Relffits.

Just say what you ate.

We handle the math while you build real food intuition, until one day you delete the app on good terms.

Why this exists

I spent two years overweight and injured after back surgery, and I got out of it by finally understanding what I was eating. I'd used every calorie counter, macro app and barcode scanner out there. They log everything and tell you nothing.

So I built the one I wanted. It teaches you to read your own food, and it's honest about the endgame: you build the intuition, and one day you won't need the app at all.

What it does

Four things, done properly

AI meal analysis

Snap a photo or describe your meal. Instant ingredients, portions, and nutrition.

Guess before reveal

Estimate the calories before the AI shows its answer. Your calibration report tracks the intuition you're building.

Fullness forecasts

See how long each meal should hold you, then tell Relffits how it went. Forecasts tune themselves to your body.

Restaurant coach

Ranked menu picks for your goals, each with estimated staying power, not just a calorie count.
