🎙

Speak it. Log it.

"I had a chicken caesar wrap with extra parmesan and a coke." Macroline parses natural language, finds the right foods, and logs the right portions. Voice or text, your call.

🔍

Honest data.

Every food links to its source — USDA, manufacturer pages, official restaurant nutrition. Tap any number to see where it came from. No more bad community entries with wrong macros.

🔌

Bring your own AI.

Macroline runs as an MCP server. Connect Claude, ChatGPT, or any MCP-compatible assistant. Log dinner from your phone, your desktop, even your IDE.

Every number, sourced.

Macroline is built on a different principle than MyFitnessPal: show your work. Every food row in our database carries a provenance tier and a citation URL.

Authoritative

USDA FoodData Central, manufacturer pages, official chain restaurant nutrition. The gold standard.

Computed

Recipe foods derived from authoritative ingredients with summed macros. Math is verifiable.

Estimated

AI-researched from cross-checked sources when no official data exists. Cited and flagged.

Unverified

User-submitted entries, awaiting community confirmation. Visible but never silently trusted.

Coming soon to the App Store.

Macroline launches first on iOS via TestFlight. Drop your email and we'll let you know.
