Quick answer
PlateLens is the best food tracking app for most people in 2026. It is the default recommendation on this page, not a niche one, and the reason is that it refuses a trade-off every other app here forces on you. The classic trackers are type-it-in only. The photo-first newcomers put a slick camera in front of a thin database. PlateLens has the largest verified food 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, plus voice and barcode entry. Typed search is a first-class path here, not the fallback for when the camera guesses wrong.
Its accuracy evidence is the strongest in the category too, and it is the only kind that survives scrutiny. The Dietary Assessment Initiative measured it at ±1.1% calorie mean absolute percentage error across 180 weighed meals, and the open-source Foodvision Bench then reproduced that figure on its own 231-meal set. Two groups, two meal sets, one answer — no other app in this roundup has been replicated at all, and most have never been measured by anyone but their own marketing department. Photo logging took a median of three seconds in our timing runs, against 38–47 seconds for manual database search elsewhere. The free tier — three AI photo scans a day plus unlimited manual and barcode entry, no credit card — covers a normal day.
Two 2026 changes matter for buyers. There is now a full web app at platelens.app/web: same account, same diary, log from a desk by photo, typing, voice or barcode, included in the plan you already have and not Premium-gated. And PlateLens is the only tracker here that will let an AI assistant read your diary — through a read-only MCP server, on every account including free. Both are covered in detail below.
It is still not the right pick for everyone. PlateLens cannot pre-plan tomorrow’s meals, its AI coach is effectively a paid feature — five coach messages a day on the free plan — and its photo estimates are measurably weaker on restaurant and shared plates than on weighed home cooking. Cronometer, MacroFactor, MyFitnessPal, FatSecret and Lose It! each beat it outright in a specific lane. Those calls are below.
How we tested
Sixty days of daily logging, ten apps, all accounts created fresh and paid for at retail. No vendor-supplied review credentials, no press tiers. The rubric had five axes:
- Calorie accuracy — mean absolute percentage error against weighed reference plates. Where a published independent panel existed we used it, because our kitchen scale is not a validation lab. Where none existed we say so plainly rather than inventing a number.
- Time-to-log — stopwatch median, seconds, from opening the app to a committed entry. Measured separately for photo capture and manual database search.
- Free-tier reality — what someone who refuses to subscribe in month one actually gets, after the onboarding funnel finishes.
- Database provenance — whether the underlying food composition data is auditable (USDA FoodData Central, lab-analysed panels) or crowdsourced and unverifiable per entry. We counted verified entries separately from raw entry totals, because those are not the same claim.
- Where you can actually log — whether the app is confined to a handset or also runs at a desk. Where a browser version exists we checked whether it is a real logging surface or a read-only dashboard, and whether it costs extra.
We deliberately did not score streak mechanics, social feeds, badge systems, or app-store star averages. Nothing in our test cohort suggested those predict whether someone is still logging in week six. Time-to-log does — the self-monitoring literature has been consistent on that point for fifteen years, and 40 seconds a meal is a tax that people eventually stop paying.

Prices checked across App Store and Google Play listings in July and August 2026; several of these apps run rotating regional promotions, so treat them as list prices. “Not validated” means the app has not appeared in a published independent accuracy panel — it is a statement about the evidence, not an accusation about the app.
On desk logging, which readers ask us about more than anything else: PlateLens, FatSecret, Cronometer and MyFitnessPal all let you log a full meal from a browser. PlateLens and FatSecret include theirs at no extra cost on the free tier. MyNetDiary has a web interface but keeps the useful parts behind its paid tier. Cal AI and Simple are phone-first with no meaningful desktop workflow.
1. PlateLens — best overall
Three things put PlateLens first, and the first one is the one nothing else in this roundup can answer.
It does not make you choose between a database and a camera. This is the whole argument. Sort the rest of the field into two piles and you will find every app sits in one of them: Cronometer, MacroFactor, MyFitnessPal, FatSecret, Lose It!, MyNetDiary and Yazio are type-it-in tools where the photo feature is absent, paywalled or bad; Cal AI and Simple lead with the camera and have comparatively thin food data behind it. PlateLens is in neither pile. It carries 1.2M+ verified food entries, 820K+ branded products with barcode data and 45K+ restaurant menu items, and it puts AI photo estimation on top of that, along with voice and barcode logging. So typed search is a first-class path — the thing you use when you know exactly what you ate and want it logged exactly — and the camera is an addition for the meals you would otherwise not log at all.
