About this app

Most fitness 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. Sleep and energy entries help you reflect on recovery. Every week you get
a report card: what worked, what slipped, and what to do next.

COACHING THAT ADAPTS
• Separate coach conversations with saved history and draft recovery
• A weekly report card with nutrition and workout scores
• Automatic plateau detection with one-tap macro adjustments
• Optional deload proposals for you to review before applying
• GLP-1 companion mode with protein-first targets, a dose diary, and
appetite-aware coaching
• Six coach personalities — from warm and nurturing to zero-excuses — or
build your own. Chat runs privately, right on your device.

LOGGING IN SECONDS
• Snap a photo of your plate: your coach names each food and estimates the
portions, you confirm, and it's logged as real servings
• Or just say what you ate, typed or dictated — "two eggs, sourdough toast
with butter, black coffee" — and your coach splits it into foods and
sizes each one for you to check before it's logged
• 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 with 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.

SPEAKS YOUR LANGUAGE
Macro Trainer is at home in 34 languages — the interface, your weekly
report card, and the coach itself. It follows your phone's language, or
whichever one you pick.

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.
