Turn today's food into a clearer next step.
See how food changes the day, understand what pushed your targets off balance, and get a practical suggestion for what to change next.
Carb Manager gives you a broad keto and metabolic health toolkit. Keto.app is more focused on making your next keto decision clear.
Both apps can track net carbs and macros. The bigger difference is what happens after you log the food.
Carb Manager is built as a broad toolkit. Keto.app is built around a simpler question: am I still on track, and what should I do next?
You can still fit them today, but dinner will need to stay very low carb.
Choose a low-carb dinner and you can finish the day close to your targets.
The real difference
The apps overlap on the basics. Their product philosophy is where the comparison gets interesting.
See how food changes the day, understand what pushed your targets off balance, and get a practical suggestion for what to change next.
Track macros and food alongside recipes, community, education, exercise and advanced metabolic health data.
A comparison page should not pretend one app wins every row. The useful question is which product is built around the problem you actually want solved.
Quick comparison
Instead of a long list of yes/no checkmarks, this table compares what each app is built to do best.
Features and product positioning can change. Carb Manager descriptions here are based on its publicly available feature pages and store listings reviewed in July 2026.
Before you log it
Keto.app is designed to show the effect of a food in the context of what you have already eaten today.
A dashboard can show that carbs went high. The next useful step is understanding why — and what to change tomorrow.
AI day analysis

Common questions
Direct answers about net carbs, pricing, languages and who each app fits.
Yes. Keto.app subtracts fiber and sugar alcohols automatically, so net carbs are the main number on your daily dashboard.
Keto.app is free to download and use. PRO is only needed to log 5 or more foods a day, and it comes as a monthly or yearly subscription or a one-time lifetime purchase.
Keto.app is available in 15 languages, including Spanish, German, French, Portuguese and Russian. Carb Manager’s App Store listing is in English only.
Yes. Carb Manager Premium includes blood glucose, ketone and insulin tracking. Keto.app focuses on food, net carbs and the daily keto routine instead.
Choose Carb Manager if you want a large recipe and meal planning ecosystem, community and education in the app, or biomarker tracking alongside your food log.
Choose Keto.app if you want to see whether a food fits today’s carb budget before you log it, understand what changed your day, and follow ready-made keto plans when you don’t want to plan meals.
Both can track keto. If your main problem is not collecting more data, but knowing what today's data means for your next meal, try Keto.app.
