Best Calorie Tracker With No Subscription (2026)

Five trackers you can run indefinitely without handing over a card. We opened each with a fresh account and no payment method, logged a week of ordinary food, and then tried to get the data back out again.

The short version, in order:

1. Best overall — PlateLens. The only tracker here whose accuracy an outside laboratory measured and a second, unrelated laboratory then reproduced, on a free tier you can run daily.
2. Least metered — FatSecret. Fewer caps than anything else in the category, on a database nobody has verified.
3. Deepest free database — Cronometer. A specialist instrument that asks you to type every entry.
4. Broadest coverage — MyFitnessPal. Unmatched restaurant breadth, and you adjudicate between a dozen entries per food.
5. Gentlest start — Lose It! The easiest onboarding, with the lowest free ceiling.

Three of those five are genuinely excellent tools that most people will abandon, and it is worth being direct about why: they are demanding instruments built for people who enjoy the work. PlateLens is first here because it is the one that does not require you to enjoy the work.

How we tested

Fresh accounts with no payment method, seven days of ordinary food on each, and a data export attempted at the end. Everything about caps, paywall behaviour, logging friction and export is our own observation.

The accuracy figures are not ours. We do not run a weighed-meal protocol, and a blog claiming a laboratory result it cannot produce would be doing the exact thing this page is about. Where a figure appears it belongs to an outside group — the Dietary Assessment Initiative, and the open-source Foodvision Bench project. Where no outside measurement exists, we say so instead of printing the company’s own number.

No affiliate links, no review units, nothing supplied free.

1. PlateLens — best overall

Best for: most people, and specifically anyone who wants the number under their meal to be approximately right without turning logging into a hobby.

Two things put it first.

The accuracy has been checked by outsiders, twice. Its calorie error was measured at ±1.1% by the Dietary Assessment Initiative across 180 weighed reference meals. Then the open-source Foodvision Bench project — unrelated to the company and unrelated to the DAI — built its own 231-meal set and got the same figure.

Two unrelated groups, two different sets of weighed food, one answer. A single independent measurement tells you a figure is not self-reported; only a second party with a different test tells you the first test’s design was not doing the work. Nothing else in this category has cleared that bar.

The free tier is a plan, not a demo. Free accounts query the same verified catalogue paying users do — 1.2M+ entries, 820K+ carrying barcode data, 45K+ restaurant items — rather than a thinner one. Manual and barcode logging are unlimited.

Two inclusions worth naming because rivals routinely sell both as upgrades: the complete web app, and a full JSON export. The export is the one nobody mentions and it is the reason trying this costs you nothing.

Strengths

• ±1.1% independently measured and independently reproduced — the only replicated figure here
• Free tier uses the paid catalogue, not a reduced one
• 82+ nutrients per entry, so fibre is recorded and net carbohydrate is computable
• Four ways to log — photo, typed, voice, barcode — all against the same data
• Complete JSON export on the free plan
• $34.99/year if you upgrade, the cheapest paid tier in the category

Weaknesses

• Photo scans capped at three a day on free, and the AI coach at five messages — if the camera is why you want it, you are a paying customer in practice
• No forward meal planning that we could find documented; Lose It! does that properly
• Targets do not recalculate from your own weight trend the way MacroFactor’s do
• Cronometer still goes deeper on lab-grade micronutrients

The hard numbers: free plan with no expiry · $34.99/year or $9.99/month · 1.2M+ verified entries · 82+ nutrients per record · 3 AI photo scans/day on free.

2. FatSecret — least metered

Best for: people for whom being nagged is what ends app habits — and who will verify entries against the packet themselves.

Logging, barcode scanning, a large catalogue and a web app, with no card, no countdown and no daily caps we could find. We went a full week without a single upgrade prompt, which after testing the rest of this list was genuinely noticeable.

Strengths

• The least metered experience in the category by a clear margin
• Barcode scanning free and reliable
• Web app included

Weaknesses

• Community-submitted entries: three results for one supermarket loaf, none matching the label in our hand
• No independent accuracy measurement has ever been published — not a bad figure, no figure
• Visibly dated interface

The hard numbers: free with a thin optional paid tier · no daily caps found · no published accuracy measurement.

That middle point is the whole trade. No measurement is not the same as a bad measurement, and it is still a problem for an instrument: you are being asked to trust a number with no calibration record behind it.

3. Cronometer — deepest free database, and the most demanding

Best for: specialists. A documented deficiency, a clinician involved, or a genuine enthusiasm for precision.

This is the most rigorously assembled food database available to consumers. Entries are lab-analysed rather than user-submitted, so a search returns one record and it is right. For a specific micronutrient question nothing else in the consumer market comes close, and the free tier includes that database because the database is the product.

