Most apps hand you a number on day one and never look again. macroBody treats your body like the experiment it is — every meal and every weigh-in teaches it something, and your targets move with what it learns.

07:30Breakfast

Snap the plate.
We'll do the math.

Point your camera at any meal. macroBody's AI — built on the latest vision models and fine-tuned in-house — names every food, estimates each portion and drops a fully macro'd entry into your log. You just confirm.

Your recipe,
your way — every time.

Save a meal once. Then log it with a bit more rice and a little less oil — without touching the saved recipe, and without a near-duplicate “Chicken bowl (2)” cluttering your list.

  • Nudge any single ingredient as you log
  • Or scale the whole bowl — every ingredient follows
  • Logged as its real foods, so macros and micros stay exact

9 pm. 552 kcal left. Fridge open. Here's dinner — built from food you actually eat.

The hardest meal of a macro target is the last one. Tap Complete my day and macroBody works out exactly what still fits — then builds a coherent plate from your recipes and the meals you've really eaten, portioned to the gram.

  • One protein, one carb, one fat — never whey next to a sausage
  • If the day can't be closed cleanly, it tells you honestly
  • One tap logs the whole plate

23:00Lazy Add

Didn't track today? Some days you just eat. Don't lose the day — log it by feel.

Tell macroBody how today compared to a usual day. It scales your own baseline into an honest estimate — no weighing, no searching. Saved as an estimate, the coach trusts it 25% less, so your model stays clean.

  • Scales your targets or your recent days — never a generic guess
  • Two seconds, five choices
  • Flagged as an estimate in your weekly check-in

SundayWeekly check-in

Your scale lies
a little every day.

Water, salt, sleep, a late dinner. Daily weigh-ins bounce around for reasons that have nothing to do with fat.

Your trend
doesn't.

macroBody smooths every weigh-in into a trend line — the real direction, minus the noise. No more panicking over a one-day blip.

Then it measures
your burn.

What you logged, versus how your trend actually moved, reveals what you really burn. Not a textbook formula — you. The band tightens as it learns.

And moves
your target.

Once a week you see exactly what changed and why. Accept it, or don't — between check-ins your target stays frozen, so you never chase a wobbling number.

The Mifflin–St Jeor equation estimates what your body spends at rest.

Activity → TDEE

Your activity level scales it into a starting total daily energy expenditure.

Goal → calories

Your pace becomes a daily delta, using 7 700 kcal ≈ 1 kg.

Split into macros

Protein follows bodyweight and training, fat your diet style, carbs fill the rest.

176·4 + 72·9 + 283·4 = 2 484

Then the loop closes.

After about ten logged days and a few weigh-ins, macroBody stops trusting the textbook and starts trusting you — measuring your real expenditure and rewriting every target. That's the difference between a calculator and a coach.

Questions, answered.

How is macroBody more accurate than a TDEE calculator?

A calculator gives you one static estimate and walks away. macroBody starts there, then measures your real expenditure from how your trend weight responds to what you log — and recalculates your target every week.

Do I have to weigh and log perfectly?

No. Trend-weight smoothing absorbs daily fluctuations, quick estimates are down-weighted, and the weekly check-in lets you flag messy days so they don't distort the math.

What is “Complete my day”?

A one-tap answer to “what do I eat now?”. macroBody takes what's left of your macros and suggests a coherent plate that closes the gap — built from your own recipes and the meals you've actually eaten.

How does leveling up work?

You earn XP for logging a day, weighing in, hitting your targets and keeping a streak — and every weekly check-in is a guaranteed level. XP is recalculated on the server from your real history, so it can't be gamed.

Is my data private?

Your account is yours. Logs sync securely so you can switch devices, and we never sell your data. See the privacy policy.

What do I get for free?

A 7-day free trial of everything, a complimentary 24-hour logging window for every new account, and two free AI photo recognitions.
