About StemNotes
The problem
Most riders fuel by feel. Long rides go wrong when the plan is a guess, and hard days need more than easy ones.
Why I built it
I wanted a fuel plan that follows the training calendar. So I built one.
What it does
StemNotes plans carbohydrate for each session in your calendar and lays it out in a fuel calendar. The plan reaches your phone, your watch and your bike computer.
Platforms
iOS, watchOS, Karoo and Garmin.
Proof
It launches on the App Store in November 2026. Until then, you can request beta access on the site.
