About this app

Prot-IN is a nutrition tracking app for those who want to take control of their diet without getting bogged down in diets or calorie counting.

TAKE BACK CONTROL

The core idea: to put you back in control. You take a picture of your plate or describe your meal in a sentence. Artificial intelligence identifies the foods, estimates portion sizes, and calculates your macronutrients. EVERYTHING IS CLEARLY DISPLAYED: you observe, you understand, then you take action.

A BALANCED, SCIENCE-BASED APPROACH

Prot-IN targets optimal protein intake—as defined by nutritional research for your profile and activity level—within a balanced plan. Protein plays a vital role in building our cells and is essential for our health. Carbohydrates are carefully monitored without being demonized: they fuel your brain and muscles, and your carbohydrate budget adjusts to your activity level.

What you track daily:
• Protein, carbohydrates, fats
• Vegetables with every hot meal
• Omega-3s over the week
• Weight and physical activity
• Overall health (glycemic load, ultra-processed foods, gut microbiota, heart health, inflammation)

Counting calories is meaningless: everyone is different, and a raw number says nothing about the quality of a meal, the context of the day, or the regularity of a week. Prot-IN tells a more accurate story.

STRESS COUNTS AS MUCH AS WHAT'S ON YOUR PLATE

A strict, anxiety-inducing, constantly monitored diet itself worsens the benefit/risk balance. And it's not sustainable in the long run. Well-being is part of a whole: what you eat, how you move, and how you experience your relationship with food. A dessert on Sunday, a drink with friends, cheese at a restaurant—coherence is achieved over the course of the week, not in a single meal.

THEY USE IT, THEY CHANGE

Across all our beta testers—health, weight loss, muscle gain, sports—everyone reports a spontaneous change in their eating habits, without any effort on their part. Simply reviewing their daily logs is enough to guide their choices.

Observe, understand, act.

TWO PHASE 1, ONE GOAL

Phase 1 — Observe.
You discover your actual habits. Without constraints, without restrictions. The app learns your rhythm, your preferences, your practices. After this observation period, a data-driven report shows you where you stand.

Phase 2 — Take control.
You take charge. The calendar becomes your goal: in your own way, you adapt your methods, the ones that work best for you, to reach your objectives. Prot-IN becomes a discreet tool that confirms or questions, never a judge.
