Best Carb Tracker Apps in 2026

You want to track your carbs, but you do not feel like weighing every broccoli floret on a kitchen scale and logging it by hand. Fair. There are plenty of apps that make it easier, but which one actually fits your routine? I put five popular carb tracker apps side by side.

Why use a carb tracker?

Whether you are doing keto, eating low-carb or just paying more attention to what you eat, tracking carbs works. Not because counting is magical, but because it surfaces patterns you would otherwise miss.

That yoghurt you eat every morning? 18 grams of carbs. The so-called healthy crackers at lunch? Another 24 grams. Without tracking, almost everyone underestimates intake. Studies consistently show people underestimate carb intake by 30 to 50 percent.

A good carb tracker solves three things:

  1. Fast logging. Scan a barcode, snap a photo or search a database. No mental arithmetic.
  2. Overview. How much have you had today, how much budget is left, how do you trend across the week.
  3. Awareness. After two weeks of tracking you know exactly which foods derail you and which are safe.

The difference between apps is how they handle those three jobs. Some are built for keto and low-carb, others are general calorie counters where you have to manually surface carbs.

I compare on six points: ease of use, accuracy of the food database, carb-specific features, photo logging, price and extras. For each app I list the strong and weak points honestly.

What to look for when picking

Not every carb tracker fits every situation. Three things make the real difference.

Net carbs vs total carbs

If you eat low-carb or keto, you want net carbs. That is total carbs minus fibre. Fibre does not raise blood sugar, so it does not count against your daily limit.

It sounds like a detail but it changes the picture. An avocado has 9 grams of total carbs but only 2 grams net. If your app only tracks totals, the avocado looks much worse than it actually is.

Of the five apps, Ketomi and Carb Manager track net carbs by default. With MyFitnessPal, Lifesum and FatSecret you do the maths yourself.

Speed of logging

The best carb tracker is the one you actually keep using. If logging a meal takes more than 30 seconds, you will quit within a week.

Barcode scanning is fast when the product is in the database. Photo analysis (like Ketomi) is fast when you cannot be bothered to search. Manual entry is always slowest. Pick the method that fits your routine.

Database quality, not just size

MyFitnessPal has 14 million entries, but a chunk of them are user-submitted and wrong. Carb Manager has cleaner data but fewer international products. Ketomi has fewer entries overall, but the photo analysis makes the database size less important: the AI estimates whatever is on your plate.

Tip: try the app for the first three days with foods you eat regularly. If half of them are missing or wildly off, you have your answer.

Which app fits you?

No app is best for everyone. It depends on your situation.

The catch with "free"

FatSecret and the free tiers of MyFitnessPal and Carb Manager are attractive because they cost nothing. But free has its price. Ads, limited reports, no exports, features behind paywalls the moment you actually want to use them.

More importantly: free apps almost always lack coaching. You get a counter, not an explanation. Over your daily limit? The app tells you, but not what to do about it. That is the difference between a calculator and a coach.

Paid apps cost $4 to $13 per month depending on which you pick and whether you pay monthly or yearly. On an annual basis Ketomi works out to $4.17 per month. Compare that to a single dietitian session ($50 to $100) and the maths is short.

Transparency. Ketomi is our own app. This comparison is written as fairly as possible: we name where others are better (database size, barcode scanner) and where Ketomi is stronger (AI coaching, photo logging). Prices are as of May 2026 and can change.

Conclusion

If you want a carb tracker that does more than print numbers, Ketomi is the most rounded option. AI coaching, photo analysis and tailored meal plans make the difference, especially when you are just starting.

Want the biggest database? MyFitnessPal is strong, though you will compute net carbs yourself. Want keto-specific tracking with a top scanner? Carb Manager. Budget zero? FatSecret nails the basics.

The good news: almost every app has a free trial or a free tier. Try two side by side for a week and keep the one you actually open on day seven.

Frequently asked questions

Which carb tracker app is the most accurate?

Accuracy depends on the database and how you log. MyFitnessPal has the biggest database but includes user-submitted entries with errors. Carb Manager is more accurate for keto products. Ketomi uses AI photo analysis for a fast estimate without manual searching.

Can I track carbs for free?

Yes. MyFitnessPal, Carb Manager and FatSecret have free tiers that let you track carbs. The free versions have ads, fewer features or limited reports. For serious tracking a paid app pays for itself fast.

What is the difference between net and total carbs?

Total carbs include sugars, starch and fibre. Net carbs are total minus fibre, because fibre does not raise blood sugar. On keto you usually count net carbs. Ketomi and Carb Manager do this by default; with other apps you calculate it yourself.

Do I need to count carbs on keto?

Yes, at first. Most people underestimate how many carbs are in everyday foods. After a few weeks you get a feel for it.

How many carbs per day to stay in ketosis?

The common guideline is up to 20 to 30 grams of net carbs per day. Some people can eat up to 50 and stay in ketosis. Start strict and experiment later. A tracker helps you stay within range.

Which carb tracker has the best photo logging?

Ketomi is the only app in this comparison with built-in AI photo analysis. You snap a picture of your plate and the app estimates the macros, including net carbs.
