Apple Watch
watchOS 10 or later
Your next feed and a countdown on your wrist, with a buzz when it is time to eat. No head unit needed, and you can record the ride as a cycling workout in Apple Health.
1
Install StemNotes on your iPhone, then add it in the Watch app.
2
Open StemNotes on your iPhone once. The watch links itself.
3
Pick a session on the watch and tap Start.
Apple Watch Series 4 or later.
Then pair it to
your phone.
Connect TrainingPeaks or intervals.icu first. That is where your sessions come from, and the device rows in the app stay locked until one of them is connected.
Then open Settings, Connected Accounts, and pick Garmin or Hammerhead. Enter the short code your device shows you. That is the whole pairing. Apple Watch links itself once StemNotes is open on your iPhone. If it doesn’t, tap Pair with code on the watch.
All three are free to install. The fuelling itself needs StemNotes Pro, because that is where the plan comes from.
Critical power
Don’t know your CP?
Every fuel plan starts from your critical power. If you have never tested, this is the session Andy uses: a three minute effort and a twelve minute effort, thirty minutes apart. About seventy minutes door to door, and the last thing you will want to do again for a while.
Ride it, then put the number into Settings. Every plan updates from there.

Both files contain the same session.
Switch ERG off. Both efforts are maximal, and the power targets in the file are only there to build it they are not what you ride to. Start each one conservatively enough to finish it empty.
