Hammerhead Karoo
The Fuel Planner app puts a Next Fuel field on your Karoo and alerts you at every feed.
Pairing a Karoo needs StemNotes Pro and a connected training calendar.
Set it up
Install Fuel Planner on your Karoo. The steps are at stemnotes.io/apps, or tap Download Karoo app in Settings › Connected Accounts.
On the Karoo, open Fuel Planner › Settings › Connect via phone. It shows a code.
In the app, go to Settings › Connected Accounts › Hammerhead, enter the code and tap Connect Karoo.
Within a few seconds the Karoo says "Paired with StemNotes" and shows this week's plans.
Add the Next Fuel data field to a ride page.
No typing your TrainingPeaks login on the head unit: the Karoo uses the same calendar as your phone.
Keeping it up to date
Each time StemNotes refreshes your calendar, it sends the week to your Karoo. The Karoo picks it up when you open Fuel Planner or tap Refresh. The ride runs from the saved week, so you don't need a signal on the road.
Start the ride
Load the session as a workout on the Karoo and start it. The Karoo matches it to today's plan and shows "Fuel plan set". A free ride with no workout loaded gets no plan.
What you see
The Next Fuel field counts down to your next feed, with the grams in large type and what to eat above ("20GEL"). The card gets darker purple as the feed gets bigger against your limit. After the last feed it reads "Fuelling done".
Alerts always fire on the Karoo; there's no setting for them.
To unpair, go to Settings › Connected Accounts › Hammerhead › Disconnect Karoo. The Karoo keeps any plan it already has.
