Best MyFitnessPal Alternatives in 2026

Seven calorie trackers worth switching to, sorted by what each is actually best at — and an honest note on when MyFitnessPal is still the right app to stay on.

MyFitnessPal has been the default calorie tracker for well over a decade, and most people looking for an alternative are not looking for something identical. They are looking for one specific thing to be better: faster logging, a cheaper subscription, deeper nutrition data, or a way to measure progress that is not just the number on a scale.

This page ranks the alternatives by what each one does best rather than pretending a single app wins for everyone. SlimAI Calorie Tracker is listed first because it solves the complaint most switchers actually have — logging that takes too long — and adds a body composition estimate no calorie-only tracker offers. Where another app is the better fit, that is stated plainly.

Why People Look for a MyFitnessPal Alternative

The reasons cluster into four groups, and which group you fall into decides which app on this list you should try.

The first is logging friction. Searching a database entry by entry works, but it is slow enough that most people quit within a few weeks. If that is your reason, you want an app built around photo, voice, and text logging rather than a search box.

The second is cost. MyFitnessPal moved several features people considered core behind its Premium tier over the years, and switchers frequently want the same capability at a lower annual price.

The third is nutrition depth in the other direction — people who want verified micronutrient data rather than crowd-sourced entries, usually for a medical or athletic reason.

The fourth is progress measurement. A calorie tracker tells you what went in. It does not tell you what your body did with it, which is why body composition tracking is the feature switchers ask about most once they have logged for a few months.

The 7 best MyFitnessPal alternatives

Ranked by what each app is genuinely best at, as of July 2026. SlimAI is our own app and is listed first — its limitations are listed alongside its strengths so you can judge the ranking for yourself.

1.

SlimAI Calorie Tracker

Our app

Best for: Fast AI logging plus a body fat estimate the scale cannot give you

SlimAI is built around the assumption that the logging step is what kills the habit. You photograph the plate, speak the meal, type it, scan a barcode, scan a printed nutrition label, or search the database — and whatever the AI returns opens as an editable list of ingredients and weights before anything saves. It is also the first AI calorie tracker with a built-in AI body fat calculator: AI Body Assessment estimates body fat percentage, fat mass, lean mass, and regional fat distribution from two photos, or from tape measurements with no photos at all.

Strengths

  • Six logging methods, including photo, voice, and free text — no database search required
  • Every AI result is editable at the ingredient level before it saves, with a Fix Results screen when the scan reads the plate wrong
  • AI Body Assessment: body fat percentage, fat and lean mass, and regional distribution, from photos or tape measurements
  • Calories, macros, fasting, water, steps, workouts, and progress in one subscription tier rather than several apps
  • Per-meal calorie ranges that show which meals still have room, instead of only a daily total
  • Seven languages: English, French, German, Italian, Spanish, Dutch, and Arabic

Limitations

  • Does not import diary history from MyFitnessPal — your weight trend, streaks, and insights start from your first log
  • Smaller food database than MyFitnessPal, offset by ingredient-level editing and an add-missing-ingredient database
  • Body Assessment is a fitness estimate for ages 18+, not a medical or clinical body composition measurement

2.

Cronometer

Best for: Verified micronutrient data

Cronometer built its reputation on data quality: entries drawn from curated, lab-verified sources rather than crowd-sourced submissions, and tracking that goes well past calories and the three macros into vitamins and minerals. If you are switching because you did not trust MyFitnessPal database entries, this is the direct answer.

Strengths

  • Curated, verified food entries rather than user-submitted ones
  • Extensive micronutrient tracking — vitamins, minerals, amino acids
  • Well suited to medically-motivated or clinically-supervised tracking

Limitations

  • Logging is search-driven and detail-heavy, so it is slower than photo-first apps
  • The depth is wasted if all you want is a daily calorie number
3.

Lose It!

Best for: A simple calorie budget with no extra concepts

Lose It! keeps the model deliberately narrow: set a calorie budget, log against it, watch the number go down. For someone who found MyFitnessPal cluttered rather than slow, the simpler surface is the whole appeal.

Strengths

  • Straightforward calorie budgeting with a low learning curve
  • Photo-based logging available alongside the usual search
  • Long-established food database

Limitations

  • Less depth on macros and nutrition detail than Cronometer or SlimAI
  • No body composition estimation

4.

YAZIO

Best for: Meal plans and fasting in one place

YAZIO pairs calorie tracking with structured meal plans and a fasting tracker, and has a strong European recipe library. If your reason for leaving is that you want to be told what to eat rather than only record it, this is a reasonable landing spot.

