About this app

Stop guessing your fuel. StemNotes turns your planned workouts into a clear, personalised carb plan for every ride: how many grams to take, and exactly when.

Connect TrainingPeaks or intervals.icu and StemNotes reads your upcoming sessions, then builds a fuelling plan from your power, duration and intensity. See your grams-per-hour target, a timed feed schedule, and your total carbs at a glance.

WHAT YOU GET
• A per-session fuel plan built from your real workouts
• Timed feeds so you never miss a gel or bar
• Grams-per-hour and total-carb targets tailored to you
• Planned vs actual: log what you ate and see how it compared
• Your plan on your bike computer, not just your phone

RIDE WITH IT
• Garmin Edge: the StemNotes Fuel data field shows your next feed, a countdown, and flashes when it's time to eat
• Hammerhead Karoo: fuel alerts right on your ride screen
• iPhone and Android: plan, review and adjust anywhere

BUILT FOR CYCLISTS
Whether you're chasing a first century, racing, or just tired of bonking, StemNotes takes the guesswork out of fuelling. It's periodised session by session, based on what you're actually doing, not a generic number.

HOW IT WORKS
1. Connect TrainingPeaks or intervals.icu
2. StemNotes builds your fuel plan for each session
3. Push it to your Garmin or Karoo and ride
4. Log what you consumed and refine over time

Fuel every session. Download StemNotes and ride fuelled.
