Tired of scanning every barcode? A Carbon Diet Coach alternative that skips logging.
Carbon Diet Coach is a serious macro-coaching tracker — if you're willing to log everything you eat. Here is what it does well, where reviewers get stuck, and a different way to hit the same numbers.
Updated September 2026
Carbon Diet Coach — sold on the App Store as Carbon: Macro Coach & Tracker — is built around a weekly check-in: you log your weight and your food, and the app recalibrates your calorie and macro targets from that trend. It was built with input from sports nutritionist Layne Norton and RD Keith Kraker, and it has a loyal following among people who lift and track seriously.
This page sticks to what Carbon itself publishes and what its own reviewers say, then explains what Macro Recipe does the same, what it does differently, and what it does not do. It is written by the team behind Macro Recipe, so read it with that in mind.
What Carbon Diet Coach does well
Its core idea is a real coaching loop, not a static calculator: targets adjust automatically week to week from your logged weight and food, rather than staying fixed until you manually recompute them.
It is built and endorsed by a recognized name in sports nutrition, which carries real weight with a strength-training audience, and it syncs with Apple Health and scans barcodes for fast logging in supported regions.
It is well rated: 4.8 out of 5 on roughly 8,100 ratings on the US App Store, 4.4 on the sample seen on the French store.
Who it is for
Carbon fits someone who already logs food and wants the app to think about the numbers for them — a lifter chasing a physique goal who is willing to scan barcodes and weigh in on a schedule, and who mostly eats US, Canadian, UK or Australian packaged products the barcode database actually covers.
It is a tracker for people who eat first and account for it after. If the daily habit is scanning what you already ate rather than deciding what to cook, Carbon is built for that.
Where it stops
The most repeated complaint is price with no way to try first: "This app is the market's most expensive" — one FR App Store reviewer, noting there is no free trial.
The official pricing confirms it: $11.99/month, $59.99 for 6 months, $99.99/year, no free tier.
Cancel and your history locks: the same reviewer describes needing to pay again — "minimum €13" — just to see past logs.
Outside North America, the barcode scanner runs thin. A UK reviewer said it "couldn't find" common UK products like Heinz baked beans, and called the app "more suited to foods in the American market".
Carbon's own developer reply confirms the food database "currently supports only US, Canada, UK, and Australia" — France, Belgium, Switzerland and Québec are not on that list.
What Macro Recipe does the same
Like Carbon, the goal is hitting an estimated calorie and protein target — you set cut, maintenance or muscle gain, and the app works toward it. Diets and allergies are respected rather than left for you to check.
Both are paid apps: Macro Recipe is not offering a free lunch that Carbon withholds. Your first menu is free and there is a 3-day trial, then it is 9.99 €/month or 69.99 €/year — Carbon's is $11.99/month or $99.99/year with no trial.
What it does differently
Macro Recipe does not ask you to log anything. Instead of scanning what you already ate, you get a weekly menu of real recipes built to land near your estimated target, so the number comes out right because of what gets cooked — not because of what gets scanned after the fact.
Everything in the menu becomes one grocery list, with an estimated cost in your own currency. Carbon has no grocery list and no budget feature at all; it only tells you what you already bought and ate.
There is no barcode database to run out of coverage. A recipe built for France or Québec is written for the ingredients sold there, so the gap Carbon's own developer reply admits for those markets simply does not apply.
What it does not do
No barcode scanner, no daily food log, no weekly coaching check-in, and no Apple Health sync. Macro Recipe is not a tracker and is not trying to out-track Carbon — if scanning restaurant meals and off-plan snacks is what you want, Carbon does that job and Macro Recipe does not.
It does not keep a history of everything you personally ate over months, the way a logger does; it plans the week ahead rather than recording the one behind you.
It is on iPhone today, and it is a paid subscription like Carbon — first menu free, 3-day trial, then 9.99 €/month or 69.99 €/year.
Switching in practice: what to keep, how the first week looks
Keep the habit Carbon gave you of thinking in a weekly window rather than judging one meal in isolation — that instinct carries over directly. Keep your target macros or goal (cut, maintain, gain) in mind when you set up your profile.
You will not carry over your logged history — Carbon has no export, and the two apps work differently enough that a food log would not map onto a recipe menu anyway. What you bring instead is your diet, your allergies and the goal you were training toward.
A first week looks like this: set your goal and diet, get a free first menu built around it, check the grocery list and its estimated cost, then cook. There is nothing to scan and nothing to log at the end of the day — the target was built into what you cooked.
Price, side by side
Carbon: $11.99/month, $59.99 for 6 months (about $9.99/mo equivalent), $99.99/year (about $8.33/mo equivalent), no free trial.
Macro Recipe: first menu free, then a 3-day trial, then 9.99 €/month or 69.99 €/year — an estimated grocery cost is included in every week, which Carbon does not offer at any price.
What three days of a weekly menu look like
An indicative example for someone aiming at roughly 1,900 kcal and 140 g of protein a day. Estimated figures; your own menu is built from your profile, your goal and your budget.
Frequently asked questions
Is there a free Carbon Diet Coach alternative?
Carbon has no free tier and no free trial. Macro Recipe gives you one free first menu with no card required, then a 3-day trial before the paid subscription starts.
Why is Carbon Diet Coach so expensive?
Its official pricing is $11.99/month or $99.99/year with no free trial. Reviewers on the App Store have flagged the lack of a trial as the app's main friction point before you can judge if it's worth it.
Does Carbon Diet Coach work outside the US?
Its barcode food database is confirmed by Carbon's own developer reply to only cover the US, Canada, UK and Australia. French, Belgian, Swiss and Québécois users have reported the scanner missing everyday local products.
What happens to my Carbon Diet Coach history if I cancel?
One App Store reviewer reports that history locks after cancellation and that reopening it required paying again. Macro Recipe does not depend on a logging history at all — each week's menu is built fresh from your profile.
Do I have to log my food with Macro Recipe like with Carbon?
No. Macro Recipe builds the week's menu to land near your estimated calorie and protein target before you cook, so there is nothing to scan or log afterward. If you want to track individual meals separately, that is what Carbon is built for.
