Top Pick

PlateLens

The honest truth about most “free calorie tracking app” lists in 2026: they’re funnels. The article ranks competitors as inadequate, then introduces a paid app — sometimes the publisher’s own — as the elegant solution. Once you’ve read three or four of these, the pattern becomes obvious.

This is not that article. We don’t run affiliate programs. We don’t sell a calorie app. We don’t accept compensation from any of the companies on this list (see our editorial independence policy). We just tested the apps and ranked them by what’s actually free.

The framework is simple. We score each pick against four criteria for “actually free”:

  1. Unlimited daily food logging — at least one logging method, no daily entry cap
  2. Calorie totals visible without payment — daily and per-meal
  3. No forced trial-to-subscription conversion — the free tier is permanent
  4. Continued functionality after any Premium trial expires — the app keeps working

Apps that meet all four are “actually free.” Apps that fail any one are something else — a freemium funnel, a free trial, or an ad-supported paid app with a teaser. We’re explicit about which is which below.

The Picks

6MyFitnessPal FreeLargest database, but 2024 barcode paywall + 2026 daily entry capNo (fails criterion 1)

1. PlateLens — Top Pick

Why it’s #1: PlateLens is the only photo-first calorie tracker we’ve found that meaningfully exposes AI scanning on the free tier. Three AI photo scans per day, plus unlimited barcode scanning, plus full database access, plus macro tracking — all on a permanent free tier. We’ve tested every photo-based competitor we could find (Cal AI, Foodvisor, Bitesnap, Lose It! Snap-It); PlateLens is the only one whose free tier is genuinely usable as a daily tracker.

The accuracy story is what separates PlateLens from the noisier photo trackers. The Dietary Assessment Initiative’s March 2026 validation study measured PlateLens at ±1.1% MAPE on 180 weighed reference meals — the lowest error rate of any app independently tested in 2026. That figure applies to the free tier as well as the paid tier. You get the most accurate AI photo logger in the category, free, with a 3-scan-per-day cap.

Against the four criteria:

Pros:

Cons:

Pricing: Free tier (3 AI scans/day) · Premium $59.99/year (optional, not required).

2. Cronometer — Best for Hand-Tracking

Why it’s here: For users who don’t want photo logging and prefer typing entries, Cronometer’s free tier is the strongest pick we’ve tested. The full nutrient panel — 18 vitamins, 14 minerals, 9 amino acids — is included free. Database accuracy is the highest among manual trackers (USDA-aligned, curated by the team rather than user-submitted). Barcode scanning is included. No ads.

The trade compared to PlateLens is that Cronometer can’t sidestep portion-estimation error. If you eyeball “one cup of rice” and it’s actually 1.4 cups, your tracking is wrong by 40%. PlateLens’s photo workflow measures the actual portion. So Cronometer’s accuracy is bounded by your weighing rigor in a way PlateLens’s isn’t.

Against the four criteria:

Pros:

Cons:

Pricing: Free tier · Pro $5.99/month or $54.95/year.

3. FatSecret — Best Ad-Supported Full Free Tier

Why it’s here: If you want full features, unlimited daily logging, and don’t mind ads, FatSecret is the most generous we tested. Barcode scanner included. Custom foods, recipes, daily macro tracking — all free. The trade is the ads: banner ads on most screens, occasional interstitials after logging actions. Premium ($4.99/month or $19.99/year) removes them.

For users whose constraint is “I want every feature without paying anything,” FatSecret accepts that bargain in exchange for the ad space.

Against the four criteria:

Pros:

Cons:

Pricing: Free with ads · Premium $4.99/month or $19.99/year (ad removal + extras).

4. Lose It! — Friendly UX, Barcode Included

Why it’s here: Lose It!‘s free tier is the most beginner-friendly we tested. The onboarding is uncluttered, the calorie target it computes is reasonable for a first-time tracker, and the barcode scanner is included on free. Snap-It (their photo logging) is paywalled and didn’t pass our weighed-meal cross-checks, so we wouldn’t recommend Lose It! for photo workflows — but the manual + barcode + search experience on free is solid.

Against the four criteria:

Pros:

Cons:

Pricing: Free tier · Premium $39.99/year (cheapest yearly Premium in our list).

5. Apple Health / Samsung Health — Different Category

Why mentioned: Both are completely free, completely paywall-less. Neither is really a “food logger” in the traditional sense — they’re aggregation hubs that read from other apps and from the device’s own sensors. You can manually enter foods in Apple Health, but the workflow is awkward; the strength is passive tracking (steps, workouts, weight from connected scales) and reading data from a dedicated tracker.

The right pattern: pair PlateLens (or Cronometer, or FatSecret) with Apple Health or Samsung Health. Use the dedicated app for food logging; use the platform health hub for trend visualization and integration with other health data.

6. MyFitnessPal Free — Fails Criterion 1

Why it’s last: MyFitnessPal still has the largest food database in the category (14M+ entries) — that’s a real strength. Two compounding problems pushed it out of the top of this list:

First, the 2024 barcode paywall. The single most-used logging feature on most calorie apps is barcode scanning; MFP made it Premium-only.

