I’ve been developing a foiling app for the Apple Watch for some time now, and it’s getting close to completion. It would be amazing to get it into the hands of real foilers for proper testing. I’m particularly looking for prone surfers and dock starters to help fine tune the algorithms for those recording modes, but all foilers are welcome! If you’re interested in testing the app or have suggestions for features you feel are missing from the apps you currently use, send me a DM!
Nice!
A few questions
Can you use this without being in range of your IPhone?
Can you somehow export the info to your PC to review there rather than on phone?
You can record sessions using either your Apple Watch or iPhone. The Apple Watch offers a far superior experience and does not require a connection to the iPhone while recording.
I’m planning to add support for exporting tracks in GPX format, which can be imported into many different tools. However, you’ll miss out on many foiling-specific features if you review the tracks in a generic web-based tool. On the iPhone, you’ll get detailed data, including foiling stats, jibe and tack analysis for wingfoiling, wave and linked wave counts for prone foiling, and tailored insights for dock starts if that’s your passion. Next step is adding analysis for dw but that will come later.
Thanks for answering. Looks like you are well along in the process so congrats on that!
Here is a tool I did for myself, maybe some insight would be interesting for you.
I dont have an Iphone or watch to test your app sadly, so my tool from watch GPX will have to do for now, 
Hi Jenz,
I regularly Prone and Wing with a bit of SUP, Kite or Dockstart thrown in every now and then. I use or have used Strava, Waterspeed and Hoolan for Wing/Kite and I use Dawn Patrol for Prone. I have an Apple Watch Ultra 2.
All of these apps have some changes that I would love to see implemented, so happy to take part in the Beta testing.

A test user wanted to know how far they are from the starting point to determine when it’s time to deflate the wing and switch to DW mode. I think this feature could be quite useful for other types of sessions as well, especially for gauging where you currently stand on the FAFO chart.
The dock start algorithm and user interface are ready for testing. I’ve ordered a dock start board and am prepared to face certain humiliation at a nearby dock. 
Looks great! How much will it cost on the App Store?
Would it be possible to display telemetry from other devices? Via wireless protocol eg Bluetooth or ESP-NOW/wifi? For example show the amps drawn by my ESC or other operational data.
If @ludwig_bre is still planning to add BLE support to the next-generation BREmote, my plan is to integrate support for pulling telemetry from the remote. The available data will depend on what the receiver supports. As far as I know, the current version only communicates with VESC speed controllers, so the new version may have the same limitation.
I’m considering adding a custom BREmote screen on the Apple Watch to display basic data such as current, max current, and total amps. On the iPhone, I’d like to create a more detailed view that further breaks down the data, including metrics like the average amperage drawn at different speed intervals—for example, amperage at 20–22 km/h, 22–24 km/h, 24–26 km/h, etc. This will provide concrete data on the efficiency of different foils and propellers at various speeds.
There’s an image of the watch app with a mockup of the interface here:
I don’t have any concrete plans to add support for other devices, but I’m always open to suggestions.
The pricing will be $19.99 for a one-year subscription, with the first month free, allowing you to try the app before committing to a purchase.
Track coloring has gotten a huge overhaul in recent days. What do you think?
