Down-to-earth & whole-food
A former small-town family doctor. Whole foods, protein-forward plates, and front-porch honesty — friendly to low-carb and carnivore eaters, without the dogma.
Now on the App Store and Google Play
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.
Free for 14 days on iPhone, iPad, Android, and Mac. Linux is free; the Windows Store release is pending — see all platforms.
Make logging a habit
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.
- Snap your plate: your coach names each food in the photo and sizes the portions; you check the list, then log. Photo recognition happens entirely on your device.
- Describe a meal: type what you ate, then check the matched foods and portions before logging.
- 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.
Photo logging needs optional AI setup and model downloads. Support and download sizes depend on your device — see AI requirements. Optional backups can include photos.
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, without sending your conversation to an AI service.
Enable AI features and download the models before chatting. Low-memory phones may be slower; tracking and regular coaching tools work without chat — check your device.
- Knows your plan, your logs, and your trend
- Answers in your coach's voice, not chatbot-speak
- Private by design — works offline after setup

Weight's been stuck for two weeks. What do we do?
Let's look at your trend and how consistently you've hit your targets. If a smaller daily calorie target fits your plan and is safe, I can propose one for you to review before applying it.
Review daily target adjustment
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.

Good questions
What happens after the 14 days?
On iPhone, iPad, Android, and Mac, new logging and coaching wait behind the one-time purchase. Everything you already logged stays readable — it's your data, and we're not going to hold it hostage to make a point.
I bought it on my iPhone. Does that cover my Android tablet?
The purchase lives with your store account, so an App Store purchase covers iPhone, iPad, and Mac, and a Google Play purchase covers Android. It doesn't cross between stores — that's how the stores work, not a stance we're taking. If you've bought it once and need it on the other side, email [email protected] with your receipt and we'll send you a code.
I bought Macro Trainer before the trial existed.
It stays yours. The app recognises earlier purchases automatically. If yours slips through — a fresh install with no backup can — email [email protected] and we'll fix it the same day.
Why is the Linux build free?
Little Theta LLC offers Linux builds free as a contribution to the ecosystem. Install instructions are here.
