If you follow a ketogenic diet, you already know that total carbs only tell half the story. Net carbs — total carbohydrates minus fiber and certain sugar alcohols — are what most keto eaters actually count, and not every nutrition app handles the math for you. The best app for tracking net carbs does the subtraction automatically, shows your remaining carb budget at a glance, and makes logging fast enough that you actually stick with it. We compared fifteen popular trackers on how well they handle net carbs specifically: whether net carbs are a first-class number or a buried setting, how accurate their food databases tend to be for keto staples, and what the free tier really gives you. Some of these are keto-first apps built entirely around carb counting, while others are general trackers with a solid net carb mode. Based on publicly available information, all fifteen offer something genuinely useful for low-carb eaters — the right pick depends on whether you want simplicity, micronutrient depth, or AI-powered logging. This roundup is based on publicly available information as of July 27, 2026. Features and pricing may change. We encourage readers to try a few apps to find what works best for them.

Keto-First Apps Built Around Net Carb Tracking
1. Carb Manager — According to their website, Carb Manager is built from the ground up for keto and low-carb dieters, and net carbs are the core feature rather than an afterthought. The dashboard leads with your net carb count, the food database flags keto-friendly items, and premium adds keto meal plans, recipes, and glucose integrations. If you want a keto carb counter app that assumes you are keto from day one, this is the most obvious starting point. 2. Keto Diet App — This one pairs a net carb tracker with a large library of original keto recipes, which is helpful if your main struggle is figuring out what to cook rather than what to log. Based on publicly available information, the recipe database is written by the app's own team, so macros for each dish are pre-calculated. 3. Senza — Senza markets itself as a keto companion for beginners, with a guided first week, net carb tracking, and access to keto coaches on paid plans. As of this writing, it emphasizes education alongside logging, which suits people brand new to the diet. 4. KetoDiet — A long-running keto-niche app with net carb tracking, planning tools, and a research-oriented blog. According to their site, it focuses on whole-food keto rather than processed low-carb products, and it appeals to people who want opinionated guidance. 5. Stupid Simple Keto — True to its name, this app strips carb tracking down to the essentials: log food, see net carbs left, done. Based on publicly available information, it uses visual portion logging so you can track without weighing everything, which makes it a good fit for people who abandon detailed trackers.
General Trackers With Strong Net Carb Support
6. Cronometer — Cronometer's free tier tracks over 80 micronutrients, which matters more on keto than most diets because electrolytes, magnesium, and potassium are common shortfalls. It supports net carb display and its database leans on verified lab-sourced data, so fiber values — the key to accurate net carbs — tend to be trustworthy. A top pick for detail-oriented keto eaters. 7. MyFitnessPal — The biggest food database in the category, with a net carbs view available on premium plans as of this writing. The catch: the barcode scanner has been paywalled since 2022, and user-submitted database entries can have unreliable fiber values, so double-check keto staples. Still a reasonable choice if you already have history there. 8. MacroFactor — MacroFactor is subscription-only after a free trial, but its adaptive TDEE algorithm adjusts your targets weekly based on your actual weight trend — useful if you are using keto for fat loss and want your carb and calorie budget to stay honest. Logging is notably fast, and it can display net carbs. 9. Intake — Intake Nutrition is an AI-powered iOS tracker that lets you log meals by photo, voice, or barcode, with an AI coach for questions like whether a food fits your carb budget. For keto eaters, the appeal is speed: snap a plate and the AI estimates the macros, including carbs and fiber, instead of you searching a database entry by entry. It is free to try, and based on publicly available information it suits people who quit traditional trackers because logging felt like a chore. 10. MyNetDiary — MyNetDiary offers a dedicated low-carb and keto mode with net carb tracking, plus a clean daily analysis of how you are pacing against your budget. According to their website, its database is curated by an in-house team, which helps with fiber accuracy.
Simple and Lifestyle-Focused Options for Low-Carb Eaters
11. Lose It — A friendly general tracker with a low-carb plan option and net carb display on premium. Its Snap It photo logging and pattern insights make it approachable, and the free tier is usable for basic carb counting even if some features sit behind the paywall. 12. FatSecret — One of the few fully free trackers, with barcode scanning, a large database, and community features at no cost. It shows total carbs and fiber so you can do the net carb math, though as of this writing net carbs are less front-and-center than in keto-first apps. Hard to beat on price. 13. Lifesum — Lifesum offers a dedicated keto plan with net carb targets and a design-forward interface that rates meals as you log them. Based on publicly available information, most of the keto-specific features require premium, but the experience is one of the most pleasant in the category. 14. Yazio — Yazio includes a low-carb plan, fasting timers, and simple carb tracking in a clean interface. It is popular with people who want a light-touch tracker rather than a data-heavy one, and its free tier covers basic logging. 15. 8fit-style meal planners — A final category rather than a single app: planner-first apps in the 8fit mold generate low-carb meal plans and grocery lists, then treat tracking as secondary. If your problem is deciding what to eat rather than logging what you ate, pairing a planner like this with a lightweight net carb tracker can work better than one heavyweight app. Bottom line: Carb Manager is the strongest pure keto carb counter app, Cronometer wins for nutrient depth, and Intake or Stupid Simple Keto suit people who want logging to take seconds instead of minutes.
Frequently Asked Questions
What is the best app for tracking net carbs?
Carb Manager is the most popular keto-first option because net carbs are its core feature, based on publicly available information. Cronometer is a strong alternative if you also want deep micronutrient tracking, and Intake suits people who prefer AI photo and voice logging over database searches.
How do apps calculate net carbs?
Most apps subtract fiber, and sometimes certain sugar alcohols, from total carbohydrates. Accuracy depends on the food database having correct fiber values, which is why curated databases like Cronometer's and MyNetDiary's tend to produce more reliable net carb numbers than fully crowdsourced ones.
Is there a free keto carb counter app?
FatSecret is one of the few fully free trackers and shows carbs and fiber so you can count net carbs at no cost. Cronometer's free tier also supports low-carb tracking, and Intake is free to try. Most keto-first apps like Carb Manager reserve advanced features for premium.
Does MyFitnessPal track net carbs?
As of this writing, MyFitnessPal displays net carbs as part of its premium plans rather than the free tier. Free users can still see total carbs and fiber and do the subtraction manually, but keto-first apps make this easier.
How many net carbs should I eat on keto?
Most keto guidance suggests staying under 20 to 50 grams of net carbs per day to maintain ketosis, though individual tolerance varies. A tracking app helps you find your personal threshold, and it is worth confirming your approach with a healthcare professional.
