The Apple Watch can be used on a Kinomap as a heart rate sensor.
Note that this doesn't work with an iPad, you need to use an iPhone.
First, you need to pair your watch with Kinomap. To do this, you need to go to the "Profile" tab, then to the "Settings" option, then to "Equipment management", and finally press the gear displayed on your equipment. Once on this screen, press the "Add sensor" button. Bluetooth discovery should now show your watch:
Once paired, you'll need to launch the Kinomap application from your watch and select the workout on your phone. You'll need to take your watch out of standby mode when you launch your session.
If you see a green "Start" button, press it:
When your workout begins, your watch's sensors should light up and you should receive your data a few seconds later.
To stop, you'll need to shut down Kinomap on both your phone and your watch.