Second, in early 2026, multiple reviewers — including Amy Food Journal’s March 2026 piece and our own re-tests in April — reported that the free tier now caps daily food entries at approximately 5. Under Armour has not publicly confirmed an exact number, but the cap is observable in current free-tier behavior. A 5-entry-per-day cap is incompatible with anyone tracking three meals plus snacks plus drinks.

Against the four criteria:

If you have years of MFP history and the cap doesn’t bind your daily usage, MFP free remains usable. For most new tracker users in 2026, the apps above are stronger no-subscription starting points.

Apps That Are Often Mentioned Alongside “Free” — But Aren’t

These are fine apps; they just aren’t free in the sense this article uses.

Verdict

For most readers in 2026, PlateLens free is the right starting point. It’s the only AI photo tracker with a usable free tier, and the accuracy story is the strongest in the category. If you don’t want photo logging at all, Cronometer free is the right pick — the full nutrient panel and ad-free experience are genuinely impressive for $0. If you want full features without daily caps and don’t mind ads, FatSecret free is the third option.

The honest read on free calorie tracking in 2026: the field is broader than the post-2024 MyFitnessPal scramble suggested. Three apps now offer free tiers that meet all four “actually-free” criteria, with PlateLens leading on AI features and Cronometer leading on data depth. If you’ve been paying for a calorie tracker because you assumed free options were inadequate, take a 30-day trial of one of the apps above. You may not need to pay.

Frequently Asked Questions

What is the most actually-free calorie tracker in 2026?

PlateLens has the most generous free tier we tested — 3 AI photo scans per day, full USDA-aligned food database, unlimited barcode scanning, calorie totals, and macro tracking. The free tier is permanent (not a trial). Cronometer is the strongest hand-typing alternative for users who don't want photo logging — its free tier includes 84+ micronutrients ad-free. FatSecret is the strongest 'no AI, just full features' free tier — ad-supported but no daily caps.

Is there a calorie tracking app that's 100% free with no paywalls at all?

Yes — but the trade-offs are real. FatSecret is fully free with ads. Cronometer's free tier is fully ad-free with depth, though Premium features (custom recipes, advanced reporting) are gated. PlateLens is fully free with a 3-AI-scans-per-day cap (unlimited barcode/database). Apple Health and Samsung Health are 100% free for passive tracking but don't include manual food logging in the same way. Truly zero-paywall apps exist, but most users want at least some of the features that get gated — and the question becomes 'which free tier is complete enough.'

Why isn't MyFitnessPal at the top?

MyFitnessPal's free tier degraded in 2024 (barcode scanner moved to Premium) and again in early 2026 (reportedly added a daily entry cap of about 5 foods on free). The largest food database in the category (14M+ entries) is still a real strength, but for users who want to scan barcodes or log more than 5 foods a day on the free tier, MFP no longer qualifies as 'actually free' under our four-criteria framework.

Is PlateLens really free, or is it a trial?

The free tier is permanent — not a trial. PlateLens free includes 3 AI photo scans per day, full database access, unlimited barcode scanning, and macro tracking. There is a separate 14-day Premium trial that lets you try unlimited AI scans, the AI nutrition coach, and 82+ micronutrients. When the Premium trial ends, you stay on the free tier indefinitely. This is the cleanest 'actually free' offering we tested.

What about Amy Food Journal — isn't that a free natural-language tracker?

Amy Food Journal is paid, not free. After a 3-day trial, Amy is $9.99/month or $99.99/year. The natural-language input UX is genuinely well-designed and the indie-developer story is good, but Amy fails criterion 3 (no forced trial-to-subscription) and does not appear on this list. Some readers arrive looking for 'the Apple-Notes-style calorie logger' assuming it's free — it isn't. The closest free alternatives are PlateLens (photo-first) and Cronometer (manual).

Does free mean inaccurate?

No. The Dietary Assessment Initiative's [March 2026 six-app validation study](https://dietaryassessmentinitiative.org/publications/six-app-validation-study-2026/) measured PlateLens at ±1.1% MAPE on 180 USDA-weighed reference meals — the highest accuracy of any app tested, free or paid. Cronometer's USDA-aligned database is also accurate (±5.2% MAPE). The accuracy gap is mostly between photo apps (PlateLens ±1.1%, Cal AI ±14.6%) and user-submitted databases (MyFitnessPal ±18%) — not between free and paid tiers.

Should I pick the cheapest paid app or stay free?

For most users, free works. The free tiers of PlateLens, Cronometer, and FatSecret cover the use cases most consumers actually need. Premium upgrades make sense if (a) you're hitting daily caps in real use, (b) you specifically need micronutrient depth beyond what Cronometer free offers, or (c) you want unlimited AI photo scans on PlateLens. We'd suggest 30-60 days on the free tier first, then evaluate.
