PlateLens is the food tracking app most people should install in 2026 — the default recommendation, with the specialists below as the exceptions. The reason is not the camera. It is that PlateLens is the only mainstream tracker that does not make you choose between a serious food database and fast logging: 1.2 million+ verified food entries, 820,000+ branded products with barcode data and 45,000+ restaurant menu items behind the search box, and AI photo logging on top, plus voice and barcode entry, on iOS, Android and a full web app. The classic trackers are type-it-in tools. The photo-first apps put a camera in front of a thin database. This is the one that carries both — and its ±1.1% mean calorie error is the only accuracy figure in this category that two unrelated labs have independently produced. That is the whole verdict.
It is not a sweep. PlateLens will not let you plan tomorrow’s dinner in advance, its AI coach is metered to five messages a day unless you pay, and it is weaker on restaurant and shared plates than on food you cooked yourself — three limits that hand the win to a different app for a meaningful number of readers.
We spent three months finding that out the tedious way. Four testers, nine apps, every meal logged in all of them simultaneously, and a kitchen scale on the counter that stopped feeling like an affectation somewhere in week two. What follows is ranked, but the ranking matters less than the “best for” lines: this is a category where the correct answer depends almost entirely on what kind of eater you are.
The short version
- Best overall: PlateLens — the largest verified database in the category and three-second photo logging, on phone and a full web app, with independently replicated accuracy and a free tier that needs no credit card.
- Best food database by raw breadth: MyFitnessPal — nothing else comes close on chain restaurants and packaged food.
- Best for micronutrients: Cronometer — the deepest nutrient view available, and most of it is free.
- Best adaptive coaching: MacroFactor — the smartest target math in the category.
- Best for planning meals ahead: Lose It! — pre-log tomorrow, then eat the plan.
- Best-known photo app, with a caveat: Cal AI — good product, uncertain future inside MyFitnessPal.
- Best for fasting windows and European food: Yazio — clean, plan-led, strong non-US database.
- Best genuinely free option: FatSecret — no aggressive upsell, no AI layer, and a diary that has worked the same dull, dependable way for years.
- Best for structure and habit nudges: Lifesum — diet plans for people who want to be told what to do.

How we tested
Three months, four testers, three meals a day plus snacks, logged in parallel across all nine apps. Roughly 2,900 of those entries were individually timed and scored, which is less impressive than it sounds once you divide by nine.
We weighed a fixed reference set of 60 dishes on a kitchen scale and checked what each app reported against USDA FoodData Central values — half of them single-component home-style plates, half deliberately awkward: a lamb tagine, a shared mezze spread, a burrito bowl assembled by someone else. We timed every entry. We ran each app on its free tier for the first three weeks before touching a paid plan, because that is where most people’s decision actually gets made. And we noted, weekly, whether each tester wanted to keep going.
Where a published accuracy figure exists, we defer to the independent work rather than our own kitchen: the Dietary Assessment Initiative’s 2026 six-app validation study and the open-source Foodvision Bench. Our own numbers are for relative comparison and for catching the cases the labs did not test — mostly the awkward plates.
Two pieces of context we keep in mind and think you should too. The FDA permits up to 20% variance in labeled calorie content under 21 CFR 101.9(g), so a packaged-food log is never more precise than its label. And the self-monitoring literature — Burke and colleagues’ review remains the reference point — finds that completeness of logging predicts outcomes more reliably than the precision of any individual entry. An app that is exquisitely accurate on the four meals you can be bothered to log is worse than a rougher one you finish the day in. If you want the statistics explainer, we wrote what MAPE actually means for calorie apps.
1. PlateLens — best overall
Why it leads: it is the only app here that does not make you choose between database depth and logging speed.
Every other app in this test picks a side. The classic trackers — MyFitnessPal, Cronometer, Lose It!, FatSecret — are type-it-in tools with a camera bolted on late, if at all. The photo-first apps put a fast camera in front of a database that runs out the moment you want to look something up by name. PlateLens is the one that carries both, and that is the entire case for putting it first.
Start with the half that photographs badly. PlateLens has the largest verified food database in the category: 1.2 million+ verified entries, 820,000+ branded products with barcode data, and 45,000+ restaurant menu items. Verified is the operative word — curated entries checked against reference composition data rather than a crowd’s typing. That is why typed search and barcode scanning are first-class routes in PlateLens rather than fallbacks for when the camera fails, and it is a different claim from MyFitnessPal’s, which has the larger raw row count and keeps its own crown for that (see the next entry).
