Macronaut - Macro Tracker

Macronaut is a macro tracker for people who train seriously and are tired of apps that nag, guess, or gamify.

Most trackers put a formula in front of you, produce a calorie number, and then leave you to wonder why the scale disagrees. Macronaut starts with the same estimate everyone else does — then stops trusting it. It watches what you actually log and how your weight actually trends, and adjusts your targets to fit the body in front of it. When there isn't enough data yet to say something useful, it says so.

TARGETS THAT LEARN
Your calorie target is checked against reality every week. Macronaut compares what you logged against how your trend weight moved, works out what you are really burning, and offers an updated target. You see the numbers behind it and decide whether to accept — it never changes anything behind your back.

TREND WEIGHT, NOT SCALE NOISE
Daily weight swings by a kilo for reasons that have nothing to do with fat: water, salt, sleep, time of day. Macronaut smooths your weigh-ins into a trend line so you can see the actual direction and rate per week, instead of reacting to noise.

SCAN ANYTHING
Point the camera at a barcode for an instant match. When a product isn't in any database, photograph the nutrition label and the app reads the table directly, then saves it to your own library so next time it's one tap.

RINGS AND DIARY
Calories, protein, carbs and fat as one set of nested rings, with everything you've eaten, everything left, and your goal in the middle. A full diary, a seven-day view, and a calendar of every day you tracked.

YOUR KITCHEN
Bulk-scan your groceries into a pantry. Schedule meal preps across the week with portions planned per day. Get a grocery list built from what you're missing. Nothing else in this category joins these up.

AI COACH
Ask what to cook with what's already in the pantry. Get a read on your week's eating. Ask why a target changed. Choose the tone you want to be spoken to in — encouraging, blunt, or gentle.

VITAMINS AND MINERALS
See your intake of 23 essential vitamins and minerals against daily reference values, with what's running low called out. Estimated from what you logged, and honest about the estimate.

FREE, AND WHAT ISN'T
Scanning, logging, rings, trends, diary, weight, water, pantry, meal prep and grocery lists are free and stay free. The features that call an AI model run on credits, because those calls cost real money — every account starts with a balance and earns more through use. PRO lifts the limits for €4.99 a month or €29.99 a year.

PRIVACY
No advertising SDKs. No third-party analytics. No selling your food or health data — not now, not later. Delete your account from inside the app and everything goes immediately, with no copy kept in reserve.
