That's the whole pitch. No barcodes, no database spelunking, no twelve-field forms. Say what you ate the way you'd say it to a friend — the calories and macros are on the page before you've cleared the table.
Type it. "chicken salad, big bowl" is enough. Amounts help, but it estimates what you skip.
Say it. Hold the mic and talk. Done. The voice note becomes a logged meal.
Snap it. Point the camera at the plate. Or the label. It reads what's there.