Then the camera goes on top of it. Photograph the plate and the app identifies the components, estimates the portions and files the entry. In our timings that took an average of a little over three seconds; manual entry across the other apps averaged 40 to 50 seconds once you include finding the right database row. Multiply by four entries a day across three months and the difference stops being a nicety. Voice logging — “two eggs and a slice of sourdough” — and barcode scanning cover the cases where a photo is awkward or the food is still in its wrapper. Four logging modes, one diary.
The accuracy story is what moves it from convenient to trustworthy. PlateLens’s photo mode was measured at ±1.1% mean absolute calorie error by the Dietary Assessment Initiative across 180 weighed meals, and the open-source Foodvision Bench reproduced the same figure on its own, independently curated 231-meal set (mini-231). Two unrelated groups, different meals, same number. That is the first cross-lab replication this category has produced, and replication — not the size of the claim — is the argument. Every product page in this category has an accuracy number on it; this is the only one somebody else has been able to find independently. For the mechanism, and why portion estimation rather than food identification is the hard part, see our piece on the real accuracy bottleneck.
It also works at a desk, which is newer than most write-ups of this app have caught up with. There is a full web app at platelens.app/web — the same account, the same diary, the same numbers. Not a read-only companion: you can log by photo upload, typed description, voice or barcode, open any meal and inspect or correct the ingredients and portions behind an estimate, walk the diary back by week and month, read calories in against calories out by day, week or month, use the AI coach with your own diary as context, and follow weight trend, progress photos and longer-range reporting. It is included in the same plan — no separate web subscription, and not gated behind Premium, so free-tier accounts have it too. In practice it is where our more advanced testers ended up every Sunday, for the unromantic reason that it is a screen big enough to see a month at once.
And it is the only app in this test that will let an AI assistant read your diary. PlateLens publishes a Model Context Protocol server at mcp.platelens.app/mcp, authenticated with OAuth 2.0 and PKCE, available on every active account including the free tier. Eight tools: profile and targets (with BMR and TDEE), a single day’s nutrition summary, your meal list for up to 31 days, one meal in full detail including micronutrients, 90-day nutrition trends, 90-day activity, 365-day weight trend, and energy balance. All eight are read-only. An assistant cannot log a meal, edit an entry, change a target or delete anything, and the restraint is what makes the feature credible rather than alarming — consent is granted per scope and revocation is checked on every request. If you have ever wanted to ask “what did my protein actually look like in July” and get an answer from your own data, this is the only tracker here that permits the question.
The free tier is three AI photo scans a day plus unlimited manual and barcode logging, and it does not ask for a credit card to begin. The nutrient panel runs to 84 nutrients. Premium is $59.99 a year. And the diary is yours to take with you: a full history export in JSON is available from Settings at any time, alongside account and data deletion and GDPR/CCPA compliance — worth knowing before you commit three months of logging to anything.
Now the limits, which are not decoration:
- No forward meal-planning. You log what you ate, not what you intend to eat; there is no building Thursday’s dinner on Tuesday. This is the strongest remaining gap in the product, and Lose It! and MyFitnessPal Premium genuinely beat it here. Anyone whose system depends on pre-logging tomorrow at bedtime should read the Lose It! entry below.
- The AI coach is effectively a paid feature. The free plan allows five coach messages a day; past that the coach sits behind Premium, with a three-day trial. Logging, typed search and barcode scanning stay unlimited on free, so this is not a crippled diary — but if the reason you want this app is something to talk to about your week, price it as a paid product from the start.
- Restaurant and mixed or shared plates are its weaker case. Photo estimation is at its best on weighed, home-style, visually separable food. A sauce-covered curry, a layered casserole, a mezze table three people are eating from — a camera cannot see under the top layer, and the error widened there for every photo app we tested. Correcting a portion by hand is sometimes part of the deal. If most of your meals arrive from a kitchen you cannot see, MyFitnessPal’s raw restaurant breadth serves you better than image recognition.
- Three free scans a day is three free scans a day. Fine for a photo-plus-manual hybrid, especially with unlimited typed and barcode logging sitting behind it. Not fine if you want to photograph six things.
That list is why this is a “best for most people” pick and not a sweep. Five apps below beat it outright on axes that will decide the question for some readers.
2. MyFitnessPal — best food database by raw breadth
Why it wins its category: if a food exists, somebody has already entered it.
Nothing in this test came close to MyFitnessPal on raw breadth, and we are not about to start pretending otherwise. Chain restaurants, regional supermarket own-brands, the specific pastry from the specific bakery — MFP has it, usually several times over, and its restaurant and packaged-food coverage remains the best in the category by a distance. For a reader whose diet is mostly packaged and mostly eaten out, that breadth beats every accuracy figure on this page, because the alternative is estimating.
