Liv - AI Food Life Scanner

Every bite you take adds or removes minutes from your life.

Liv turns the food you eat into a number you can feel: minutes of life gained or lost. Not
calories. Not macros. Not letter grades. Minutes.

Point your camera at any meal. In seconds, Liv tells you exactly how that food impacts your
lifespan — backed by peer-reviewed epidemiological research.

HOW IT WORKS

Scan any food with your camera. Liv's AI identifies what you're eating, estimates the nutrition,
and calculates your lifespan impact using the microlife framework from Spiegelhalter (2012) and
the Health Nutritional Index from Stylianou et al. (2021).

One banana: +14 minutes. A hot dog: -30 minutes. A salmon fillet: +15 minutes. These aren't
arbitrary scores — they represent per-serving impact on total life expectancy, derived from the
same data used in public health research.

WHAT LIV TRACKS

• Fruit & vegetable servings — each one adds ~7 minutes
• Oily fish (omega-3) — +15 minutes per serving
• Processed meat — -30 minutes per serving
• Red meat — -15 minutes per serving
• Saturated fat, trans fat, sodium, added sugar — scaled penalties
• Fibre — protective bonus

Every factor stacks. Your daily total shows whether today added to or subtracted from your life.

PERSONALIZED TO YOU

Liv adjusts scores based on your age, gender, and body composition. The same meal impacts a
25-year-old differently than a 60-year-old — because the science says so.

FEATURES

• AI food recognition — point, scan, done
• Barcode scanning — instant lookup for packaged foods
• Daily life score — see your running total of minutes gained or lost
• Personalized scoring — adjusted for your age, gender, and BMI
• Meal library — discover meals ranked by lifespan impact
• Streaks — build the habit of scanning everything you eat
• Beautiful, minimal design — no clutter, just clarity

WHY MINUTES?

Calories tell you about energy. Minutes tell you about life. When you see that a bag of chips
costs you 18 minutes but a handful of almonds earns you 9, the choice becomes visceral. That's the
point.

Liv doesn't lecture. It shows you a number and lets you decide.

THE SCIENCE

Liv's scoring is built on:
• Spiegelhalter (2012) — the microlife framework for communicating health risks
• Stylianou et al. (2021) — the Health Nutritional Index (HENI)
• Fadnes et al. (2022) — dietary impact on life expectancy
• Global Burden of Disease dietary risk factors

Every factor, every multiplier, every minute is traceable to published research.
