A fuelling plan for every session, your daily macros and meals, live fuelling notifications on your watch and insights after every workout. All based on your training data, in one free app.
take too few carbohydrates during a race.
get gastrointestinal complaints during long efforts, often from the wrong or too concentrated nutrition.
higher risk of bone injury when you structurally under-fuel.
No two athletes burn through training the same way, so generic fuelling advice was never built for you. DataFuel uses your real training data to personalise your fuelling plan and the supplements we recommend, so every recommendation is built around how you train, not what works for everyone else.
Months of training can be undone by getting your fuelling wrong. Too little energy does not just cost performance. It slows recovery, limits adaptation and increases injury risk. We make sure your nutrition supports the work you have already put in.
Your training and goals change throughout the season, and your fuelling should too. That is what the app is for: a fuelling plan for every session, four scores that show whether it worked, and recommendations that shift the moment your training does. You are never left guessing what is right next.
Free on the App Store and Google Play.
Set your goals, your diet and your race, then link your wearable or Strava.

“I went from 45 to 75 grams an hour over eight weeks without a single bad stomach. I would never have dared to push that on my own.”
“I no longer have to search across ten different shops. Everything is in one place, matched to my training.”
“Because of DataFuel I started paying attention to hydration and electrolytes, something I used to underestimate.”
“Before DataFuel I did not really know what to take, or when. Now I finally have clear direction.”