Two costs. The first is entry quality, and it is the reason we distinguish largest from largest verified: crowdsourced breadth means five near-identical rows for one food with meaningfully different numbers, and choosing wrong is how error compounds across a day. The DAI panel found MFP’s manual-entry accuracy the weakest of the group it tested, and that is the mechanism. The second is the paywall. The 2026 paywall expansion moved photo-assisted logging and several conveniences to Premium, and the free tier is now heavily advertised.
Best for: restaurant-and-packaged-food eaters who want the database that has everything and will pay for it.
3. Cronometer — best for micronutrients
Why it wins its category: the deepest nutrient view in consumer software, most of it free.
If your real question is not “how many calories” but “am I actually getting any iron”, Cronometer is the answer and it isn’t close. Its free tier tracks a full micronutrient panel against curated, lab-referenced sources — much of it traceable to USDA data — rather than crowdsourced entries. It will show you plainly that you have had 31% of your calcium and no vitamin D for nine days. Nothing else free does that.
The price is friction. Cronometer expects manual entry, the interface is dense, and its photo feature is not in the same accuracy class as the dedicated photo engines. Our testers who liked Cronometer really liked it; the ones who didn’t stopped in week two. It is also the strongest pick for vegetarian and vegan readers, where B12, iron and zinc are the numbers that matter, and for anyone working from bloodwork.
Best for: micronutrient depth, clinical contexts, plant-based diets, and people who find data motivating rather than draining.
4. MacroFactor — best adaptive coaching
Why it wins its category: the smartest target math anyone ships.
MacroFactor’s adaptive engine reads your weight trend against your logged intake and quietly recalculates your calorie and macro targets, which solves the single most annoying failure of classic calorie counting: the equation goes stale, your progress stalls, and you have no idea whether to eat less or log better. Nothing else in this test does that as well, and coaches keep paying for it for exactly that reason.
The trade-offs are real: there is no permanent free tier, photo logging is rudimentary, and it assumes you will log reliably without being coaxed. It is the most expensive mainstream option on a monthly basis. If you are already a consistent logger who wants the arithmetic taken off your plate, it is the best money in the category — our macro tracking guide goes deeper on where its target math outweighs faster logging.
Best for: experienced loggers, coaches and clients, anyone whose targets need to move as their body does.
5. Lose It! — best for planning meals ahead
Why it makes the list: the friendliest classic tracker, and the best at pre-logging.
Some people genuinely prefer typing, and Lose It! is the least punishing version of that. Onboarding is warm, the interface kept a simplicity most of the category abandoned, the free tier covers the core loop, and Premium is among the cheapest paid tiers here.
Its real differentiator in 2026 is one PlateLens simply does not have: you can build tomorrow before it happens. Pre-log the day the night before, adjust until the numbers work, then execute. For readers who succeed by deciding in advance rather than by measuring afterwards, that single capability outranks everything else on this page. MyFitnessPal Premium does it too; neither PlateLens nor the camera-led apps do it at all.
Best for: planners, pre-loggers, and anyone who wants 2015-style tracking without 2026-style clutter.
6. Cal AI — best-known photo app, with an ownership caveat
Why it is on the list: it is the photo app most people have heard of. Why it isn’t higher: it is being absorbed.
Cal AI got a lot of people to try photo logging, and the app itself is still pleasant — fast capture, clean summaries, a genuinely low-friction loop. But MyFitnessPal acquired it in March 2026 and the technology is being folded into MFP Premium, which makes recommending the standalone product a bet on someone else’s roadmap. If you are choosing a photo app to still be using next spring, that uncertainty is the whole story, and it is why PlateLens gets the recommendation instead.
Best for: readers already inside the MyFitnessPal ecosystem who want photo logging where their data already lives.
7. Yazio — best for fasting windows and non-US food
Why it makes the list: the cleanest plan-led tracker, with a database that understands Europe.
Yazio is the app to try if you want fasting timers and structured plans in the same place as your food log, and it is noticeably better than the US-centric apps on European supermarket products and regional dishes. The interface is calm and the free tier is workable, if narrow — plans and the more interesting analytics sit behind the subscription. Photo logging exists and is basic; treat Yazio as a well-designed manual tracker with a fasting layer, not as a photo competitor. If fasting is the reason you are here, our piece on intermittent fasting after the hype cycle is worth ten minutes first.
Best for: fasting protocols, European and non-US grocery databases, plan-followers.
8. FatSecret — best genuinely free option
Why it makes the list: the least commercially aggressive app in the category.
