YoNav! - A simple GPS app that just works!

YoNav! leverages the latest features of the Apple Watch Series 2 to put a cutting-edge waterproof standalone GPS on your wrist. There is no need to be tethered to your iPhone anymore. YoNav! on the Apple Watch Series 2 is 100% stand alone for tracking and telemetry. What sets YoNav! apart is the efficiency of data. There is no clutter, no complicated menus, just a GPS app that works.

YoNav! is perfect for:
--Kiteboarding, surfing, or other water sports

Using the latest features of the Apple Watch Series 2, YoNav! can:
--Track and map your activity
--Display important telemetry during your activity
--Keep track of your sailing starts with a built-in timer that offers haptic feedback during the countdown.
--Track your calories burned during your activity

Track and map your activity
YoNav! will track and map your activity (on iPhone) using color coded tracks to show speed variations. Tracking can be turned on and off from the watch. Tracks can be uploaded to the iPhone once you are back in range.

Display Important Telemetry
All the information you expect from a handheld GPS is at your fingertips. YoNav! can display 1 to 4 separate data fields. Available data fields are speed, course, bearing to waypoint, velocity made good, distance off course, distance to waypoint, and many others. All telemetry can be displayed in the unit system of your choice.

Built in Sailing Countdown Timer
Are you a sailor? Do you want to nail the perfect start? Use the built-in timer to countdown from the duration you choose. Haptic (vibration and sound) feedback occurs at intervals during the countdown. The tracking automatically begins as soon as the timer reaches zero. You can ensure your sailboat is moving at full speed at every start.

Leave all the complicated electronics at home next time you are on water, in the mountains, or just on the go. YoNav! can replace hand held GPS units with a simple yet very effective app.

While the paired iPhone is in range, the GPS of the iPhone is used for tracking. When the paired iPhone is not in range the GPS of the Apple Watch Series 2 is used. Please note that continued use of the GPS running in the background of either device can dramatically decrease battery life.

Not Working

Since downloading this app, it has never fired up. No location LAT/LONG and no maps. I have authorized the app in settings to use location services. What am I missing?

A perfect racing app


First preloading waypoints is trivially easy, you just need to know the Lat/Lon in decimal instead of deg,min,sec but converting between those is easy with a number of online calculators. Then just plug the numbers in (on your phone).

One loaded the waypoints are selectable from your phone. In fact I don't even bring my phone with me. Check the course board, select the first mark, and the app pops up the data you select to show (I like SOG, COG, turn, dtm).

It also has a start timer (with a sync button) to replace the starting watch I used to wear.

I cannot recommend this app highly enough for small boat sailors. Big boats that want to pull telemetry from wifi enabled instruments may prefer a more advanced option. But for small boat sailing this is perfect.



KISS...Keep It Simple Shannon! App is great.. Do what you do and see where ya did it. Simple and relevant information is displayed in a manor that those who are active need...NUMBERS! If you are into navigation and/or performance tracking, numbers are the key, and not frilly little maps. Though there is a map available in the playback which is cool too.
