Trio: Nutrient Tracker

Many nutrition apps track pretty much everything. They overwhelm you with information and features. They complicate. Trio tracks three things: protein, calcium, and fiber. No calorie counting, no weight tracking, no guilt. WHY THESE THREE? Calcium is the primary building block of bone — 98% of your body's calcium is stored in your bones. Protein makes up roughly 30% of bone tissue and is essential for maintaining muscle mass as you age — stronger muscles mean better balance and fewer falls. Fiber supports the gut microbiome, which plays an important role in overall nutrient absorption and metabolic health. Together, they form a nutritional foundation for staying strong as you age. CALCIUM FROM FOOD FIRST, NOT JUST PILLS Told to get 1,000–1,200mg of calcium a day? The guidance is clear: food first, supplements only for what's left. But how much calcium does your food actually deliver? Trio shows you — and helps you spread it across meals so your body absorbs it. LOG A MEAL IN UNDER 30 SECONDS Type a food, scan a nutrition label, or photograph your meal. Trio fills in the numbers. SEE WHERE YOU STAND AT A GLANCE Three animated rings show your daily progress. Tap any ring for food suggestions to close the gap. Set your dietary preferences — vegetarian, dairy-free, gluten-free, and more. Suggestions adapt to what you actually eat. ASK ANYTHING Does coffee affect how I absorb calcium? Is plant protein as good as animal protein for muscle? The built-in nutrition assistant explains things clearly — no jargon, no lecture. YOUR DATA STAYS ON YOUR DEVICE No account required. Everything you log lives on your phone, private by default. BONE HEALTH MODE An optional mode that goes deeper on bone health: recommended targets based on your age, sex, height, weight, and activity level, a gentle note when one meal contains more calcium than your body can efficiently absorb at once or when a day goes over the recommended maximum, food suggestions that favor bone-supportive choices, and a nutrition assistant that keeps your bones in mind. Trio is for anyone who wants to eat intentionally for long-term health. It's less about hitting three perfect numbers than about learning what's actually in your food — so eventually you don't just know whether you hit your target, you understand why. Use it on its own, or alongside whatever health app you already use. Built to educate and encourage, not restrict. It's about what you eat — not what you don't.
