourced from OpenWeatherMap.


2. SailTimer wind angle mode

In tethering mode your bluetooth connection status will be indicated on the speedometer view with one of two colours. This indicator will appear amber while the watch waits for the first signal from the smartphone app, or if it loses connectivity during your journey session.
