It’s worth every cent. At last you don’t have to worry if you’re doing it right—carbon and the incredible team behind it has got your back. If you actually measure and log everything you eat and hit your target macros for 3 months, you’ll see so much progress. The app adjusts to your actual progress and adherence. I find it’s coaching to be accurate, not generic. I’ve recommended this to about 5 or 6 people who have started using it—each to great success. ### 5/5 — My coach *2026-08-10, version 2.77.6010* Coach was really good, but it updated and now it’s PERFECT. ### 5/5 — Best app for tracking macros *2026-08-09, version 2.76.5966* Great recipe builder and easy to adjust everything! ### 5/5 — Life changing *2026-08-09, version 2.76.5966* Lifted for years without adding muscle, using Carbon accomplished the goal. Best support experience of any product in my entire life. ### 5/5 — The driver of my diet consistency *2026-08-09, version 2.76.5966* I’ve struggled with maintaining and manipulating my body composition for most of my life until I started using carbon. The app is easy to use, and I just track everything I eat even if I go over my calorie budget, because I can trust I can try harder next week and the AI will take care of me. Just get the app and stop overthinking it. ### 4/5 — A sweet app *2026-08-08, version 2.76.5966* I’ve been using Carbon for more than a year. My man uses carbon too. I love being able to make a recipe and send him the link so he has accurate macros, too. Their customer service is fantastic. Every time I use the message feature, the responses are prompt and helpful. Thank you Layne and the Carbon team! ### 5/5 — Great *2026-08-06, version 2.76.5966* Great ### 5/5 — Perfect calorie tracking app *2026-08-05, version 2.76.5966* Has all the features and math I want and need ### 5/5 — Best Tracker *2026-08-02, version 2.76.5966* I’ve used this app since 2020 and I it has proven time and time again why it’s the superior tracking app. Improvements have been made, and the coach does a great job calculating macros for your goals as long as you are HONEST with your data. Way better than anything else on the market. ### 5/5 — Great support *2026-08-02, version 2.76.5966* John has been addressing my concerns and questions in prompt manner. I like the app and trusting it. Using it only for a week, but I see great value. Using currently a reverse diet program after a four months strict diet, prior joining the Carbon. ### 5/5 — Mi coach favorito!! *2026-08-01, version 2.76.5966* Como no amarlo !!Y lo vuelvo a actualizar años despues los sigo amanso carborn el mejor !!! ### 5/5 — There just isn’t another option *2026-08-01, version 2.76.5966* With the backing of Norton and his team, this app is second to none. It is user-friendly and adjust appropriately. This app is getting myself and my wife back on track to be the parents. My children deserve. ### 5/5 — Science based diet *2026-08-01, version 2.76.5966* Most accurate BMR calculation out there. If you’re after precision and evidence based tracking, in my opinion, there is no better. ### 5/5 — Great tracker app *2026-07-31, version 2.76.5966* Smart tracker. I like that you can adjust each days goal to meet a weekly target. ### 5/5 — Simple and Easy *2026-07-30, version 2.76.5966* This is the best app to help achieve your fitness goals. Been a member for a few years and it never fails me. The lay out is clear and simple. I love it! ### 5/5 — Amazing *2026-07-26, version 2.76.5930* As a trainer I use it for myself and my clients. This app is amazing and everything I need to keep my dieting/building phases healthy and flexible. ### 5/5 — Major weight loss *2026-07-26, version 2.76.5930* Three years ago I heard about Carbon and I took a chance. Now I’m down around 190. Best decision I’ve ever made ### 5/5 — Excellent *2026-07-26, version 2.76.5930* Easily the best macro coach/tracker I have used. ### 5/5 — Forever with Carbon *2026-07-23, version 2.76.5930* Best calorie tracking App out there! I will use this app forever! ### 4/5 — If your serious *2026-07-21, version 2.76.5891* Lose / again / Maintain. Do it all with Carbon ## Most critical reviews (10 lowest-rated) ### 1/5 — Bar code scanner not work *2026-04-06, version 2.74.4732* Be great app but bar code scanner and label scanner works 50% of the time. Contacted support who can’t resolve the issue or offer a refund I now must go through Apple ### 1/5 — NO ACCOUNTABILITY *2026-03-06, version 2.74.4732* The business owner won’t take accountability for having ties with someone in the Epstein files. ### 1/5 — EPSTEIN *2026-02-24, version 2.74.4732* Owner of this company has ties with someone in Epstein files. Find another macro tracker. ### 1/5 — Mary *2026-02-09, version 2.74.4732* Tried it, too basic for me, canceled trial then got charged for an annual subscription. No thanks guys. Caliber and my fitness pal do everything I need. ### 1/5 — No trial? *2026-01-01, version 2.74.4680* I’m interested in trialling this as I’m coming up to the end of my annual Cronometer subscription. However, there is no way to do so. I contacted them but they only offered a trial where