Apps for Viewing the Wireless Wind Data
The SailTimer Wind Instrument™ is designed to be used with a variety of apps and marine electronics. It is compatable with the industry standard NMEA 0183 for marine electronics data. We also make the data as easy as possible for 3rd-party app developers to integrate. If you have a favorite app that cannot display real-time wind data from your Wind Instrument, ask them to email and we’ll help them add the connection.
Once you have the SailTimer API™ for receiving the wireless wind data onto your iOS or Android device, use one of the apps below for displaying the wind speed and wind direction and other related navigation information such as wind angle, polar plots and optimal tacking routes…
iRegatta Pro and free iRegatta trial version on iOS. To activate, just select the wind vane icon with our unique wind cups on the splash screen when iRegatta opens. Then you’ll see wind speed and direction on the 5th panel. Nothing needs to be set up if you open Settings on your iPad/iPhone and go to iRegatta — although you could verify under WIFI NMEA that the target frequency is set to receive data every 1 second. iRegatta also lets you see your wind-related variables on the Apple Watch.
MID WiFi and MID Wifi (Free) evaluation version. Has a great wind gauge as you can see in these screenshots for iPad and iPhone. On the wind gauge (and in the map view), the size of the blue sector indicates the variation in wind direction. To connect, at the bottom of the first screen tap Set (for Settings), then set the Server Port to TCP 55554 and the IP address to 127.0.0.1. All variables including wind speed and direction are also available on the Apple Watch, as in this example.
NMEA Sail shows your most important navigation information on one easy-to-view screen. A wind gauge displays wind angle and wind speed (True and Apparent), along with other possible wireless NMEA data if available including compass heading and boat speed. Also has a unique overlay of polar curves on the wind gauge. Depth, wind or speed can be announced continuously with audio feedback.
Sail Buddy is a lightweight app that shows course, speed and wind data with a clean, simple interface on iPhone, iPad and Apple Watch. You can see your GPS track on a land map. The Sail Buddy app can also bring in NMEA depth data on TCP or UDP wifi. That is great if you use the SailTimer Air Link to send out wifi from wired NMEA devices for viewing on your iPad or iPhone.
SailRacer is a racing app with a visual starting box showing Time-To-Burn and unique graphics including lay-lines, compass, wind direction and oscillations, and heading deviation. To connect to Wind Instrument’s API, go to Settings – Authentication and create an account with in-app purchase to unlock all features from the free trial version. Then go to Settings – Datasource and select SailTimer API.
SailTimer™: our own chartplotter app. The website has background logic, instructions and FAQs. Two versions are available in iTunes: the original SailTimer™ app with most features included with the purchase price ($14US) and the SailTimer Charts Edition™ (free) with in-app purchases for optional features.
SeaNav has marine charts for numerous countries, and a unique Augmented Reality view. It lets you see True and Apparent wind in a free Pebble Watch app. The wind direction gauge has a clever design showing both wind direction and wind angle. Tap IPC in the upper-right (Instrument Panel Cluster) to open. The parent company Pocket Mariner also has some background on developing their AIS display.
AFTrack- GPS Tracking: a full chartplotter app ( or free AFTrack-Lite version) with basic laylines for sailing based on tacking angle. There is a small red wind gauge in the lower right of the map screen, which shows True wind speed & direction from the Wind Instrument based on True North. To also add a full-screen wind gauge for the Wind Instrument (Apparent wind speed & direction based on Magnetic North), get the AFTrack SailTimer Plugin at the link below. Then when using AFTrack, select Plugin in the toolbox (wrench icon) or GPS Settings. There is an overview of how to use AFTrack here, and instructions for downloading marine charts for USA, New Zealand, US Virgin Islands and Puerto Rico. The US Atlantic Coast also includes large-scale charts of Bahamas and Cuba. The charts are placed into a folder on an SD card and scanned by AFTrack or loaded as single map manually.
AFTrack SailTimer™ Plugin: if you already use the original AFTrack or with AFTrack ST, this plug-in allows you to connect to the SailTimer Wind Instrument™ and display a full-screen wind gauge as in this screenshot.
OpenCPN for Android: the longstanding open-source chartplotter for PCs is now available from the Google Play store. To display wireless wind speed and direction, connect the SailTimer API to the Wind Instrument. Then in OpenCPN go to Settings (wrench icon) – Dashboard – Preferences, then Add wind direction or wind angle (True and/or Apparent) from this menu. You can see a wind gauge for wind angle or wind direction as in this screenshot, with vector or raster charts.
SailRacer is a racing app with a visual starting box showing Time-To-Burn and unique graphics displaying lay-lines, compass, wind direction and oscillations, and heading deviation. To connect, go to Settings – Datasource and select SailTimer API. Also includes a smartwatch version for Android Wear.
SailTimer Wind Gauge™ (free): A traditional wind angle display (True & Apparent), and also wind direction on a compass (magnetic-north & true-north). Audio interfaces are becoming more useful in cars and at home with Siri, Alexa and others. This may be even more important in sailing, so this Wind Gauge app includes Audio Navigation™. Now you don’t have to squint to try to see your screen out in the bright sun; the app will just tell you the wind conditions and boat speed whenever they change by intervals you set. See (hear) it working in this 45-second YouTube demo. Put your phone/tablet away to keep it safe, and keep your hands and eyes free for sailing. Finally, the SailTimer Watch™ app is a version for smartwatches such as the Sony Smartwatch 3, which is waterproof and easy to see in direct sunlight. Tap the watch face to toggle between dark and light backgrounds, or swipe left for brightness settings.
OpenCPN on Windows, Linux or Mac OSX: There are a lot of devoted users of this free open-source chartplotter program (background here). They have been asking if there was a way to receive transmissions from the Wind Instrument on computers, and now there is. The Android version of OpenCPN (above) can receive the wind data and retransmit to the PC version on wifi. First, create an OpenCPN TCP or UDP output connection stream on the Android device. The computer can then connect to that stream using an OpenCPN input network connection on the same wifi network.
