SailTimer™ vs KWINDOO Tracking for sailing

For all types of boats. Beautiful marine weather animations: • Crowdsourced wind maps for the most accuracy and highest resolution. • Marine weather forecasts from Weathernews Inc. (WNI) with maps of precipitation, visibility, air & sea temperature, wind, waves/swell & ocean currents. • AI models of ocean currents and marine weather from Amphitrite. There are lots of weather services and apps, but they all use the same satellite weather forecast. Low resolution, low accuracy, and only updated 4 times per day. Weather satellites are 500 to 22,000 miles up in space. Crowdsourcing is changing marine weather. Why rely on satellite imaging, when you can use actual measurements from other boaters? In coastal areas, we archive these to map wind flow for more accuracy. Crowdsourced weather maps like these have never been possible before. A wind sensor measures local wind around your boat, but now you can also know the wind and sea state up ahead or around the next point. FEATURES FOR ALL TYPES OF BOATS: • View your route with free aerial photos and land maps worldwide. If you have the Navionics Boating app, you can import worldwide Navionics charts here with a yearly subscription. • The weather map animations each have low-cost monthly/yearly subscriptions with a free 7-day trial. • Hourly weather tables for crowdsourced wind and WeatherNews Inc. (WNI) weather maps. Tap on a certain hour to move the weather animation to that time. • Create and rename waypoints by tapping or importing a list. Save, import or email your GPS track. • All maps and charts in the app can be used offline. • The white crosshair icon in the top left is the “Follow-Me” button. If tapped, 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. • Your device will not go to sleep when the app is open, to allow you to continue to monitor your progress on the chart. You can also continue to track your movement with the app running in the background or when the device is asleep (unless you hard-quit). (Note: Continued use of GPS running in the background can dramatically decrease battery life. This app may use your location even when it isn’t open, which can decrease device battery life.) FOR SAILBOATS: Whether cruising or racing, it is important to be able to determine the best heading on all points of sail. GPS chartplotters do not calculate tacking distances. But if they do not know the distance you will travel, how can they calculate your correct ETA? This is the only product that calculates your optimal tacks using your tacking distance and polar plots. Details at www.SailTimerApp.com. The SailTimer app gives you a quick and easy display of your optimal tacks and TTD® (Tacking Time to Destination). • Use our wireless Wind Instrument or wired Ultrasonic (www.SailTimer.co) to see wind direction, angle & speed. Enter a waypoint and your optimal tacks will update automatically as the wind changes. • Bring in wind data from any other wind sensor on wifi from NMEA 2000 or 0183, using our low-cost Air Link™ (https://wi-rb.com/airlink). • Custom polar plots: When using a wind sensor, the app can learn your sailboat's unique speed profile on all points of sail, for the most accurate tacking results. • Switch the display to the port or starboard tack to avoid obstructions, or let the app automatically display the tack nearest to your current heading. • Audio Navigation: when using the wireless Wind Instrument, optionally hear wind conditions or boat speed when they change by more than a set amount. • Convert from Apparent to True wind direction, angle & speed.