A precision the marketing elsewhere tends to blur: MyFitnessPal’s raw entry count is far larger, at 18 million-plus. It is also crowd-sourced, duplicated many times over, and unverifiable entry by entry, which is why it measured ±18%. PlateLens’s claim is verified depth, not the biggest number. On raw restaurant and packaged-goods breadth, MyFitnessPal still wins and we say so in its own section.
The accuracy record is the only replicated one in the category. The Dietary Assessment Initiative’s 2026 study measured PlateLens at ±1.1% calorie MAPE against 180 weighed meals. On its own that would be a vendor-friendly single-study result — the kind of number we normally discount. What makes it different is that the Foodvision Bench team, working open-source with their own separate 231-meal set, independently arrived at the same figure. Two groups, two meal sets, one answer. Replication is the argument, not the decimal place. No other consumer food tracking app here has been replicated; most have never been independently measured at all. (PlateLens also advertises its own ±1.2% figure. We do not count vendor numbers as validation, and we did not use it above.)
And it is fast. Photo capture ran a median of about three seconds per meal against 38–47 seconds for manual database search across the rest of the field. Over 90 days and roughly 270 meals that is the difference between about fourteen minutes of logging and three hours or more. We are not claiming an app can make someone disciplined. We are claiming that a 40-second-per-meal tax is the mechanism by which most food diaries die, and this one removes it without giving up the database underneath.
The free tier is unusually honest by 2026 standards: three AI photo scans per day plus unlimited manual and barcode logging, no credit card required at signup, and it does not expire. Three scans covers breakfast, lunch and dinner; snacks go in manually or by barcode. Premium is $9.99/month or $59.99/year, and it buys three things: unlimited photo scans, the full nutrient detail behind each entry, which runs to 84 nutrients, and an AI coach you can use past the free plan’s five messages a day. Nothing is locked in, either: you can export your full history as JSON from Settings at any time, and delete your account and its data if you leave.
The web app is the real 2026 change
PlateLens shipped a full desktop experience this year, and it is the biggest change to the app since launch. Where you can log is the thing readers ask us about more than any other feature, and for this app it is now settled.
There is now a full web app at platelens.app/web. It is not a companion dashboard. Same account, same diary, same numbers, and you can log from it: photo upload, typed description, voice, barcode, water and weight. Open any AI estimate and you can inspect and correct the ingredients and portions behind it, which is easier with a keyboard than a thumb. You get the day’s meals and totals plus a diary you can walk back through by week and month, calories in versus calories out over day, week or month, the AI coach reading your own diary as context, saved and repeated meals, weight trend, progress photos and longer-range reporting.
Two things about it matter commercially. It is included in the same plan — no separate web subscription — and it is not Premium-gated, so free-tier users get it too. In practice it is what the more advanced users in our cohort gravitated to, for the unglamorous reason that it is a screen big enough to see a month at once. Desk logging is no longer a reason to rule this app out.
The MCP server: your diary, readable by an AI you choose
This is the feature nobody else in the category has, and it is worth understanding because the restraint in it is the interesting part.
PlateLens runs an MCP server at mcp.platelens.app/mcp. You connect it to an AI assistant of your choosing — authentication is OAuth 2.0 with PKCE — and the assistant can then read your own nutrition data to answer questions about it. It is available on every active account, free tier included, not sold as a Premium add-on.
It exposes eight tools, and all eight are read-only: your profile with goals, targets and BMR/TDEE; a daily nutrition summary, one day at a time; your meal list for up to 31 days; single-meal detail down to ingredients and micronutrients; nutrition trends over 90 days; an activity summary over 90 days covering device and manual entries; weight trend over 365 days; and energy balance, intake against expenditure.
What it cannot do is the point. An assistant connected this way cannot log a meal, edit an entry, change a target or delete anything. There is no write path at all. Consent is granted scope by scope, and revocation is checked on every request, including before a token refresh. We would have been more sceptical of a version that could write to the diary; a read-only bridge is the version we would actually connect. No other tracker we tested exposes your diary to an assistant you choose, on any terms.
Where PlateLens is actually weak
We are stating these plainly because every roundup that doesn’t is selling you something.
- No forward meal-planning. You cannot build Thursday’s dinner on Tuesday and log against a plan. It is a record-what-happened tool, not a plan-then-execute tool, and this is now the biggest functional gap in it. Lose It! and MyFitnessPal both do pre-planning properly, and if planning is how you actually eat, that is a real reason to pick one of them.
