About this app

Most diet apps are ledgers. You log, they watch, nothing changes.
Macro Trainer is a coach. You log, it thinks, and your plan adapts.

Set a goal — cut, bulk, or recomp — and Macro Trainer builds your calorie and macro targets, programs your training, then pays attention. Stall for two weeks? It notices, explains why, and proposes the adjustment. Fatigue piling up? It suggests the deload before your joints do. Every week you get a report card: what worked, what slipped, and what to do next.

COACHING THAT ADAPTS
• A weekly report card with nutrition and workout scores
• Automatic plateau detection with one-tap macro adjustments
• Deload recommendations when your recovery data says so
• Six coach personalities — from warm and nurturing to zero-excuses — or build your own. Chat runs privately, right on your device.

LOGGING IN SECONDS
• Over a million foods stored on the device — search is instant, even with no signal at the gym or the grocery store
• Barcode and nutrition-label scanning
• Smart recents and planned meals for one-tap repeat logging
• Track full macros, jot quick numbers, or count calories only

PROGRESS YOU CAN READ
• A weight trend that shows the truth: 7-day smoothing, goal projection, and body-composition breakdowns
• Recovery and biometrics: HRV, resting heart rate, sleep, blood pressure, ketones
• Progress photos lined up side by side
• Adherence trends that connect what you did to what happened

TRAINING BUILT IN
• Progressive workout programs with targets that follow your plan
• Set logging designed for the gym floor: big controls, rest timers, volume tracking
• Missed a session? Pick it up where the plan left off.

EVERYWHERE YOU ARE
Native on Android, iPhone, iPad, Mac, Windows, and Linux. Syncs with Health Connect.

TRY IT FOR TWO WEEKS
Download free and use everything for 14 days — long enough for two weekly report cards and a plan that has already adjusted to you. After that, a single purchase unlocks it for good. No subscription, no account, no ads. Everything — including the AI coach — runs on your device, so it's fast, it works offline, and your health data stays exactly where it belongs: with you.

Your goal isn't a diary entry. Bring a coach.

What’s new

Heart rate, respiratory rate, and blood oxygen now appear on the daily biometrics card, in Trends, and as inputs to your recovery score alongside HRV, resting heart rate, and sleep. Health sync settings spell out what each permission powers — every permission is optional, with manual entry as an alternative. Body temperature sync has been removed; we only request health data the app actually uses.
