Best Carb Manager Alternatives (2026): 6 Keto Apps Compared

Carb Manager has been the default keto tracker for years. In 2026, PlateLens covers the same net carbs, macros, fasting and recipes for free — plus blood-glucose sync and ketone logging Carb Manager's free plan doesn't include — and stays just as useful on the days you're not eating keto. Here's how six apps actually compare, feature by verified feature.

Quick verdict

Best Overall Carb Manager alternative: PlateLens. Automatic net carbs on every meal, a ready-made Keto macro split, a built-in fasting timer, a low-carb recipe and meal planner, and blood-glucose sync plus ketone logging — in an app you can also use for literally anything else you eat. Free plan never expires, no card required.

If you only want Carb Manager’s own ecosystem: Carb Manager itself, with always-free net-carb tracking and unlimited free barcode scans — though PlateLens tracks net carbs automatically for free too, and adds a fasting timer, recipes and blood-glucose/ketone logging in the same free app.

Best for micronutrient depth: Cronometer ($59.99/yr Gold, now with the Crono Coach AI assistant). Best for database size: MyFitnessPal ($79.99/yr Premium to unlock Net Carbs Mode). Best for adaptive coaching: MacroFactor ($71.99/yr, no free plan). Best for simple calorie counting: Lose It! ($79.99/yr Premium for its Keto strategy and net-carb goal).

How we picked

We logged real keto meals in all six apps — net carbs, macros, fasting windows, recipes — to see how each one actually behaves day to day, then checked every price, free-plan detail and net-carb or ketone claim below against the vendor’s own pricing page or official App Store listing. Anything a vendor didn’t spell out clearly, we left out rather than guess.

PlateLens — Best Overall Carb Manager Alternative (82+ Nutrients Tracked Per Meal)

PlateLens covers every keto feature that sends people looking for a Carb Manager alternative in the first place — automatic net carbs, macros, fasting, recipes — in an app that’s just as useful the day you’re not tracking net carbs at all.

Net carbs are calculated automatically on every meal: total carbs minus fiber and sugar alcohols, with total carbs, fiber and sugar all shown alongside it, and your running daily net-carb total compared against your target. Macro targets come with a ready-made Keto split — 25% protein, 5% carbs, 70% fat — or you can set your own custom percentages if your version of low-carb isn’t textbook keto.

The rest of the keto toolkit is built in rather than bolted on: an intermittent-fasting timer for 16:8, OMAD or whatever window you’re running; a recipe and meal planner with low-carb meal ideas and grocery lists; and device sync through Apple Health or Google Health Connect that pulls in blood-glucose readings (included on the free plan) and lets you record ketone readings alongside your food log.

Logging itself is a photo — one shot for a full plate, with voice, text search and barcode scanning all feeding the same diary — pulled against a database of 1.2M+ verified entries from USDA FoodData Central, NCCDB, Open Food Facts and Nutritionix. An AI coach answers questions using your own logged diary as context, and there’s a full web app included rather than gated. There’s no forced upgrade to start using it: manual and barcode logging are unlimited on the free tier indefinitely, no card required, alongside 3 AI photo scans and 5 AI-coach messages per day.

Carb Manager — Best for Staying in the Keto Community You Know (Unlimited Free Barcode Scans Over 1M+ Foods)

Carb Manager was the original keto-specific tracker, and its free plan still covers real ground: food, exercise, water and weight logging, “ALWAYS free” net-carb tracking and unlimited barcode scans over 1M+ foods, plus its keto forums. Premium ($39.99/yr or $8.49/mo) adds 5,000+ keto recipes, the diabetes tracker for glucose, ketones and insulin, intermittent-fasting tools and carb cycling.

Premium, at $39.99/yr, adds recipe importing from other websites, a smart meal planner with a shopping-list generator, voice and natural-language logging, and fitness-device sync with Fitbit and Garmin.

Cronometer — Best for Micronutrient Depth ($59.99/yr Gold with the Crono Coach AI assistant)

Cronometer isn’t a keto specialist, but it’s the deepest general nutrition tracker on this list, and it just picked up an AI layer. The free tier tracks up to 95 nutrients and compounds with custom targets and no card required — genuinely generous for a free plan. Gold, at $59.99/yr, adds Crono Coach, an AI coaching assistant, along with photo-based meal logging (the free tier is search-and-log only).

Cronometer’s web app is one of the best in the category for desktop logging, which matters if you do most of your tracking at a keyboard rather than on your phone. It does include a Keto Calculator and an optional net-carbs setting, but the fasting timer is Gold-only.

MyFitnessPal — Best for Sheer Database Size ($79.99/yr Premium unlocks Net Carbs Mode)

MyFitnessPal’s case for keto users comes down to one thing: if you eat out constantly and need a large restaurant and packaged-food database, its 20.5M+ entries cover it. The free plan covers basic nutrition and weight tracking plus exercise logging.

The catch is that the keto-relevant tools all sit behind Premium, at $79.99/yr — the priciest tier in this comparison. That gets you Net Carbs Mode, barcode scanning, and gram-level and per-meal macro goals, plus bundled intermittent-fasting tools. None of it is free. Premium adds a Low Carb Meal Plan, but MyFitnessPal’s own pages list no ketone or blood-glucose logging — it is a general tracker with a net-carbs setting, not a keto app.

Carb Manager vs MyFitnessPal for keto

This is the most common head-to-head keto users actually ask about, and the answer is straightforward: Carb Manager, for anyone whose main need is net carbs. Its net-carb calculation is automatic and included on the free plan. MyFitnessPal’s equivalent — Net Carbs Mode — is locked to the $79.99/yr Premium plan, along with the barcode scanner you’d want for packaged low-carb foods. MyFitnessPal’s own pages list no ketone tracking; its low-carb recipes and Low Carb Meal Plan also sit behind Premium.

MyFitnessPal’s one real edge is database breadth — if you eat at chain restaurants often, its packaged-food and menu-item coverage runs to 20.5M+ entries. For a dedicated keto workflow specifically, that’s the whole case for it; net carbs isn’t.

MacroFactor — Best for Adaptive Macro Coaching ($71.99/yr, no free plan)

MacroFactor takes a different approach entirely: instead of a fixed keto macro split, its algorithm recalculates your macro and calorie targets from your own logged weight-trend data, so your numbers move as your actual results do. Logging includes AI photo recognition, barcode scanning and a 1.36M-entry food database, and the interface is clean and ad-free with strong educational content baked in.

There’s no free plan — $71.99/yr starts once the trial ends — and no web app for logging, iOS and Android only per MacroFactor’s own FAQ. For keto users specifically, its macro program includes a keto diet plan that the algorithm keeps adjusting; net-carb and ketone tracking aren’t features it advertises.

Lose It! — Best for Simple Calorie Counting ($79.99/yr Premium)

Lose It! is a mainstream calorie counter. Premium is $79.99/yr, and the free plan covers calorie tracking, a personalized weight-loss plan and community support. Photo logging and barcode scanning both come with Premium.

On Premium, Lose It! adds a Keto nutrition strategy, a custom net-carb goal and an intermittent-fasting tracker, alongside macro, vitamin, mineral and blood-glucose tracking. None of that is on the free plan, which is calorie counting only.

Bottom line

Carb Manager pioneered keto-specific tracking, and its always-free net-carb tracking and forum community are real reasons some users stay on its free tier. But for keto users who want net carbs, macros, fasting, recipes and blood-glucose/ketone logging handled in one app — free, without Carb Manager’s Premium paywall on recipes and glucose/ketone tracking — PlateLens is the stronger pick in 2026.
