macroBody learns how your body actually burns energy — and rewrites your calories and macros every week. Snap meals with AI, log a lazy day by feel, finish any day in one tap.

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.
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.
USDA FoodData Central, Open Food Facts and FatSecret — blended and re-ranked for relevance, region and data quality, so the food you mean shows up first. Packaged? Just scan the barcode.
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.
Try it — tap the − and + buttons.
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.
You hit every target for the day.
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.
You can adjust it later if you need to.
Water, salt, sleep, a late dinner. Daily weigh-ins bounce around for reasons that have nothing to do with fat.
macroBody smooths every weigh-in into a trend line — the real direction, minus the noise. No more panicking over a one-day blip.
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.
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.
TDEE = avg intake − Δ trend × 7700 ÷ days

XP is recalculated on the server from your real history, so it can't be gamed. Not your thing? One toggle hides it.
The Mifflin–St Jeor equation estimates what your body spends at rest.
10·80 + 6.25·180 − 5·30 + 5
1 780 kcal
Your activity level scales it into a starting total daily energy expenditure.
1 780 × 1.55
2 759 kcal
Your pace becomes a daily delta, using 7 700 kcal ≈ 1 kg.
2 759 − 0.25 × 7 700 ÷ 7
2 484 kcal
Protein follows bodyweight and training, fat your diet style, carbs fill the rest.
176·4 + 72·9 + 283·4 = 2 484
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.
Scan any packaged product and pull its nutrition straight from the global catalog.
Fiber, sugars, fat subtypes, omega-3/6 and minerals — per food and per day.
A smoothed line through the noise, so a salty dinner never ruins your week.
Balanced, low-fat, low-carb or keto — and high and low days across the week.

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