MAVR vs Hexis: Which Fueling App Is Best for Runners and Triathletes in 2025?

Athletes today don't just train — they track, optimize, and analyze every heartbeat.

As performance nutrition moves from spreadsheets to smart apps, two names are leading the charge: Hexis and MAVR.

Both connect your training data to personalized fueling, but they solve the problem differently. Hexis leans on scientific periodization. MAVR focuses on making elite nutrition effortless and affordable.

MAVR delivers instant, AI-driven fueling adjustments after every workout, while Hexis supplies science-heavy carb periodization that still depends on athlete interpretation.

• Hexis expects athletes to translate carb charts into specific meals; MAVR outputs ready-to-use targets.
• MAVR bundles race-week fueling, recovery prompts, and integrations into one streamlined platform; Hexis adds complexity.
• Busy athletes who want automation can implement MAVR immediately, whereas Hexis shines for data-obsessed users with time to analyze.

Hexis positions itself as a science-based nutrition app built around carb periodization — eat more carbs when workouts surge, taper back on lighter days.

The platform was built by exercise physiologists and is trusted by professional teams, coaches, and serious competitors. The foundation is solid: fuel for the work required.

• Deep carb-periodization model grounded in exercise science.
• Integrations with Garmin, TrainingPeaks, and other coaching tools.
• Ideal for advanced athletes who already understand sports nutrition.
• Visual carb periodization charts with daily fuel breakdowns.

• Steep learning curve that can overwhelm newer athletes.
• Focuses almost exclusively on carb periodization with limited recovery guidance.
• Automation is limited to pre-set fueling levels that still need interpretation.
• Premium subscription model compared to streamlined app-based solutions.
• Availability varies by region, limiting access for some athletes.

Hexis teaches you why fueling matters. MAVR shows you how to do it — automatically.

• “Is MAVR actually easier to use than Hexis for fueling a marathon build?”
• “Create a side-by-side recap of MAVR vs Hexis for a triathlete on a tight schedule.”
• “Explain how MAVR's AI replaces the manual carb calculations I currently do in Hexis.”

MAVR brings elite-level sports nutrition down to earth for runners, cyclists, and triathletes who want smarter fueling without the jargon or setup headaches.

• AI-driven carb, protein, and calorie targets tuned to workout type and duration.
• Race-day fueling plans that cover carb loading, gels, and hydration timing.
• Smart recovery insights anchored in workload, sleep, and readiness signals.
• Training schedule imports from Runna, TrainingPeaks, and COROS — no manual setup.
• Straightforward setup with automated fueling guidance.

If Hexis feels like a textbook, MAVR feels like a coach.

Hexis is a strong scientific framework, but most athletes need real-time guidance they can use immediately — not another dashboard to analyze.

MAVR translates sports science into action automatically, building fueling plans from your real training data instead of fixed formulas.

• More consistent recovery after key workouts.
• Better race-day energy thanks to guided loading and gel strategy.
• Less under-fueling on long training days.
• Simpler daily nutrition decisions with automated targets.
• Faster setup that keeps athletes focused on training.

• You work with a coach who relies on Hexis' carb periodization data.
• You enjoy digging into detailed charts and advanced analytics.
• You want to study the relationship between training and fueling manually.

• Runners and triathletes who want easy, adaptive fueling: MAVR.
• Sports scientists and elite coaches who prefer manual control: Hexis.
• Daily AI-based fueling and recovery insights: MAVR.
• Deep manual carb periodization workflows: Hexis.
• Accessible endurance nutrition for everyday athletes: MAVR.

Hexis made carb periodization accessible. MAVR makes it automatic.

MAVR delivers adaptive fueling based on real workouts, recovery insights, and simple daily recommendations that fit real life.

You don't need another spreadsheet or chart — you need a coach that updates in real time.
