Carbon Diet Coach alternative
Carbon is priced like a coach because it is trying to be one. Corvex is priced like a tracker because that is all it is. The search query mixes them. Your week will not.

Verdict
Keep Carbon if weekly check-ins and a coach-shaped algorithm are the product you are buying. Choose Corvex if you want to log food and weight without paying for coaching you will not attend.
Best for: People who will not use weekly check-ins and still need a log.

What Carbon sells, in its own numbers
JoinCarbon’s pricing page (checked 16 August 2026) lists $11.99 a month, $59.99 for six months, and $99.99 a year, with a 7-day trial. That is in the same band as MacroFactor, which is not a coincidence: both are selling adaptive coaching rather than a free diary with a pretty icon.
Weekly check-ins are the ritual. You are supposed to show up. If that accountability is why Carbon works, deleting it for a quieter app is how people “go off plan” and then blame the replacement. Believe the feature list.
Where Carbon is the right tool
You want someone — or something that acts like someone — to set the next calorie and macro block. You like the check-in. You will pay through a cut and a diet break. You are fine without a free tier because the trial was enough to know.
Corvex will not do that job. There is no check-in. There is no coach. There is a diet break glossary page and a deficit-size guide because written explainers are what a tracker company can honestly offer. They are not a programming service.
Where Corvex is the right tool
You already have a target, or you will take a calculator estimate and verify it. You want barcode and recents without a subscription. You have bounced off coaching apps because the check-in became another overdue task. You are on iPhone and you want the home screen to be today’s remaining calories, not a queue.
That is a smaller product. It is also a product you can still use when you are not “on a diet.” Carbon’s year price assumes the coaching relationship is the point. A log you abandon in maintenance was a rental.
MacroFactor sits on the same shelf
If you are shopping Carbon, you are probably also shopping MacroFactor. Both infer or update a plan from your data. Corvex is not the third option in that set. It is the option when you leave that set. The MacroFactor alternative page is the sibling write-up; do not read this as a ranking of coaching apps.
Switching
No Carbon import in v1. Export, keep the file, rebuild staples, cancel from the store or Carbon’s own billing flow according to how you subscribed. Finish a check-in cycle before you leave if you are mid-block — dropping a coach mid-week is a planning problem, not an app-branding problem.
FAQ
Is Carbon Diet Coach free?
There is a 7-day trial on the pricing page we checked. After that you are on a paid plan. There is not a full free coaching product hiding behind the trial.
Does Corvex do weekly check-ins?
No. You log food and weight when you log them. If a missed check-in is the only thing that kept you honest, you will need that structure from a person or from Carbon, not from a quieter diary.
Is Corvex cheaper than Carbon?
The free tier is cheaper than $11.99 a month. Premium, if you want it, is an App Store subscription for history and charts — still a tracker price, not a coach price. Check live listings; these Carbon figures are from 16 August 2026.
Is Corvex on Android?
Not yet. Carbon remains a practical option if you are not on iPhone.