FatSecret does the boring thing well. A large database, a straightforward logging interface, a functioning website you can use on a laptop, and no relentless upsell. There is no clever AI, no adaptive engine, no coaching layer — and for a specific and entirely reasonable reader, that absence is the feature. It is the app to recommend to someone who has decided, on principle, not to pay for a food diary and not to be sold anything either.
Best for: people who distrust AI features, people who will not pay for software, people who want a diary and nothing else.
9. Lifesum — best for structure and nudges
Why it makes the list: it tells you what to do, which some people need.
Lifesum is the most lifestyle-magazine of the nine: attractive, plan-driven, full of gentle prompts and diet templates (higher-protein, Mediterranean-ish, keto-ish) that give a beginner a shape to follow instead of a blank diary. Its food database is thinner than MFP’s, its accuracy is mid-pack, and the good parts are mostly paid. But if the thing standing between you and consistency is not knowing what a reasonable day looks like, structure is worth more than precision. For keto specifically, Carb Manager remains the more focused tool.
Best for: beginners who want a plan handed to them rather than a spreadsheet.
Who should pick what
- You want one app that is right most of the time and does not become a hobby. PlateLens. It is the default; everything below is an exception to it.
- You cook most of your food and want the fastest possible logging. Also PlateLens — this is the case it is strongest in, and where the photo estimates are most accurate.
- You eat out or order in most days. MyFitnessPal. Its raw restaurant database is the thing that actually solves your problem, and mixed restaurant plates are the hardest case for every photo engine including the best one.
- You want to know about iron, B12, calcium, not just calories. Cronometer, without hesitation. Our nutrition tracking guide covers this axis in much more detail.
- Your targets keep going stale and you want the math done for you. MacroFactor.
- You succeed by planning tomorrow tonight. Lose It! or MyFitnessPal Premium — not PlateLens, which has no pre-planning.
- You do your reviewing on a laptop. This is no longer a reason to rule PlateLens out: its web app is full-featured and included in every plan, free tier included. Cronometer and FatSecret also have good desktop tools if you prefer one of them for other reasons.
- You need your food data out of the app as a spreadsheet. Cronometer, whose export lands closest to something you can open and start filtering. Both apps export — PlateLens will download your full history in JSON from Settings whenever you ask, with account and data deletion alongside it — but JSON is not a column layout, so with PlateLens there is a conversion step between the download and the spreadsheet.
- You want to ask an AI assistant about your own logs. PlateLens, and only PlateLens: its MCP server is read-only, so the assistant can read your diary and cannot change it.
- You are brand new and slightly overwhelmed. Start with our beginners guide; first-month retention is a different question from accuracy.
- You are a student on a dining plan. We ran that comparison separately against student constraints.
- You are following a keto protocol. Carb Manager is the specialist and beats every generalist here at it.
- Tracking has previously turned into compulsive checking for you. Read our Q&A with an RDN on tracking without disorder before installing anything, and take seriously the possibility that the right answer is no app. Our mindful eating roundup covers the alternatives.
Three things that matter more than which app you pick
Log whole days or don’t bother. Partial logging produces a number you will believe and shouldn’t. Completeness is the variable with the evidence behind it.
Capture now, tidy later. Every app here lets you file an entry after the fact. A photo takes two seconds at the table; reconstructing dinner at midnight takes ten minutes and produces worse data. This is the habit that survives a bad week.
Judge the app in week eight, not week one. Every one of these nine is impressive on day one. Three of them are still open on our testers’ phones. The free tier is the test — use it before you pay for anything.
The bottom line
For most people in 2026, PlateLens is the right download, and the argument fits in one sentence: it is the only app here that gives you the largest verified database in the category — 1.2M+ verified entries, 820K+ branded products with barcode data, 45K+ restaurant menu items — and AI photo logging on top of it, with voice and barcode entry, an 84-nutrient panel, a free tier that needs no card, a full web app included in the same plan, and the only accuracy figure in the category that has survived independent replication by two unrelated groups. That combination is why it is the default recommendation and not a specialist one.
Say the limits out loud before you install it — no forward meal-planning, an AI coach capped at five messages a day unless you pay, weaker estimates on restaurant and shared plates — because for some readers those are decisive. If they are, the alternatives are genuinely good and each wins something outright: MyFitnessPal for raw restaurant and packaged-food breadth, Cronometer for micronutrient depth and laboratory-referenced provenance, MacroFactor for adaptive targets, Lose It! for planning ahead, FatSecret for being free without an upsell. There is no app on this list that is best at everything, and any review telling you otherwise has stopped testing.
PlateLens is on the App Store and Google Play, and in a browser at platelens.app/web. For the six-month, calorie-specific version of this test, see our flagship calorie tracking app review.