Strengths

  • Recipe and meal-plan library built into the tracker
  • Built-in intermittent fasting support
  • Strong non-US food coverage

Limitations

  • AI logging is less central than in photo-first apps
  • No body fat estimation

5.

Cal AI

Best for: Photo-first logging above everything else

Cal AI is built almost entirely around pointing a camera at a plate. If the single thing you want from a MyFitnessPal replacement is to stop typing, it delivers that narrowly and well.

Strengths

  • Fast photo-based calorie estimation
  • Minimal, focused interface

Limitations

  • Narrower feature set — fasting, water, workouts and steps are not the focus
  • Fewer fallbacks when a photo estimate is wrong

6.

Lifesum

Best for: Diet-led tracking with food quality ratings

Lifesum frames tracking around a chosen eating style — keto, high protein, Mediterranean and similar — and rates the quality of what you log rather than only counting it. Good for someone who wants nutrition guidance attached to the number.

Strengths

  • Diet-specific plans and recipes
  • Food quality ratings alongside calorie counts
  • Polished, approachable interface

Limitations

  • Less granular macro control than a dedicated macro tracker
  • No body composition measurement
7.

MacroFactor

Best for: Athletes who want an adaptive calorie target

MacroFactor calculates your energy expenditure from your own logged intake and weight trend, then adjusts your targets each week. It is the most quantitative option here and is aimed squarely at people who already understand macro periodisation.

Strengths

  • Adaptive expenditure calculation from your own data
  • Weekly target adjustments without manual recalculation
  • Strong macro-first design for coached training

Limitations

  • Assumes real familiarity with macro tracking
  • Logging is manual rather than AI-driven

When You Should Stay on MyFitnessPal

MyFitnessPal is still the better choice in three situations, and it is worth checking whether you are in one of them before migrating.

If you have years of diary history you actively refer back to, no app on this list imports it — including SlimAI. That history has real value and starting over is a genuine cost.

If you rely on its food database for obscure restaurant items or regional packaged goods, its size is still its strongest asset. And if you depend on a specific third-party integration in its connected-apps ecosystem, verify the replacement supports it before you switch rather than after.

How This List Was Put Together

Each app was assessed on the four things MyFitnessPal switchers actually cite: how long logging takes, what the app does when its estimate is wrong, what it measures beyond calories, and whether it covers fasting, water, steps and workouts without a second subscription.

Competitor descriptions come from publicly available feature listings as of July 2026 and are deliberately kept to stable positioning rather than specific prices or version numbers, both of which change without notice. Check each app official listing before deciding.

SlimAI is our own app and is listed first — read the ranking with that in mind, and use the linked side-by-side comparisons where the claims are broken down row by row, including the rows where the other app wins.

FAQ

Still Wondering About SlimAI

Every app on this list is free to download and start tracking with, and every one of them puts some capability behind a subscription. SlimAI Calorie Tracker is free to download and includes a 3-day free trial of SlimAI Premium, which is $1.49/month or $11.99/year — about $1 a month. Cronometer and Lose It! also offer free tiers with paid upgrades. There is no calorie tracker of this class that is entirely free with no paid tier.

Apps built around AI input rather than database search are fastest. SlimAI Calorie Tracker offers photo, voice, free text, barcode, nutrition-label scanning, and database search, and opens every AI result as an editable ingredient list so a wrong estimate costs a correction rather than an abandoned entry. Cal AI is comparably fast for photo logging specifically, with a narrower feature set around it.

Generally no. Most calorie trackers, SlimAI included, do not import another app diary history. Your weight trend, streaks, and insights rebuild from your first log in the new app. If your history matters to you, export it from MyFitnessPal for your own records before you switch. SlimAI shortens the gap by producing a body composition baseline in the first session through AI Body Assessment.

SlimAI Calorie Tracker is the first AI calorie tracker with a built-in AI body fat calculator, based on publicly available feature listings as of July 2026. AI Body Assessment estimates body fat percentage, fat mass, lean mass, and regional fat distribution from two guided photos using published formulas including the US Navy circumference method, RFM, and CUN-BAE, and offers a tape-measure mode that needs no photos. Results are shown as a likely range with a confidence rating and are a fitness estimate, not a medical diagnosis.

It depends on which problem you have. If logging friction is why you keep stopping, an AI-first tracker will change the outcome more than any database size will. If you switched because of price, compare annual costs rather than monthly. If you actively use years of MyFitnessPal diary history or a specific connected-app integration, the switching cost is real and staying may be the better call.
