Four things, done properly
AI meal analysis
Snap a photo or describe your meal. The AI reads it back as estimated ingredients, portions, and nutrition.
Guess before reveal
Estimate the calories before the AI shows its answer. Your calibration report shows how close your guesses have been.
Fullness forecasts
See how long a meal might hold you, then tell Relffits how it went. Your answers adjust the next forecast.
Restaurant coach
Ranked menu picks for your goals, each with estimated staying power, not just a calorie count.
