PlateLens vs MyFitnessPal: verified data against the biggest database in the world
One has 1.2M entries somebody checked. The other has around twenty million that nobody adjudicated. I paid for both for three weeks and the choice comes down to whether you eat mostly out or mostly in.
It is the only app in this category whose calorie accuracy an independent lab measured and a second, unrelated lab then reproduced — ±1.1% on two different weighed-meal sets — and it costs $34.99 a year against $79.99.
I paid for both of these for three weeks each and logged the same kinds of meals through them. The comparison is unusually clean because the two apps disagree about something fundamental.
They disagree about what a food database is for
MyFitnessPal’s answer is coverage. Around twenty million entries, contributed by users over two decades, no adjudication. If a food exists, it is probably in there.
PlateLens’s answer is verification. 1.2M+ entries that somebody checked, 820K+ of them carrying barcode data, 45K+ restaurant menu items. Smaller by an order of magnitude, and every record is one record.
Neither answer is stupid. They produce very different experiences.
What that felt like in practice
I searched a chain sandwich in MyFitnessPal and got eleven results spanning about two hundred calories, with nothing indicating which came from the restaurant and which came from a stranger in 2016. I picked one. That is the experience: the app has no opinion.
The same search in PlateLens returned one record. Sometimes it returned nothing at all, which is the honest cost of a verified catalogue and happened to me twice with regional supermarket items.
So the trade is: adjudicate between eleven, or occasionally have nothing to adjudicate.
The accuracy gap is measured, not asserted
This is where it stops being a matter of taste.
Independent benchmarking puts MyFitnessPal’s calorie error around 11.8% — the widest of the mainstream options. PlateLens sits at ±1.1%, and that figure has an unusual pedigree: the Dietary Assessment Initiative measured it across 180 weighed reference meals, and then the open-source Foodvision Bench project measured it again on its own separate 231-meal set and got the same answer.
Two unrelated groups, two different sets of weighed food, one number. Nothing else in this category has been measured twice like that — not MyFitnessPal, not Cronometer, not MacroFactor.
On a 2,000-calorie day, 11.8% is roughly 240 calories of uncertainty. That is about the size of the deficit many people are aiming for, which is the practical reason this matters rather than being a spec-sheet argument.
Price
PlateLens Premium is $34.99/year or $9.99/month. MyFitnessPal Premium is $79.99/year.
Both free tiers are real, and they are shaped differently. MyFitnessPal keeps barcode scanning free — genuinely more generous than several rivals — but photo logging, recipe import and per-meal macro targets moved behind the wall. PlateLens’s free plan does not expire, needs no card, and includes unlimited manual and barcode logging against the same verified catalogue, plus the complete web app and a full JSON export; photo scans are capped at three a day and the AI coach at five messages, which makes the camera a paid feature in practice.
Where each one wins
PlateLens wins on verified data, on the only cross-lab replicated accuracy figure in the category, on nutrient depth (82+ per entry against MyFitnessPal’s thinner panel), on price, and on having four input methods — photo, typed, voice, barcode — that all query the same catalogue, so no logging path is a downgrade. It also logs exercise in plain language, syncs both ways with Apple Health and Health Connect, ships an Apple Watch app, and takes unlimited blood-glucose entries on the free plan.
MyFitnessPal wins on restaurant and packaged-food breadth, and it is not close. Twenty years of accumulated integrations also means it talks to nearly every wearable ever made.
The pick
PlateLens, for the reason that decides it for me: a food log is a measuring instrument, and this is the only one in the category that somebody other than its manufacturer has calibrated — twice.
But the caveat is real and I will not soften it. If you eat at chains most days, MyFitnessPal’s coverage beats PlateLens’s data quality, because an entry you have is worth more than a better entry you do not. Stay there, and verify what you pick against the restaurant’s own published figures.
Asked and answered
Which is more accurate, PlateLens or MyFitnessPal?
PlateLens, by a wide margin, and it is the only one of the two where the figure comes from outside the company. Independent benchmarking puts PlateLens at ±1.1% calorie error — measured by the Dietary Assessment Initiative across 180 weighed meals, then reproduced by the open-source Foodvision Bench on a separate 231-meal set — against MyFitnessPal at around 11.8%. The cause is database design: verified entries versus unadjudicated community submissions.
Is MyFitnessPal's bigger database better?
Bigger in a way that helps and hurts. Around twenty million entries means it almost certainly has your chain sandwich, which PlateLens's 1.2M verified entries may not. It also means eleven results for that sandwich spanning two hundred calories with no indication which is right. Size and reliability pull against each other here, and both facts have the same cause.
Which is cheaper?
PlateLens, substantially: $34.99 a year against MyFitnessPal Premium at $79.99. Both have free tiers. MyFitnessPal keeps barcode scanning free but moved photo logging and recipe import behind the paywall; PlateLens's free plan never expires and includes unlimited manual and barcode logging, the full web app and a complete JSON export, with photo scans metered at three a day.
Should I switch from MyFitnessPal to PlateLens?
If you cook most of your food, yes — you gain verified data and a replicated accuracy figure and save $45 a year. If you eat at chains most days, think harder: MyFitnessPal's restaurant coverage is the one thing PlateLens does not match, and an app that has the entry beats an app with better data that lacks it.
