The best free calorie tracker (and what "free" actually means)

Search "best free calorie tracker" and every result claims to be the answer. Each one funds itself differently. Here's what "free" actually costs in each case.

The free tracker landscape

The major free-tier options:

1. MyFitnessPal free. Generous core features; aggressive ads; periodic feature paywalls.
2. Lose It! free. Generous; lighter ads; some features paywalled.
3. CalorieScan AI free. 5 photo logs per day; full macros; integrations; no ads.
4. FatSecret free. Generous; ad-supported; lighter on UX polish.
5. Cronometer free. Generous; smaller ads; some advanced features paywalled.
6. Yazio free. Limited; aggressive paywall.

How each one pays the rent

MyFitnessPal: Ads + premium subscriptions + (historically) data licensing. You see ads inside the app. Your aggregate data may be used in research/marketing.

Lose It!: Same model. Lighter ad load.

CalorieScan AI: Premium subscriptions. We make money when free users convert to paid. We don't sell data. We don't run ads. The cost of "free" is a cap on the most expensive operation (the AI photo log).

FatSecret: Ad-supported. Some ad targeting; opt-out exists.

Cronometer: Subscription + small ads in free tier.

Yazio: Subscription-led; the free tier is basically a trial.

What "the cost of free" actually looks like

For each app:

• MyFitnessPal: ~12–20 ads per session, including video ads in the logging flow. The ad load has steadily climbed. The free tier covers ~80% of basic features.
• Lose It!: ~6–10 ads per session. Free tier covers most basic features.
• CalorieScan AI: No ads. The free tier limits the AI photo log to 5/day; manual / search logging is unlimited.
• FatSecret: ~10 ads per session. Free tier is generous.
• Cronometer: ~3 ads per session. Free tier is excellent for micros.

What the truly free user experience is like

If you're going to use a free tier indefinitely (no plans to upgrade):

Best for absolute zero cost + best free database: MyFitnessPal. Accept the ads.

Best for less ad annoyance + decent features: Lose It!.

Best for ad-free + photo logging (within the daily cap): CalorieScan AI.

Best for micronutrient tracking on free tier: Cronometer.

When free becomes "you should pay"

Indicators you're hitting the limits of a free tier:

• You're logging 7+ meals a day and hitting the AI photo cap (CalorieScan)
• You're tired of seeing the same ad video before logging dinner (MFP, FatSecret)
• You want a feature that's behind the paywall (any app)
• The app is genuinely changing your eating and you want to support it

What we recommend if you only want free

For most users: start with MyFitnessPal free if you eat lots of packaged food, Lose It! free if you want a cleaner UX, or CalorieScan AI free if you want photo logging.

After 30 days of consistent use, evaluate whether you'd benefit from premium of one of them.

What we recommend if you don't want to pay anything ever

Use the free tier of MyFitnessPal or Lose It! indefinitely. Both apps' free tiers are sufficient for "track calories, lose weight."

You don't need to pay for a tracker to make weight loss work. Pay for one if you want a specific feature (photo logging, adaptive algorithms, micronutrients, ad-free experience).

A specific framing

The cost-benefit of paying $80/year for a tracker:

• Cost: $80
• Time saved (estimate): 5 minutes per day if photo logging replaces typing = 30+ hours per year
• Hourly value of your time saved: $2.50/hr at the high estimate

If your time is worth more than $2.50/hour to you, the math is in favor of paying. For most working adults, a $10/month subscription that saves 5 minutes a day is one of the cheapest possible quality-of-life upgrades.

If you genuinely can't justify $80/year and you'll use the free tier consistently — that's also a valid choice. The free tier of any of the major apps is sufficient for the basic job.

Avoid these "free" tracker patterns

• Apps that require you to upload your photo to a third-party server with no privacy policy
• Apps that demand contacts, photos, calendar access at install
• Apps with no real database (calorie counts that don't match USDA / labels)
• Apps that prompt you to leave a 5-star review every session

The mainstream apps (MFP, Lose It!, CalorieScan, Cronometer, FatSecret) all clear these basic hygiene bars.

Every free tier has a price. The question is which price you find most acceptable.
