Macroline
Track macros, calories & GLP-1
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Log meals by voice, scan barcodes, track GLP-1 doses. Every food shows where the numbers came from. No streak pressure. Free with optional Pro at $4.99/mo.
Macroline is a macro and calorie tracker built for the AI era — log a meal in a sentence, scan a barcode in seconds, or search a database of millions of foods that always tells you where the data came from.
INPUT FOUR WAYS, NO BURDEN
• Describe — say "I had a chicken caesar wrap and a coke" and Macroline parses it into structured food entries. No ten-tap forms.
• Scan — point your camera at any packaged barcode. We resolve against USDA, OpenFoodFacts, and our growing crowd-verified database.
• Search — type-ahead with brand, alias, and fuzzy matching. "clear blue oath" finds Oath's Clear Protein Blue Razz Coconut.
• Voice + AI — power users can dictate complex meals in plain English.
PROVENANCE YOU CAN TRUST
Every food row in Macroline carries a source: USDA authoritative, brand labels, OpenFoodFacts community, or AI-estimated. Tap the badge to see where the numbers came from. We don't fudge the data.
GLP-1 + WEIGHT-LOSS MEDICATION TRACKING
Built-in support for tracking semaglutide, tirzepatide, naltrexone-bupropion, phentermine, and more. See your dose-in-system over time, log side effects, and correlate with weight changes. (Macroline does not provide medical advice.)
APPLE HEALTH INTEGRATION
Sync your weight to and from Apple Health automatically. Your data stays yours.
CONNECT YOUR AI ASSISTANT
Macroline ships with an MCP server, so power users can connect Claude or other AI tools to log meals, query their diary, and ask "how much protein have I had this week?" by voice from their AI assistant.
NO DIET SHAME
No streak pressure. No fasting nudges. No "you ate too much" messages.
Tracking is for awareness — what you do with that awareness is up to you.

Macroline 1.3.3:
BRAND-NEW LOOK
The app now defaults to "Macroline Bright" - a warm, light theme matching our website (we were navy/blue before). New app icon too. Please tell us how the bright theme feels in daylight and at night. You can switch themes under More, then Appearance.
GLP-1 SUPPORT (Mounjaro / Zepbound / Ozempic / Wegovy users)
Brand new. Add your medication under the Meds tab to see:
- A "dose in system" estimate plus schedule
- A protein floor on your goals (protein protects muscle while a GLP-1 curbs appetite)
- Optional symptom logging and tolerance tags on foods
If you are on a GLP-1, add yours and check the dose card and protein guidance. Reminder: this is for awareness, not medical advice.
LIFESTYLE GOALS CALCULATOR
Under More, then Goals, then Lifestyle: enter height/age/activity and it estimates your calorie and macro targets, showing the full math. Run the calculator and confirm the header and inputs look right on your device.
REBUILT BARCODE SCANNER
Completely rewritten. Tap the plus button, then Scan. You now get a proper overlay with a Cancel button, flashlight, and an "Enter barcode manually" fallback. PLEASE TEST: scan a few real grocery barcodes and confirm they are detected and pull up the right food. (This was just fixed - your feedback here is most valuable.)
DESCRIBE A MEAL
Tap the plus button, then Describe: type a meal in plain English ("chicken bowl with rice and guac") and the AI logs it. Confirm the calorie and macro totals look reasonable, not wildly off.
POLISH
Every pop-up sheet (log water, weight, exercise, food details) was rebuilt to be consistent and keyboard-friendly. The Lifestyle screen no longer tucks under the status bar.
Known issue: occasionally Describe or Search matches a close-but-not-exact food - just tap to pick the right one. Flag anything that looks wrong!
