Best Keto App in 2026: 9 Apps Compared

Carb Manager is built for keto first, not as an afterthought in a general calorie tracker. Net carb tracking is free, the food database includes many keto foods that general apps miss, and you can set keto macro targets, track ketones, and log glucose on Premium. Premium costs $39.99 per year in recent listings, which is lower than most general trackers, and the free plan covers basic logging without third-party ads in recent comparisons.

New users may find the keto options overwhelming at first, because Carb Manager offers many diet types, fasting timers, and tracking fields. Start with net carbs, protein, and fat, and add ketone or glucose tracking only if you actually use those readings. For a dedicated keto app that shows net carbs without paying, Carb Manager is the clear first choice.

Cronometer suits keto users who care about electrolytes and micronutrients, not just macros. On a long keto run, sodium, potassium, magnesium, and other nutrients matter, and Cronometer tracks up to 85 nutrients with a verified database that is less prone to user-entry errors than larger crowdsourced databases. Custom macro targets are free, and Gold at $59.99 per year adds a macro scheduler, deeper charts, and more customisation.

The trade-off is branded food coverage. Cronometer has fewer restaurant and packaged food entries than MyFitnessPal, so logging a branded keto snack can take longer. It also shows ads on the free plan in recent listings. If you want nutrient depth and verified data, Cronometer is the best choice, while Carb Manager remains better for pure keto convenience.

MyFitnessPal is the best general tracker for keto users who want the largest food database and the easiest logging for restaurant and packaged foods. Barcode scanning, recipe import, and integrations with fitness apps and wearables make daily logging faster, and the community and social features help some users stay consistent. The free plan covers basic calorie and macro tracking, while Premium at $79.99 per year adds net carb display, gram-level macro targets, and per-meal targets.

The honest catch is net carbs. MyFitnessPal gates net carb display behind Premium, which is a real drawback for keto, because net carbs are the number you need daily. If you already use MyFitnessPal and like its database, Premium may be worth it, but if you are starting fresh for keto, Carb Manager gives you net carbs free for less money.

Keto Cycle is built for beginners who want a plan, not just a tracker. An onboarding quiz asks about your weight, activity, food preferences, and goals, then builds a personalised keto meal plan with recipes and shopping guidance. That structure helps new keto users who are unsure how to build a day of meals that stays under their carb limit while hitting protein and fat targets.

Experienced keto users may find Keto Cycle less flexible than Carb Manager or Cronometer, because the focus is on following a plan rather than free logging. Pricing varies by plan length and region, with weekly pricing from about $2.54 per week in some listings, so check the total for your chosen plan before subscribing. Choose Keto Cycle for a guided start, and move to Carb Manager when you want full control over logging.

Eat This Much solves a different keto problem: what to eat, not just how to log it. Tell the app your calories, macros, diet, and budget, and it generates a full day or week of meals that hit your targets, with a grocery list to match. The free plan covers basic planning, while Premium costs $5 to $15 per month depending on plan in recent listings, with annual options lower per month.

The plans are a starting point, not a finished menu. You will still swap meals you dislike, adjust for leftovers, and check portions, but the automation saves the daily maths that puts many people off keto. Eat This Much pairs well with Carb Manager for logging, because planning and tracking are different jobs, and this app does planning best.

Lose It suits beginners who want a simple, friendly tracker without keto jargon. Logging is fast, the interface is clean, and the free plan covers basic calorie and macro tracking with ads. Premium at $79.99 per year in some listings, or $39.99 per year in older listings, adds meal planning, custom macro targets, and more features, so check the current app store price for your region before subscribing.

Lose It is not keto-first. Custom macro targets sit behind Premium, and net carb handling is less central than in Carb Manager, so keto users need to check whether the plan they buy actually shows the numbers they need. It is a good choice for a general weight loss user who is trying keto, but a dedicated keto user will get more from Carb Manager or Cronometer.

MacroFactor is the coaching option here. Instead of fixed macro targets, it adjusts your targets based on logged intake and weight change, estimating your expenditure over time. That adaptive approach suits users who have tracked before and want targets that respond to real progress, rather than a static calculator figure. Pricing is $11.99 per month in recent listings, or $71.99 per year, with a 7-day trial and no free tier.

MacroFactor only works if you log consistently and weigh yourself regularly, because its estimates depend on that data. It also costs more than free trackers, and it does not offer a keto-specific database in the way Carb Manager does. Choose MacroFactor when you want adaptive coaching and are committed to daily logging, and choose Carb Manager when you want a free keto tracker.

YAZIO combines food tracking, recipes, and fasting in one app, which suits keto users who also fast or who want recipe ideas that fit their macros. The free plan covers basic tracking, while Pro adds advanced features, meal plans, and deeper nutrition analysis, with pricing varying by region and plan length. Its recipe library is a strength, because keto can get repetitive without new ideas.

YAZIO is a general nutrition app, not a dedicated keto tracker, so net carb handling and keto-specific foods are less central than in Carb Manager. It fits users who want recipes and fasting alongside tracking, while dedicated keto users should still check whether Pro shows net carbs clearly before paying. For a balanced app with strong recipes, YAZIO is a solid choice.

Lifesum suits users who want a simple, visual app with keto meal plans and habit tracking, rather than a detailed nutrient database. The free plan covers basic tracking, while Premium adds full meal plans, macro customisation, and deeper insights, with pricing varying by region. Its clean design helps beginners who find Carb Manager or Cronometer too detailed at first.

Lifesum is less detailed than Cronometer for micronutrients and less keto-specific than Carb Manager for net carb logging. It works best as a starter app for keto, or as a companion for meal ideas, rather than as a long-term tracker for experienced keto users. If simplicity keeps you logging daily, Lifesum earns its place, but check Premium features before relying on it for strict keto targets.
