Made for athletes, biohackers, and everyday humans.

TUNA is not a simple calorie tracker — it's a nutrient engine that helps you understand what your body needs, how your meals measure up, and how your nutrition changes with sleep, stress, workouts, hormones, and life.

TUNA App Interface

What makes TUNA different

TUNA isn't another food log. It's a nutrient intelligence system.

Most apps count calories. TUNA looks at what your body needs — from iron absorption to omega balance to nutrient synergies and blockers.
It adapts to your physiology, your habits, and your goals.

TUNA helps you:

  • Optimize nutrients that affect energy, mood, recovery, and focus
  • Understand nutrient interactions (like how vitamin C boosts iron absorption, or phytates block minerals)
  • Track inflammation inputs (e.g., omega-6:3 ratios)
  • See how sleep, movement, fasting, and workouts shift nutrient demands
  • Eat in a way that supports performance, longevity, and whole-body resilience
  • Optimize fertility, pregnancy, postpartum, or menopause
  • Look good, feel good

It's the nutrition app for people who want to understand "why," not just "how much."

The nutrient intelligence engine

Your daily nutrient score, explained.

TUNA shows how each meal contributes to — or works against — your goals.
Every nutrient has a role. Every choice affects absorption, synergy, or metabolic demand.

TUNA evaluates:

  • Iron, zinc, and magnesium bioavailability
  • Omega-6:3 inflammation balance
  • Meal timing, glycogen replenishment, and fasting
  • Supplements, vitamins, protein powders and amino acids
  • Electrolytes, sweat loss, and hydration
  • Choline, DHA, glycine, and other performance-critical nutrients
  • Fiber types and microbiome effects

Go beyond nutritional labels with scientific scoring and adjusted recommended daily allowance (RDA) that adapt to your actual needs.

Built for Life

Your nutrition needs aren't static — TUNA adapts with you.

TUNA accounts for the factors that actually change nutrient requirements:

  • Sleep quality + circadian rhythm
  • Fasting windows + metabolic state
  • Workouts, steps, intensity, recovery
  • Stress load
  • Hormonal phases
  • Menstrual cycles
  • Pregnancy
  • Postpartum
  • Perimenopause + menopause

No matter your season of life, TUNA adjusts recommendations intelligently.