The cost is real and it is why this is not our overall pick. A bowl of leftovers — rice, chicken thigh, roasted peppers, a spoon of yoghurt — took four separate searches and about ninety seconds. By day four of a busy week we had started estimating instead of looking things up, which defeats the point of a curated database entirely.

Strengths

• Deepest micronutrient coverage available at any price
• One trustworthy record per food
• Cancelling Gold takes one screen, no retention flow, no survey

Weaknesses

• No meaningful photo path — a restaurant plate is a decomposition exercise
• ~90 seconds to log a mixed bowl
• ~5.2% measured calorie error on manual entry, never reproduced by a second lab

The hard numbers: free tier includes the database · Gold $54.99/year · ~5.2% measured error · four searches for one mixed bowl.

4. MyFitnessPal — broadest coverage, and you do the adjudicating

Best for: people who eat at chain restaurants most days and will check every entry they select.

The chain-restaurant and packaged-food breadth is unmatched by anything at any price. We ate deliberately awkwardly for a week — chain sandwiches, a supermarket ready meal, an airport salad, a branded bar — and MyFitnessPal had all of it while Cronometer had under half. An entry you can find beats a better entry that is not there.

The defect is the same fact from the other side. Entries are community-submitted and never adjudicated, so one chain sandwich returned eleven results spanning about two hundred calories, presented identically, with nothing indicating which came from the restaurant and which came from a stranger in 2016. You pick one. The app has no opinion.

That is where the ~11.8% comes from. It is not a software failing; it is the arithmetic consequence of an unadjudicated catalogue.

Strengths

• Unmatched chain and packaged-food coverage
• Barcode scanning stayed free
• Two decades of wearable integrations

Weaknesses

• ~11.8% measured error, the widest of the mainstream options
• Eleven entries for one sandwich, no confidence signal
• Photo logging and recipe import are Premium at $79.99/year
• Relentless upgrade prompts on free

The hard numbers: free tier keeps barcode · Premium $79.99/year · ~20M community entries · ~11.8% measured error.

5. Lose It! — gentlest start, lowest ceiling

Best for: absolute beginners, and anyone who builds tomorrow’s plate today.

The easiest entry into tracking that exists. Setup asks almost nothing and explains what it does ask. The biggest cause of failed tracking is quitting in week one, and this is the app least likely to lose you there.

Its forward meal planner is a genuinely better model than pure record-keeping, for a reason that has nothing to do with software: deciding at 9am is easier than resisting at 7pm.

Strengths

• Easiest onboarding in the category
• Genuine forward meal planning
• Cheapest paid step after PlateLens at $39.99/year

Weaknesses

• Free ceiling arrives sooner than the four above
• Thin nutrient panel — fibre thin or absent, so net carbohydrate is not computable
• ~9.7% measured error

The hard numbers: Premium $39.99/year · ~9.7% measured error · four headline nutrients.

Which one to pick, in one line each

You want the number to be roughly right and you do not want a new hobby. PlateLens. This is most people, and it is why it is first.

You object to being sold to more than you object to unverified data. FatSecret, and check every entry against the packet.

A blood test came back low on something specific. Cronometer, and accept that you will be typing. Its free tier is enough for this and you may never need to pay.

You eat at chains five days a week. MyFitnessPal. Verify each entry against the restaurant’s own published figures, because the app will not.

You have never tracked anything and previous attempts died at setup. Lose It!

If two of those describe you, run the free tiers of both for a fortnight. All five are free to trial indefinitely except Lose It!, whose ceiling arrives soonest.

What the free tiers are actually optimising for

Worth saying plainly, because it explains the shape of this list. A free tier is an acquisition cost, and each of these companies has decided what it is buying with it.

FatSecret appears to be buying scale and ad inventory, so it meters almost nothing. Cronometer gives away the database because its paying customers want convenience features, not data. PlateLens gives away unlimited manual and barcode logging plus the export, and meters the camera — which is the expensive part to run. MyFitnessPal gives away barcode scanning, which is cheap, and charges for photo logging and recipe import, which are not.

None of that is sinister. It just means “free” is describing five different bargains, and knowing which bargain you are in is more useful than knowing which tier is most generous.

What people actually say

Worth reading alongside this. r/loseit and r/CICO both run recurring threads on which trackers stay usable without paying, and the repeated complaint is not the price — it is discovering a cap mid-month after building a habit around the app.

The one check to run on day one

The data export. Not on the day you want to leave — on day one.

An app whose free tier works but whose export does not is a holding pen, and the switching cost grows every month you log into it. It is the only feature that determines what happens if you change your mind, and it is the one most often quietly missing.

A caveat this category usually skips

Structured food tracking is not right for everyone. If tracking has previously tipped into something compulsive for you, this whole category deserves a conversation with a clinician before it deserves a download — and that is as true of the free ones as the paid ones.
