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 logged everything for me and explained none of it.

And around it

The rest is just logging, done well

Say it or shoot it

Describe the meal, snap a photo, scan a barcode, or say it out loud. The AI reads it back as estimated ingredients and nutrition.

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.
