How to track macros on iPhone
On iPhone, track macros by texting Marco in iMessage (or SMS). Describe what you ate; Marco replies with protein, carbs, fat, and calories and keeps a persistent log — no separate macro app required.
iMessage is the interface
Save Marco like any contact. Send meal texts from the lock screen, CarPlay continuity, or your watch-adjacent habits — wherever Messages already is. Replies land in the same thread.
Set goals on the phone you have
Text targets such as calorie or protein goals. Daily summaries reference those targets so you are not hunting settings screens in a fitness app.
- “set my protein goal to 130”
- “set my calorie goal to 2100”
- “macros today?”
iPhone without App Store clutter
If you refuse another health icon, messaging-based tracking is the path. You still get structured history — meals are not trapped only in iCloud chat memory.
Android partners still work
Households are mixed. Marco supports SMS/RCS too, so you are not locked into an iMessage-only tracker.
Frequently asked questions
What is the easiest macro tracker for iPhone?
If you already live in Messages, Marco is among the lowest-friction options: text the meal, read macros in-thread.
Do I need to download Marco from the App Store?
No. Early access works through messaging after you join the waitlist.
Can I track macros offline on iPhone?
Sending the text needs connectivity like any iMessage/SMS. There is no separate offline database UI to maintain.
Ready to track by text?
Join the waitlist for early access. No app to download — once you’re in, you text Marco from the messaging app you already use.
