Choose Hexis if you want guidance: colour-coded meals, recipes and a platform your coach also uses. Choose Avitu if you want exact gram targets per meal and per ride, want to see the formula behind every number, and train with Intervals.icu, Strava, Garmin or Wahoo.

The core difference: coach or instrument
Hexis simplifies fueling. Its Carb Coding labels each meal as high, moderate or low carb, so you don't need to count. For many athletes that's exactly right: less friction, fewer numbers.
Avitu goes the other way. It treats nutrition like a power meter treats training: it reports exact numbers and shows how each one is derived. Your daily energy target comes from your athlete profile, your day structure and the training load of every session. Carbohydrates are distributed around your rides. You can audit every step.
If you already analyse your power files in Intervals.icu, you will probably want the same level of detail on the nutrition side.

FAQ
What is the main difference between Avitu and Hexis?
Hexis works like a nutrition coach: it colour-codes meals as low, medium or high carb (Carb Coding) and suggests recipes. Avitu works like an instrument: it calculates exact gram targets for protein, carbohydrates, fat and fiber per meal and activity from published physiological formulas, and shows the formula behind every number.
Is Avitu a good Hexis alternative?
Avitu is a good Hexis alternative if you want exact, auditable gram targets, use Intervals.icu, Strava, Garmin Connect or Wahoo, and prefer a lower price (€4.99/month or €49.99/year, versus €24.99/month or €129.99/year for Hexis). If you want recipes, meal plans or a coach platform, Hexis is the better fit.
Does Avitu integrate with TrainingPeaks?
Not directly. Avitu integrates with Intervals.icu, Strava, Garmin Connect and Wahoo. Many athletes sync TrainingPeaks workouts to Intervals.icu, which Avitu then reads for planned training load.
Does Avitu use AI?
No. Avitu is deterministic: the same inputs always produce the same targets. Targets are derived from established formulas such as Mifflin–St Jeor and training-load-based carbohydrate models, and every calculation can be inspected in the app.
