YoNav! - A simple GPS app that just works!

YoNav! leverages the latest features of the Apple Watch Series 2, 3, & 4 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, 3, & 4 is 100% stand alone for GPS 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 a perfect GPS tracker for:
--Kiteboarding, surfing, or other water sports

Using the latest features of the Apple Watch Series 2, 3, & 4, YoNav! can:
--Track and map your activity by GPS
--Display important telemetry during your activity
--Export your tracks to GPX format for use in most major navigation software
--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. All tracks can be exported off the iPhone in GPX format for use in most major navigation software apps.

Display Important Telemetry
All the information you expect from a handheld GPS is at your fingertips. YoNav! can display 1 to 8 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, 3, & 4 is used. Please note that continued use of the GPS running in the background of either device can dramatically decrease battery life.

Privacy Policy Summary: YoNav! collects calorie workout data while in operation on the Apple Watch and sends the workout data to Apple's Health app. It also collects and stores location information. Learn more about the YoNav! privacy policy at:

Great Idea

The app is really simple and really informative. The timer and alerts at minute intervals is great. I like that at the turn of the wrist I can get 4 stats.

A few issues: the app began crashing every time i would try to navigate so i had to reinstall. It was inconvenient because i had to enter all of the marks from the lake again. The other was after I reinstalled i entered in the 20 or so marks and when i reopened the app, about 1/3 of the marks were not there.

After the first issue i reached out to the developer who responded after some email issues. Very helpful the app just has a few kinks.

Best ever

Adding, naming, and editing waypoints and routes is intuitively efficient.

Makes any other app seem clumsy.

Best method of learning how to properly use the app is to just start tapping, tapping and holding, and generally exploring what the app will do. You will need to engage your brain when something doesn’t appear to work. Ex: vmg requires a destination.

You can change a waypoint in the middle of a route in 10 seconds. Really.


Wish list: share a route and waypoints with fellow YoNav! sailors, full-screen version for iPad.

Apple Watch bug

I want to love this app because it meets all my needs in paper but I bought it for my watch and it’s unusable. Every time I set a waypoint the watch displays info but when I turn my wrist to view it a second time the app crashes and the app either gets really buggy and I have to force quit it. I have to set the waypoint again and have the same bug occur again. Help!

Developer Response ,

Sailguy, we will get you working. Can you send me an email at so we can troubleshoot? We’ve got several thousand current users, I’m sure we can make you one of them. Thanks, Shannon
