Quick answer
- Mavr and Hexis both periodize carbs: they read your training and change what you should eat each day.
- Hexis is built around Carb Codes, a meal-by-meal carb signal, plus Live Energy, which estimates your energy minute by minute, and it plans 72 hours ahead.
- It syncs with Garmin, WHOOP, TrainingPeaks, Intervals.icu, and Apple Health, and its athlete page lists €24.99 a month or €129.99 a year.
- Mavr sets daily carbs, protein, and hydration from Strava, Garmin, TrainingPeaks, Runna, Intervals.icu, or Apple Health, builds race-day plans with carb loading and per-hour carb and sodium targets, and adds Kai, an AI coach for photo and voice logging and questions.
- Pick Hexis if you want detailed carb coding and live energy data; pick Mavr if you want simple daily targets, an AI coach you can ask, and Runna or Strava sync.

Facts about Hexis below come from its official athlete page and US App Store listing, checked in October 2026. Mavr publishes this article, so we have tried to be clear about where Hexis is the better choice.
Hexis: carb codes and live energy
Hexis builds a daily fuel plan from your training load. Its Carb Codes give each meal a carb level, and Live Energy shows an estimate of your energy through the day. It looks 72 hours ahead, so a hard session tomorrow changes what you eat today, and it handles rest, base, threshold, and race days differently.
- Carb Codes: a carb target for each meal that recalculates as training changes.
- Live Energy: minute-by-minute energy estimates that update as you log food.
- Intra-workout fuelling guidance and race-day guidance.
- Food logging from a database of over a million foods, with search, barcode, photo, and Smart Log, where you type or say what you ate.
- Sync with Garmin, WHOOP, TrainingPeaks, Intervals.icu, and Apple Health.
- Price on the athlete page: €24.99 a month or €129.99 a year. Regional prices may differ.
