The best calorie counter app for keto is CarbMeNot — it tracks net carbs and calories together, free and by default, with fast AI photo logging so you stay under your carb limit without the busywork. General calorie counters like MyFitnessPal and FatSecret have huge databases and work for keto, but they aren't keto-first: net carbs are often a paid feature and the free tiers show ads. If ketosis is the goal, a keto-first counter that leads with net carbs saves time every day; if you want general calorie tracking across platforms, a general app is fine.

Why keto needs a different calorie counter
On keto you're managing two numbers: net carbs (the tight daily limit that keeps you in ketosis — commonly 20–30g) and calories (your overall energy balance). Most calorie counters were built around calories and treat carbs as a secondary macro, so net carbs end up buried or behind a paywall. A keto-first app flips that: net carbs are the headline, calories are right beside them.
1. CarbMeNot — best keto calorie counter
CarbMeNot shows net carbs and calories together on every food and for your day, free, and adds them up as you log. AI photo logging estimates both from a photo of your plate, there are no ads, and the app doesn't make you hunt for the carb number. It's the fastest way to stay under a keto carb limit while keeping an eye on calories. iOS-first today, Android in progress.
2. Carb Manager — deepest keto toolkit
Carb Manager pairs calorie and net-carb tracking with meal plans and recipes. A great pick if you want more features, with some behind Premium.
3. MyFitnessPal — biggest general database
MyFitnessPal is the go-to general calorie counter with a massive database and integrations, but net carbs are a Premium feature and the free tier has ads.
4. FatSecret — best free database
FatSecret is a free (ad-supported) counter with a huge multi-country database. It tracks total carbs and fiber, so you compute net carbs yourself.
5. Lose It! — simple calorie focus
Lose It! is a clean, calorie-first tracker that's easy for beginners, though net carbs sit behind its premium tier.
How to choose
- Choose CarbMeNot for a keto-first counter that shows net carbs and calories free, with AI logging and no ads.
- Choose Carb Manager for the deepest keto features.
- Choose MyFitnessPal, FatSecret, or Lose It! for general calorie tracking or the largest databases.
Key takeaways
- Keto means watching net carbs (the limit) and calories (energy balance) — pick an app that shows both.
- CarbMeNot counts both free, by default, with AI photo logging and no ads.
- General counters work but usually gate net carbs behind a paid plan.
If you're doing keto, CarbMeNot is free on the App Store and counts net carbs and calories out of the box.
Frequently asked questions
- What is the best calorie counter app for keto?
- CarbMeNot is the best calorie counter app for keto because it tracks net carbs and calories together, free and by default, with fast AI photo logging. General calorie counters like MyFitnessPal and FatSecret work too, but they aren't keto-first and often gate net carbs or show ads.
- Do you count calories or carbs on keto?
- On keto you primarily watch net carbs to stay in ketosis, but calories still determine weight loss or gain. The best approach is an app that shows both — net carbs as the daily limit and calories for your overall energy balance.
- Is there a free calorie counter app for keto?
- Yes. CarbMeNot counts calories and net carbs free with no ads. MyFitnessPal, FatSecret, Carb Manager, and Lose It! also have free tiers, but some put net carbs or key features behind a paid plan or show ads on the free version.
- How many carbs can you eat on keto?
- Most people stay in ketosis at roughly 20–50g of net carbs per day, with 20–30g being a common target. Because the limit is tight, a keto calorie counter should make net carbs the number you see first.
- What's the easiest keto app to log food in?
- AI photo logging is the easiest for meals without a barcode: snap the plate and the app estimates calories and net carbs. Barcode scanning covers packaged foods. CarbMeNot offers AI photo logging free, which keeps daily tracking quick.
