The macro tracker you'll still be using in March.

Targets that retune themselves every week. Log dinner from a photo, sort out a restaurant menu before you order, run your gym sessions, and raise a dino that grows on every day you show up.

What you get

Five things no other tracker puts in one app.

Every tracker can count a calorie. These are the five that decide whether you keep opening it.

AI FOOD LOGGING

Log a whole meal in one photo.

Snap your plate, say it out loud, or type it. The food gets read and your macros fill themselves in, in about the time it takes to sit down. Barcodes and labels too, and you never have to weigh a thing.

Photo · voice · textBarcode + label scan
EATING OUT

Know what to order before you sit down.

Paste the restaurant's link, or photograph the menu at the table. Every dish gets read, costed and ranked against the day you have actually got left. Still want the burger? It won't hide it from you. It just tells you what it costs.

TRAINING

Your gym sessions, in the same app.

Pick the gym you're actually standing in and Macrosaurus programmes around the kit that's really there. Log your sets as you go, watch every lift climb week on week, and a session keeps your streak alive the same as a clean day of food.

YOUR DINO BUDDY

The reason you'll open it again tomorrow.

Hatch one egg and raise one dino. It bonds and evolves on every day you hit your targets, and when you're stuck you can just ask it what to eat with the day you've got left. It never logs anything behind your back: you tap to confirm, every time.

Hatch, bond & evolveTalk to itDaily Hunt + boss fights

TWELVE SPECIES TO HATCH. ONE IS YOURS.

How it works

Track your macros in three steps. About two minutes.

No spreadsheet, no weighing everything, and no starting again on Monday.

STEP 1

Set your goal

Tell it your height, weight, how active you are and what you are aiming for. You get a starting calorie and protein target, and an egg to look after.

STEP 2

Log food in seconds

Photograph the plate, say it out loud, scan a barcode or paste a restaurant menu link. The calories and macros fill themselves in.

STEP 3

Let it retune weekly

Every week your targets adjust to your real trend weight, with the reason shown. Your dino grows on each day you show up.

Under the hood

Your calories and macros retune themselves every week from your real trend weight, and you can always see exactly why they moved.

Free tool

Free macro and calorie calculator.

Work out a starting calorie and macro target in ten seconds. It uses the Mifflin-St Jeor equation for your daily energy use, then sets protein from your body weight and splits the rest between carbs and fat.

  • Metric or imperial, no sign-up
  • Protein set per kg of body weight
  • A starting point: the app retunes it weekly from your real results

Who it's for

A macro tracker for fat loss, muscle gain and everything between.

Losing fat without misery

Sensible targets from your real trend weight, a protein goal that protects muscle, and no being told to eat 1,200 calories. Every adjustment comes with its reason.

Building muscle

Track protein, calories and your lifts in the same app, and watch your weekly trend so a surplus stays a surplus and not a binge.

Eating out and ordering in

Paste a menu link or photograph the menu and see every dish ranked against what you have left today, from restaurants to delivery apps.

People who quit trackers

Logging from a photo takes seconds, a training session keeps your streak alive, and a dino that grows when you show up gives you a reason to open it tomorrow.

The game

Meet the twelve dinos you can hatch.

Pick the species you like the look of, name it, and look after it by looking after yourself. It grows on the days you show up, and it never logs anything behind your back: you tap to confirm, every time.

From the founder

I tried every macro tracker going, and quit all of them by about week three. Accurate enough, maybe, but a chore to open, and no help at all the moment I sat down in a restaurant or walked into a gym. So I built the one I actually wanted to use, and I've used it every day since. It's early days and I'm building it in the open: free to start, no card, no hype. If you give it a go, tell me what you think.

Questions

Good to know

Is it really free?+
Yes, and not the kind of free that stops working in a fortnight. Core tracking, the adaptive engine, weekly check-ins, gym training and the entire game are free forever, with no card to start. Premium adds food quality scoring, unlimited AI logging, the full recipe library and body-fat scans.
Is it actually science-based?+
Yes. Your targets retune each week from your real trend weight using research-backed methods, and every change comes with the reason it happened. No black box, no mystery numbers, no being told to eat 1,200 calories.
How is it different from other trackers?+
You still get the adaptive science and quick AI logging you'd expect, plus three things most trackers skip: it reads a restaurant menu and ranks it against the day you have left, it runs your gym sessions in the same app, and it has a game that genuinely makes you want to log. And it's built for the UK. Your units and your supermarket, not just the States.
Can it help me order when I'm eating out?+
Yes. Paste the restaurant's link or photograph the menu at the table. Macrosaurus reads every dish, estimates the macros, and ranks the menu three ways: what fits the rest of your day, most protein, or lightest, and switching between them is instant. It never hides a dish for being too big: it tells you what it would cost and leaves the choice to you.
Does it track training as well as food?+
Yes. Pick the gym you're actually standing in and Macrosaurus programmes around the kit that's there. Log your sets as you go, follow each lift's progression, and a training session keeps your streak alive the same as a clean day of food. Training logging is free and always will be.
Can I import recipes from TikTok, Instagram or YouTube?+
Yes. Share a cooking video straight to Macrosaurus from TikTok, Instagram or YouTube, or paste the link. We pull out the ingredients and method, work the macros out to the gram, and save it to your library sorted by what fits your day, so you never have to pause and rewind a 30-second video again.
Do I have to weigh my food?+
No. Scan a barcode, snap the label, or photograph the plate and let AI estimate it. Weighing is optional if you want extra precision.
What are macros, and how many do I need?+
Macros are the three nutrients that make up your calories: protein, carbohydrate and fat. Protein is the one to anchor on, and a common evidence-based range for people who train is about 1.6 to 2.2 g per kg of body weight. The free macro calculator on this page gives you a starting estimate, and the app then retunes it every week.
How does an adaptive macro tracker work?+
Instead of a fixed number you set once, Macrosaurus compares what you are logging with your real trend weight, which smooths out daily water-weight noise. If your weight is moving faster or slower than your goal, your calories and macros are nudged to match, and the reason for each change is shown.
Is Macrosaurus a calorie counter too?+
Yes. It counts calories and all three macros, plus fibre, and shows what you have left for the day. It also helps you work out what to eat with those calories, from a restaurant menu or a saved recipe.
Does it work on iPhone and Android?+
Macrosaurus runs in your phone's browser and can be added to your home screen so it opens like an app, on both iPhone and Android. There is nothing to download from a store, and your data follows your account.