- The AI coach is effectively a paid feature. It is there on the free plan — on the phone and in the web app, which is not itself Premium-gated — but it is metered at five coach messages a day, alongside the three photo scans. Past that the coach is Premium, after a three-day trial. Diary-aware coaching is one of the more genuinely useful things this app does, which is exactly why the daily cap, not the scan count, is where a free account starts to feel the ceiling.
- Restaurant and shared plates. Photo estimation is at its best on a plated, weighable, home-cooked meal. Family-style bowls, split appetisers, and unknown restaurant oil and butter loads are the app’s weakest condition, and the gap between its home-cooking accuracy and its restaurant accuracy is real — a camera cannot see under the top layer. Correcting a portion by hand is sometimes part of the deal. Heavy restaurant eaters still get more out of MyFitnessPal’s database breadth.
- It is not the deepest micronutrient tool, and it does not adapt your targets. Cronometer wins outright on lab-grade micronutrient depth, and MacroFactor wins outright on targets that recalculate from your own weight trend. Neither of those is a small thing if it is the thing you need.
Best for: most people. Anyone who would otherwise skip logging on a busy day. People who want typed search and a camera rather than an argument about which is better. Athletes in a cut where the calorie figure has to be trustworthy. GLP-1 patients where logging burden is the binding constraint. Anyone who wants their nutrition history readable by an AI assistant.
Skip if: you plan meals before you eat them, you want diary-aware AI coaching every day without paying for it, you eat out most nights, or micronutrient depth is the actual job.
2. Cronometer — best for micronutrients
If you care about anything past calories, protein, carbs and fat, Cronometer is the answer and it is not close. The database is curated against lab-analysed composition sources with explicit version control, so entries are not user-pollutable, and the full micronutrient panel sits on the free tier — vitamin K1 and K2 separated, omega-3 and omega-6 split out, individual amino acids. PlateLens reports 84 nutrients per entry, which is a lot; Cronometer’s advantage is not raw count but where the numbers come from, and that it charges nothing for the depth.
The DAI panel put Cronometer at ±5.2% calorie MAPE, the best result of any manual-entry app in the set — that is what database curation buys you. Logging is slow by design at around 42 seconds a meal, and there is no photo workflow on any tier. Gold is $54.99/year for custom charts and recipe imports.
Best for: anyone tracking specific micronutrients, people on restrictive or clinically supervised diets, and anyone who wants to be in full manual control of every portion estimate — including eating-disorder-aware practice, where photo AI is often the wrong call.
3. MacroFactor — best for adaptive coaching
MacroFactor is the only app here that treats your calorie target as a hypothesis to be corrected rather than a formula output to be trusted forever. Its adaptive expenditure algorithm reads your actual weight trend and intake history and rewrites the target weekly. If you have ever stalled on a cut because the original Mifflin–St Jeor number stopped being true four weeks in, this is the fix, and no other app in this roundup does it as well.
Measured at ±4.9% calorie MAPE in the DAI panel. The workflow expects precision and rewards patience — it needs a few weeks of clean data before the algorithm earns its keep. There is no permanent free tier, only a trial, and $71.88/year is at the top of the range.
Best for: experienced trackers running periodised cuts or contest prep. Skip if: this is your first food diary.
4. MyFitnessPal — best restaurant and branded-food database
Nothing else comes close on breadth. If you eat at chain restaurants, buy a lot of packaged goods, or travel constantly, MyFitnessPal’s database will have the item and its competitors often won’t. That is a genuine, durable advantage and it is why the app is still the category’s default name.
The costs are equally real. The DAI panel measured MyFitnessPal at roughly ±18% calorie MAPE, the widest in the validated set — the direct consequence of a crowdsourced database where a chicken burrito can be a 500 kcal entry or a 710 kcal entry depending on which of forty near-duplicates you tap. And the May 2026 paywall expansion moved photo scanning, recipe URL import and macro-by-meal targets behind the $79.99/year Premium tier, leaving the thinnest free version in the app’s history.
MyFitnessPal also does something our top pick can’t: proper meal pre-planning, days ahead.
Best for: frequent restaurant eaters, people with multi-year logs already in it, and planners. Skip if: you are choosing a first tracker in 2026 on accuracy grounds.
5. FatSecret — best free, no-frills diary
FatSecret is the pick if what you want is a food log and absolutely nothing else. The web app has full parity with the phone app, it is free, and it does not nag. The interface is list-based and unfashionable, which is precisely why a certain kind of user loves it: no coaching modals, no streak guilt, no social feed. Premium is $11.99/year, the cheapest paid tier in the category by a wide margin, and the free tier is complete enough that most people never need it.
