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.
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."
Recommendations aren't static. TUNA finds the pattern and builds a custom protocol.
How logging works
Log meals in seconds — however you prefer.
Snap a photo
TUNA's AI identifies the foods, estimates quantities, and breaks down the nutrients.
Describe it in natural language
Type: "grilled salmon with broccoli and lemon butter" and TUNA builds the meal.
Precision search
A powerful nutrition database with smart indexing for foods, brands, and recipes.
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.
Tune to your bloodwork
Upload your labs. TUNA turns biomarkers into nutrient priorities.
Your bloodwork tells the real story. TUNA reads it and adapts your daily nutrition around what your biomarkers actually show — not what an average says you should need.
How it works:
- Upload metabolic, lipid, iron, hormone, or comprehensive panels
- TUNA flags out-of-range biomarkers and sets daily limits or targets accordingly
- See exactly which foods to add or limit — backed by your labs
- Track changes over time as your numbers improve
- Re-upload new panels and your nutrient plan updates automatically
Stop guessing. Eat for the biology you actually have.
For athletes, biohackers, and longevity seekers
Precision nutrition for people who want to feel and perform better.
Whether you're training for endurance, lifting, prioritizing longevity, or simply optimizing energy, TUNA gives clarity grounded in physiology — not trends.
You'll see how meals influence:
- Recovery and soreness
- Glycogen replenishment
- Sleep quality and HRV
- Inflammation
- Mental clarity
- Hormone balance
TUNA turns complex data into actionable patterns.

- Meal streaks and logging consistency
- Achievements (e.g., iron mastery, omega balance, recovery streaks)
- Personalized insights based on your patterns
TUNA gives you a clean dashboard that shows progress in a fun and intuitive way.
