Piato opens October 1.

A private nutrition diary for iPhone and the web. Log the meal with a photo, a barcode, or a sentence.

Piato opens on October 1, 2026. It keeps a diary of what you actually ate, on the iPhone app and at piato.us, under one account.

A photo of the plate is enough to start. Piato names the foods and drafts the calories. A barcode reads a packaged food from Open Food Facts. A sentence, like half a cup or leftover rice, works too. Nutrients are matched to USDA and Open Food Facts records.

The account is private. Sign in with Google on the web. The iPhone app also offers Sign in with Apple. There is nothing to buy inside the app.