I have to put my credit card details in. Why not allow a free trial through the App Store … virtually all other apps do. ### 1/5 — Not Internationally Friendly *2025-11-10, version 2.74.4680* Not seeing much of a difference with My Fitness Pal, and the database doesn’t cover NZ or AUS ### 1/5 — No free option *2025-10-30, version 2.73.4628* Scam no free option ### 1/5 — Beware, you don’t need this app *2025-09-30, version 2.73.4495* This app is so bad. There’s nothing advanced or even useful in it. You can’t even set more than one diet goal (seriously? What if I have to keep insulin resistance in check, and also preferably not have a heart attack soon while preventing sarcopenia) ? should have taken the lack of trial period as a red flag and not subscribed. I was influenced by the big names like Dr Lyon and Attia endorcing it. At this point, even the completely free bloatware called veSync which integrates with the smart kitchen scale directly has more options to track your diet and AI coaching features than this paid app. Sigh. ### 1/5 — Bonkers Recommendations *2025-09-01, version 2.72.4216* Kept telling me to eat 900 calories a day when my BMR is 1300 and I workout all the time. That’s not realistic at all ### 1/5 — Heavily marketed for what? *2025-08-21, version 2.72.4216* Dr norton heavily marketed this app like it was something special and offer guidance and directions. Instead I paid $11 for a pure caloric register app that does exactly the same as the original app I use does (free of charge). Plus the first 3 items i barcoded this app did not recognized. Well designed app though. Nice and neat. ## Most praised reviews (10 highest-rated) ### 5/5 — It’s the best!!!!! *2026-08-29, version 2.77.6010* It’s simple, accurate, and comprehensive. 🙂 ### 5/5 — Simple and Effective *2026-08-27, version 2.77.6010* I love how Carbon uses a circle with rings for fat, carb, and protein— it helps me make each meal balanced, rather than simply trying to reach arbitrary numbers by the end of the day. I appreciate such an effective app; it’s rare nowadays to find a product that’s worth the money, but Carbon fits that bill. ### 5/5 — Great *2026-08-25, version 2.77.6010* I have been using this app for 4 months and and I am down so far 12 pounds, but yo be fair I did go on a one month vacation where I added 6 pound. Three weeks after I returned I am back where I stopped before the vacation. ### 5/5 — Amazing! *2026-08-22, version 2.77.6010* Love this app, easy to use and I love how it tailors my intake and updates it weekly. ### 5/5 — Top of the line *2026-08-21, version 2.77.6010* Far superior to any app I’ve used, easy conversions based your preferred measurement (ounces, grams, etc.). Algorithm will adjust your calories +\- based on your scale results, easy to copy meals across multiple days at once if you meal prep… The app keeps getting better! ### 5/5 — Review *2026-08-20, version 2.77.6010* The new photo feature is amazing Game changer for me Now I actually will track everything because trying to search and figure out portions etc , I find very tedious and time consuming This is game changer for me ### 5/5 — Great for being honest with myself *2026-08-20, version 2.77.6010* I’ve used a few other macro trackers and I greatly appreciate that this one calls me out when I’m not compliant. Not only does this keep me consistent with eating habits, but also the weigh-ins. It is completely based on the data you enter. No data, no adjustments and likely less progress. I also really like the option of reverse dieting. They recently changed the one thing I didn’t like: I want to be able to copy previous meals since I meal prep. They made this easier to log, so looking forward to that feature. ### 5/5 — Easy to use *2026-08-18, version 2.77.6010* Straight forward, quick tracking. Bar codes available for most groceries in UK. I use the recipe function a lot as I batch cook 4 portions - lets you measure and list all the ingredients of your own recipe. Then I just add 1 portion each day, so easy and accurate tracking. The calories and compliance are assessed in 1-week cycles. It lets you change your daily calories if you go a bit over on some day, it gets adjusted by reducing calories from the following days. Protein targets are in line with the latest evidence. Plenty of options for different dietary needs, low carb, keto, high protein etc. I’ve been using it for over a year for weight loss and wouldn’t use any other app. I love the simple design. No adds etc. Only the necessary info which makes the app so easy to use even on a busy day. ### 5/5 — Great App *2026-08-18, version 2.77.6010* I have been using this for 2 years and it’s great. It’s is really easy to track everything and the interface is very user friendly. The chat support is great as well and I always get responses very quickly. The feedback given is clear and the adjustments are explained well. Overall great app if you’re looking to cut, bulk, or maintain. ### 5/5 — Trust is the utmost! *2026-08-16, version 2.77.6010* I trust the trends and base my future physical self on it! --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
