“I've used countless tracking apps, even as basic as My Fitness Pal.... nothing come close to Carbon. it takes nearly all the guesswork work out and the algorithms are nearly flawless. I've seen much more progress following the app guides in my personal fitness journey, whether it was basic gyming or my transition to my powerlift journey.”

Saved me Apr 11, 2025

“I used to be 250lbs. I was able to cut to about 220 or so on my own. I switched from Loselt (which is also good) to Carbon around that point. Carbon got me down to 177Ibs! Then I was able to use it to reverse, maintain, then gain to 200lbs while resistance training. I love this app it lets you move your weight up and down like clockwork, the support team is great and the features of this app beat the free apps by a mile. This is a coach, it gives recommendations rather than 100% DIY. Love it.”

“I was at a plateau with trying to lose the last 10 pounds. It wasn't until started using this app that I was able to break through my plateau. The calories/macros settings/adjustments they are able to do are what have helped me. While I thought I had it figured out, it took me using this app since it comes with a coach who has made all the difference in the world. I was previously using My Fitness Pal. If you are trying to get through a plateau, I would highly recommend trying this app.”

Fantastic app! Feb 13, 2025

“I struggled to lose weight I gained with perimenopause, but now I see I was massively under eating. Currently I am on 2400kcal and losing 0.4kg per week. These calories allow me to eat plenty of good food, I have energy and I also have so much energy for my workouts. I really love this app! Highly recommend!!! ✨ ❤️”

“.4 away from my current goal! It's been a long and consistent journey. Never bothered worrying about it the app says I'm not compliant as it's simply a tool to help keep on the right track. Ups and downs are part of the journey. Super happy with my success using the app 💪.”

Jason Oberuc

“If you have basic knowledge of nutrition and Carbon, you will never need a nutrition coach again! Thank you @biolayne for creating such a useful tool!”

Makes it easy Apr 16, 2025

“This app is helping me stay accountable and makes it really easy to track and input my macros. Using this app as a coach, weighing my food, and consistent workouts have made it really brainless to drop weight. I won't share my results, but I'm surprised at how good I feel and how my body has responded.”
