What makes it different

Your food log is an MCP server. Connect Claude, ChatGPT or any MCP client and just say what you ate. 73 tools cover logging, foods, recipes, goals, weight, sleep, supplements, analytics and the AI task queue — OAuth-protected, so the agent only ever sees your data.

On-device label OCR and photo cut-outs. No barcode? Point the camera at the nutrition table. A shared Kotlin parser plus ML Kit reads it on Android, a native Vision-based parser on iOS — nothing leaves the phone either way. Food photos get the same treatment: one toggle cuts the food out of its background (ML Kit subject segmentation on Android, Vision on iOS), sticker-style.

Offline-first, for real. Every client writes optimistically to a local store (Dexie on web, SQLDelight on Android, SwiftData on iOS) and drains a sync queue with idempotency keys and last-write-wins conflict resolution. Log on a plane; it reconciles when you land.

43 extended nutrients. Beyond calories and the five macros — vitamins, minerals, amino acids — sourced from Open Food Facts and your own database.

Actually native. Not a wrapped web view: Jetpack Compose on Android, SwiftUI on iPhone, plus a Wear OS app, an Apple Watch app, home- and lock-screen widgets, and Health Connect / Apple Health integration.
