Macroline: Calorie Tracker

Macroline is a macro and calorie tracker built for the AI era. Just say what you ate, scan a barcode, or search millions of foods that always tell you where the data came from. Now with a clean, redesigned home that puts your whole day at a glance.

LOG WITHOUT THE BURDEN
- Describe: say "I had a chicken caesar wrap and a coke" and Macroline parses it into structured entries. No ten-tap forms.
- Scan: point your camera at any barcode. We resolve against USDA, OpenFoodFacts, and our crowd-verified database.
- Search: type-ahead with brand, alias, and fuzzy matching.
- Recents: you do not eat a thousand foods, you eat the same ones on repeat. Re-log your usuals in a couple taps, no searching.

PROVENANCE YOU CAN TRUST
Every food shows its source: USDA authoritative, brand labels, OpenFoodFacts community, or a clearly marked AI estimate. Tap the badge to see exactly where the numbers came from. We do not fudge the data, an AI estimate is always labeled as one, and you can always adjust it.

HIT YOUR PROTEIN
Set a protein target with the built-in calculator and track toward it every day. (It is a starting point, adjust it with your dietitian.)

GLP-1 AND WEIGHT-LOSS MEDICATION TRACKING
Track semaglutide, tirzepatide, naltrexone-bupropion, phentermine, and more. See your dose-in-system over time, log side effects, and watch how it lines up with your week. (Macroline does not provide medical advice.)

WEIGHT TRENDS, NOT DAILY NOISE
Sync your weight with Apple Health and watch the trend over weeks instead of obsessing over the daily number.

CONNECT YOUR AI ASSISTANT
Macroline ships with an MCP server, so you can connect Claude or other AI tools to log meals, query your diary, and ask "how much protein have I had this week?" straight from your assistant.

USE IT ANYWHERE
Macroline also runs in your browser at my.macroline.app, so your diary follows you across your devices.

NO DIET SHAME
No streak pressure. No fasting nudges. No "you ate too much" messages. Tracking is for awareness. What you do with it is up to you.
