About this app

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 manually to see your optimal tacks for the route you are planning.

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. Navionics terms of use: SailTimerApp.com/vectorcharts.html

● 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.

● 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.

● Polar plots: The app comes with a default polar plot for calculating optimal tacks (which you can edit). Plus, it can learn the custom polar for your boat.

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

● 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).

If you are getting this free app and agree that these are helpful and unique features for sailing, please help out other sailors by letting them know, with a quick rating on this version while you’re here.

Started off with a decent marine map, which was good. I have a Navionics subscription so in the settings, I selected charts, and Navionics. The chart it brought up is next to useless and is not my Navionics subscription definition map. The App won't let me go back to the default map that it started with, even after uninstall and reinstall. I've uninstalled the App as the map is no good, not showing any Marine navigation marks. Developers, please improve maps options and Navionics interface.

After downloading the App, three attempts to register on a Samsung S23 Ultra. Blank Screen. The app has now been deleted. Seems the developer has a way to go.
