Most diet apps are ledgers.
Macro Trainer is a coach.
Set a goal — cut, bulk, or recomp. Log your food in seconds. Then get coaching that actually adapts: weekly report cards, plateau fixes, deload weeks, refeed days — until the mirror agrees with the plan.
Also on Mac, Windows, and Linux — see all platforms.
Log it in three seconds
Logging you'll actually keep doing. The entire food database lives on your device, so search is instant — in the gym basement, on a plane, anywhere.
- Over 1 million foods: Search as fast as you can type, with zero loading spinners.
- Point and scan: Barcode scanning for packaged food, and a label scanner that reads nutrition facts panels for everything else.
- One-tap repeats: Smart recents and planned meals put your usual breakfast one tap away.
- Your level of detail: Full macros, quick-macro jots, or just calories — the coach adapts to whatever you track.
A coach that pays attention
You log, it thinks, your plan adapts. Macro Trainer watches your weight trend, training, and recovery — then acts, so you're never guessing what to do next.
- Weekly report card: Nutrition and workout scores with plain-language insights on what worked and what to change.
- Plateau fixes: Two flat weeks? It notices, explains why, and proposes the macro adjustment — you approve with a tap.
- Deloads & refeeds: When fatigue piles up or a cut needs a break, your plan says so before your joints do.
- Supportive check-ins: Stop logging and your coach reaches out with encouragement, not a guilt trip.
Ask it anything Beta
Chat with your coach about plateaus, fatigue, restaurant menus, or what to cook tonight. Replies are generated entirely on your device — nothing you say ever leaves it.
- Knows your plan, your logs, and your trend
- Answers in your coach's voice, not chatbot-speak
- Private by design — works with no connection at all
Train with intent
Nutrition is half the plan. Macro Trainer programs the other half — and pairs the two, so your fuel matches your training phase.
- Popular templates: Upper/lower splits, push-pull-legs, full-body, and more — paired with nutrition styles from traditional bodybuilder to keto and carnivore.
- Built for the gym floor: Big controls, rest timers, and set targets that follow your progression.
- Life happens: Miss a session and the plan offers it back — no guilt, no gaps in your progress.
- Volume & strength trends: Watch working weight and weekly volume climb over the block.
Progress you can actually read
The scale lies daily. Your trend doesn't. Macro Trainer turns noisy weigh-ins into a clear line — and connects what you did to what happened.
- The trend, not the noise: 7-day smoothing and a projection line that shows when you'll reach your goal at the current pace.
- Body composition: Lean mass, body fat, and water — one tap away when you want the detail.
- Progress photos: Front, side, and back — lined up side-by-side so change you can't feel becomes change you can see.
- Light or dark: Every chart is designed to be legible in both. This one's dark mode.
Your body, in numbers
Recovery is where progress actually happens. Track the signals that matter and watch them move as your fitness builds.
- Recovery signals: Resting heart rate, HRV, and sleep — synced from Apple Health or Health Connect, or logged by hand.
- Deeper biometrics: Blood pressure, blood glucose, and ketones for those who go further.
- Adherence trends: See how consistently you've hit your targets — and how that lines up with results.
- Daily biofeedback: Energy, hunger, and sleep-quality check-ins keep your coach honest about recovery.
Make it yours
No two goals — or personalities — are the same. Macro Trainer bends to yours.
- Six coaches, one you: From warm and nurturing to zero-excuses. Switch anytime; your plan carries over.
- Or invent your own: Describe any personality you can imagine — a stoic philosopher, a 1920s strongman, your favorite fictional captain — and coach with it.
- Your Today screen: Reorder or hide every card on the dashboard. Your day, your layout.
- Your diet, your rules: Flexible, traditional bodybuilder, keto, carnivore — or skip macros entirely and track calories only.
Meet your coaches
Six personalities, one job: getting you to your goal. Pick the voice that works on you — or build your own. Every coach runs privately on your device, and you can switch anytime.
Coach Sam
A former small-town family doctor from the Blue Ridge mountains. Whole foods, protein-forward plates, and front-porch honesty — friendly to low-carb and carnivore eaters, without the dogma.
Coach Mark
A former blue-collar worker turned powerlifter who discovered fitness late in life. He knows what it's like to juggle a 60-hour work week, so he refuses to accept lazy excuses.
Coach Eisley
A biology and chemical engineering grad who turns hard science into warm, practical coaching. Eisley loves books, coffee, and holding you accountable — with data to back it up.
Coach Anne
A busy working mom of two who spent her 20s battling yo-yo diets. She focuses on metabolic restoration and flexible fueling because you can't live off chicken and broccoli forever.
Coach Naz
A retired physical therapist and masters powerlifter who believes it's never too late to build strength. Muscle, bone, mobility, and healthspan for the 50+ crowd.
Coach Theo
A former collegiate runner and Ironman finisher who treats food as fuel. For runners, cyclists, and athletes who train hard and need to eat like it.