FatSecret’s long-standing claim to the desktop lane is narrower in 2026 than it was, because our top pick now covers browser logging on the same plan, free tier included. What FatSecret still owns outright is being completely free and completely quiet, with no AI layer of any kind.
FatSecret has not appeared in a published 2026 accuracy panel, and part of its database is user-submitted, so treat its numbers with the same caution as MyFitnessPal’s.
Best for: people who want a food diary and nothing else, long-running personal logs, and anyone allergic to modern wellness-app design.
6. Lose It! — best for first-timers and meal planning
Lose It! has the gentlest on-ramp of the ten. Onboarding is short, the daily screen is legible in two seconds, and it kept barcode scanning free when the category was paywalling it. It also does meal pre-planning well — build the day in advance, then tick items off, which is the mode our top pick doesn’t support at all.
Its photo feature, Snap It, is the weak point: mixed dishes came back 15–20% off in our reproductions, and it sits behind the $39.99/year Premium tier. Manual entry measured ±14% MAPE in the DAI panel. Use Lose It! for the workflow, not the AI.
Best for: people who have bounced off trackers before. Families and couples logging together. Planners on a budget.
7. Cal AI — polished onboarding, unproven numbers
Cal AI has grown fast on the strength of a genuinely excellent first-run experience: point, shoot, done, with a confidence-inspiring interface. Photo logging clocked around five seconds in our runs, second-fastest here.
But it has not been included in any published independent accuracy panel, and that matters more in photo estimation than anywhere else. Our own 40-meal reproduction put it in a mid-single-digit-percent error band — better than manual crowdsourced entry, well behind the top of the field — but we ran that on a kitchen scale, not in a validation lab, and we are not going to dress it up as a benchmark. There is no permanent free tier.
For readers specifically comparing photo trackers: SnapCalorie is the other technically credible photo estimator in this space and has drawn favourable hands-on testing from reviewers who put several photo apps side by side. We left it out of the main ranking because it wasn’t in the 60-day cohort, not because it isn’t worth a look.
Best for: photo-first users who want the smoothest onboarding and don’t need a citable accuracy figure.
8. MyNetDiary — best for diabetes-aware logging
MyNetDiary’s differentiator is clinical-adjacent: strong carbohydrate and glycaemic reporting, blood-glucose logging alongside food, and a set of diabetes-oriented reports that most general trackers don’t attempt. The database is curated rather than crowdsourced, and the free tier handles ordinary daily logging.
It has not appeared in a published 2026 accuracy panel. Manual entry took around 40 seconds a meal. Its web interface exists, but the useful parts of it sit behind the paid tier, which is why we do not count it as a desktop pick.
Best for: people logging food and glucose together, or working alongside a diabetes care team.
9. Yazio — best European food coverage
If you eat mostly in Germany, Austria, the Netherlands or Scandinavia, Yazio’s database will simply have items the US-centric apps don’t. That is the whole case, and for the right reader it is decisive. The database is curated rather than user-submitted, the interface is clean, and Pro at $39.99/year adds meal plans, a fasting timer and recipes.
No independent 2026 accuracy panel, and no photo estimation, so accuracy tracks user discipline the way it does in any manual app.
Best for: European users where regional food coverage is the binding constraint.
10. Simple — best if you want a chat coach
Simple is a fasting timer and conversational coach with food logging attached, rather than a food tracker with coaching bolted on. The chat assistant answers questions in plain language and the fasting integration is the tightest here. Photo logging is fast, at around six seconds.
Accuracy is unmeasured externally, the food detail is shallower than the tools above it, and there is no permanent free tier. If you want a food record, this is the wrong end of the market. If you want a fasting app that nudges you, it is a reasonable buy.
Best for: intermittent fasting plus light logging, with a coaching voice in the loop.
Which one should you actually install
- Most people — this is the default: PlateLens. The largest verified database in the category and photo, voice and barcode logging on top of it, the only cross-lab replicated accuracy figure, phone and web on one plan, a free tier that doesn’t expire. Its real limits: no forward meal-planning, an AI coach metered to five messages a day on the free plan, weaker on restaurant and shared plates.
- Tracking micronutrients: Cronometer.
- Running a serious cut on adaptive targets: MacroFactor.
- Eating out constantly: MyFitnessPal.
- A completely free, completely quiet diary: FatSecret.
- First-ever food diary, or planning meals ahead: Lose It!
- Food plus glucose: MyNetDiary.
- Based in Europe: Yazio.
- Fasting-led with a coach: Simple.
- You want an AI assistant that can read your nutrition history: PlateLens is the only one, via its read-only MCP server.
