SailTimer™

Whether you are going out fishing, waterskiing, sailing or crossing open water, this app shows you an animation of wind direction and wind speed, and contour lines of precise wind zones. The app was originally designed to help sailboats navigate. But now the charts and crowdsourced wind maps are useful for power boats, sailboats, kayaks, kite surfers...

The marine weather forecast comes from satellite imaging which is not very accurate (and does not actually measure the wind). Fortunately, with years of crowdsourcing from sailboats, we have growing coverage with crowdsourced wind maps. In coastal areas, we archive the crowdsourced wind data to map how the wind flows around islands and into channels. Then even if there is not live data there at a certain time, we still know how the wind will flow there.

Crowdsourced maps like this have never been possible before. A wind sensor tells you local wind around your boat, but now you can know the wind and sea state up ahead or around the next point.

App Instructions and Unique Features:

● Worldwide vector charts, Google Maps and aerial photos. If you have the Navionics Boating app, you can import your Navionics charts here with a yearly subscription.

● The white crosshair icon in the top left is the “Follow-Me” button. If clicked, it turns blue and keeps your location in the center of the screen as you move. Unselect when not moving to look around the map, and when you want to zoom in and out.

● GPS track can be displayed under options. Save a screenshot to view or share your trip later.

● The Wind Zones button has a small in-app subscription to see precise contour lines of wind zones or an animation showing wind direction and speed.


Features for Sailboats:

Standard GPS chartplotters and mapping apps do not account for sailboat tacking distances. But if they do not know the distance you will travel, how can they calculate your correct ETA? SailTimer gives you a quick and easy display of your optimal tacks and TTD® (Tacking Time to Destination).

If you have the wireless SailTimer Wind Instrument™ (www.SailTimer.co) connected to your phone/tablet, your optimal tacks will update automatically in this app as the wind changes. Or you can manually enter wind direction and wind speed to see your optimal tacks for the route you are planning.

● Waypoints: Use the Tacking Routes button in the upper left to add new waypoints or to select from a list.

● Just select a route to see the optimal tacks to each waypoint. For wind, use the wireless SailTimer Wind Instrument™ (https://www.SailTimerWind.com) so that your tacks update automatically as the wind changes -- or enter wind speed/direction manually.

● When you pass a waypoint, press the > on the right side of the screen to go to the next waypoint. (Press < on the left side to see optimal tacks to the previous waypoint).

● The optimal tacks are the same headings whether you do the port or the starboard tack first. See the FAQs at http://sailtimerapp.com/FAQ.html for hints about avoiding obstructions by switching to the other tack.

● Polar plots: The app comes with a default polar plot for calculating optimal tacks (which you can edit). Plus, it can learn the custom profile for your boat's speed on different wind angles (polar plot).

● Wind gauge button in upper right when using wireless Wind Instrument shows True and Apparent Wind Angle and Direction (TWD, TWA, AWD, AWA) in True-North and Magnetic-North reference.

● Audio feedback is available by tapping screen to hear wind conditions. (More audio features are available in the SailTimer Wind Gauge app).
