Can I use Waterspeed on Apple Watch along with other apps? (rarely it crashes)

Waterspeed, during a navigation, uses a lot of resources of your Apple Watch, in order to track very precisely. Using other apps (then sharing GPS and resources) can affect performances and sometimes, even if rarely, it can crash Waterspeed and the other apps. It is basically a limitation of the hardware of the device.

During a regatta or a race, you can start a countdown. Countdown feature can be activated or hidden from the Settings page within the app.


Adjust the minute amount using the '+'/'-' buttons, also if the countdown started. On Apple Watch, use the Crown to adjust this value, if, from the Settings page, you have disabled the 'Crown to start' switch.

Sound on Start (Apple Watch)

From the Settings page of your watch app, you can choose to activate sound and vibration when an activity starts and stops.


GPS accuracy, info, and tips (and 'Low accuracy filter' - 'Low power' setting)

Waterspeed uses the internal GPS of your device to track Speed, Heading, to save the track and calculate statistics. On Apple Watch 2 or higher uses the internal GPS (if iPhone is not connected). Waterspeed applies filters to the GPS data received from the system, in order to avoid mistakes and adapt that to the Watersports behavior. If you want to remove all filters, choose the 'Average' screen mode.


Please, be sure to allow the access to the GPS (Location) in the general settings of your iPhone and your Apple Watch.


NOTE: if you experience some big mistake in your track, using the Apple Watch alone, please try to put it in Flight mode, to avoid any connection, that can be the reason of the wrong position registered (see pictures).


NOTE 2: In case of mistakes or if you forget to stop the GPS when you are back to the land, use the Cut Tool available inside the Navigation Details view (see the related article).


Waterspeed can also work with an external GPS that is natively integrated with your device and compatible with iOS 10 or higher (for example to use an iPad that doesn't have the internal GPS).


Before start tracking your session, be sure to wait until there is a GPS signal. If not, open iOS Maps, then open Waterspeed and let it search for a few minutes to lock onto a GPS signal.

Make sure you have enabled the GPS in the Location Services setting for Waterspeed of your device.


The standard configuration of Waterspeed uses a good accuracy value (<32 meters) in order to track your activity. For a better quality/accuracy (<16 meters) and a precise tracking of every single point, disable 'Low accuracy filter/Low power' setting. It may cause to run out of battery quicker and there is no guarantee the device will find and keep a GPS signal during the entire activity. Also, High Power mode doesn't apply any filter so it can get more errors from the GPS (with no filters the GPS signal keeps moving position even if you are stopped).

NOTE: If you want to remove all filters and get the Max power, choose the 'Average' screen mode.


When starting please try to avoid the following areas:

  • High buildings

  • Deep forests

  • Areas where it's very cloudy

If a GPS signal is missing for more than 60 seconds (while tracking an activity), Waterspeed will play a sound and a vibration. You can disable this feature from the Settings page.


Be aware that just because some maps app like Google Maps, Apple Maps etc. may show your location on the map, this does not mean that the device's GPS is functioning properly or that a GPS fix has been obtained. The data used to show your location on the map may be based on cellular network, Wi-Fi signals or very poor accuracy.


Please note: continued use of GPS running in the background can dramatically decrease your battery life.


'NO GPS' Alert

If GPS signal is missing for more than 60 seconds (while tracking an activity), Waterspeed will play a sound and will vibrate. Disable this feature from the Settings page.


Battery life on Apple Watch

Based on thousands of users experience and how many apps are running at the same time, you should be able to track activities continuously for 5 hours on Apple Watch 3 and more on higher versions (following the below suggestions to save battery). It is usually enough for tracking a Water Sports day.

If you need to get the maximum from the battery life you should set your Waterspeed on Apple Watch as:

- Low GPS Power active

- Dark mode activated

- 'Save Workout' deactivated

- 'No GPS Alert' deactivated

- 'Distance alarm' deactivated

You can also see here some advice for the general settings of your watch:

Limit of 10000 points for the view of the map on iPhone

Due to a memory limitation, Waterspeed can show up to 10000 points on the map for a single track (also in the sharing of the map). This limit usually means an average of 100 Km of tracking at 6 Kn of speed. All data and all other tools will be available, including SPLIT of the track.


Limit of 9900 points for a track on Apple Watch

Due to a memory limitation of the Apple Watch, Waterspeed can save up to 9900 points for a single track. Once reached this amount of data, it will be asked to save and start a new activity.

This limit usually means an average of 10 hours of tracking at 15Kn of speed.

Delete/Undelete tracks

Waterspeed doesn't delete tracks but marks them as deleted. So they will be always available and can be restored from the 'Undelete' button in the Diary page.
