Macronomics

Hit your numbers. Both of them.

Every app tracks your macros. Macronomics also tracks what they cost, pricing every meal at real shelf prices so you hit your protein and your budget.

Free while it’s in beta. Sign up now and it stays free for you, forever.

The gap

Every app counts your protein. None of them count your money.

Both numbers describe the same seven days of eating. Tracking the first one is solved. The second decides whether you are still eating like this in March.

What your tracker sees

180g protein a day

Logged, charted, congratulated. Every app has this.

What it never sees

$94for the week

What it cost to hit that number. No app has ever asked.

The 180 g and $94 are an example week, to show the shape of the problem.

Where it goes

Your grocery bill creeps up, and you can’t say why.

Nothing in the trolley looks expensive on its own. A protein shake, a yoghurt pouch, the nicer juice because it’s only a bit more. Each one is small enough to miss, and the total climbs anyway. Macronomics prices everything you eat, so you can see exactly where the money goes, and what the same food costs for less.

Full shelf prices at a major Australian supermarket, read between 14 and 24 September 2026. Each portion is priced as its share of the pack it comes from; a pouch, a carton and a bottle are the whole pack.

Free during the beta

Free now. Free forever, if you join now.

Macronomics is free while it’s in beta. It won’t stay that way: once enough people are using it, new accounts will pay $8 a month. Everyone who signs up before then keeps it free, for good.

New accounts after the beta: $8 a month. Yours: nothing, for as long as Macronomics runs.

$40a week

Even at full price21×overwhat it would cost, every month
Back in a year$2,080and the app costs you nothing

Saving $40 a week is 21 times what Macronomics will cost new accounts every month, and $2,080 back in a year.

Arithmetic, not a promise. What you save depends entirely on what you eat and buy now; the slider is yours to set, and the swaps above are the worked example. The founding-member promise is in the terms.

How it works

Plan it, price it, log it. Dollars beside every macro.

  1. 01

    Plan the week

    Pick the meals, set the serves. The plan prices itself as you build it, so you find out a recipe is expensive before you shop for it.

  2. 02

    Price the shop

    Whole packs, not pro-rata grams, rounded once across the whole week, so the list adds up at the register.

  3. 03

    Log it in seconds

    Breakfast, lunch, dinner, snacks. Macros and dollars on the same line, from a catalogue where every panel has been checked.

  4. 04

    Swap, and see the difference

    Which meals cost most per gram of protein, and exactly what one swap saves. Before you buy it, not after.

The difference

Other trackers count. This one does the sums.

Costed nutrition

The number your supermarket won’t show you.

Every shelf label carries a unit price: dollars per 100 g of product. What you want is dollars per 100 g of protein. Here it is, live from the catalogue.

  1. 1RSPCA Approved Chicken Drumsticks2kg · $8.00 ($4.00/ 1kg)$2.27/100 g protein
  2. 2Cocktail Frankfurts 400g400g · $1.99$3.57/100 g protein
  3. 385% Lower Carb High Protein Loaf500g · $5.40 ($1.08 per 100g)$3.88/100 g protein
  4. 4Firm Tofu 450g450g · $2.59 · panel carries a caveat$3.92/100 g protein
  5. 5Complete Protein Bread500g · $7.00 ($1.40 per 100g)$4.23/100 g protein
  6. 6Basa Fillets1kg · $7.00 ($7.00 per 1kg)$4.49/100 g protein

Prices read 25 September 2026, full shelf price. The cheapest of each kind of protein food, at least 10 g of protein per 100 g. Staples like pasta and oats are left out: they are cheap per gram of protein only because you’d eat most of a bag to get it.

My weekly shop

Before
$250
Now
$120

$130 a week back

My own shop, over the last year. A description of what happened to me, not a promise about you.

Why it exists

I built it because my tracker cheered while my bank balance fell.

Three or four trips a week, no plan, and an app that congratulated me on hitting 180 g of protein while I quietly went backwards. It knew everything about my food and nothing about my money.

So I built this for myself first: one shop, every meal for the week planned and costed before I leave the house. What you save depends entirely on what you eat now and where you buy it.

Joey, Sydney

The promise

We quote you the worst case.

A planner that says $120 and charges you $148 isn’t a bug, it’s a liar, and you only have to catch it once. So every number is deliberately pessimistic.

Full shelf price, always

Specials change weekly, and nothing here pretends to know whether yours is on.

Whole packs

You can’t buy 340 g of a 500 g block, so the list never prices it that way.

Every price dated

Each product shows the day its price was read, and says so when that is getting old.

The last list I saved came to $128.75 across fourteen products. The register agreed, because the app had already assumed the worst about every one of them.

Questions

Straight answers.

What does it cost?

Nothing while Macronomics is in beta. When the beta ends, new accounts will pay $8 a month for the whole app. If you sign up before then, you never pay: founding members keep it free for as long as Macronomics runs.

When does the free beta end?

When enough people are using it to justify charging. There is no date yet, and it will be announced here ahead of time. Nothing changes for anyone who already has an account.

Where do the prices come from?

Australian supermarket shelves, at full shelf price, each with the date it was read. Australia only: the whole thing is priced in one country’s supermarkets, and more of them are being added.

Why ignore specials?

Because they change weekly and nothing here can know whether yours is on. A plan built on this week’s half-price chicken is wrong next week. Full shelf price is the worst case, so the real bill only ever comes in under it.

What if my food isn’t in the catalogue?

Ask for it from inside the app and it gets added. The catalogue is curated, and nobody can upload a product. That is why the numbers are worth trusting, and also why it is not every item in the store yet.

Is it only for people who lift?

No. It is for anyone with a target and a budget: a protein number, a calorie number, or just a week that has to cost less than it does now.

Who sees my food log?

You. Your diary, plans and body figures are yours alone, never sold and never shared. The privacy page says exactly what is stored.

Know what your week costs before you shop for it.

It’s free while it’s in beta, and free forever for everyone who joins before that ends. Sign in with an email link or Google and see what a day of your food costs.
