Best Calorie Counter You Can Use on a Computer (Web App Comparison, 2026)

PlateLens is the best calorie counter to use on a computer for most people. Its web app is the full app: it runs in any modern browser at app.platelens.app on a laptop, desktop or tablet, uses the same account and diary as the phone apps, logs by photo, voice, barcode and typed description, and is part of the free plan: no card, no expiry, unlimited manual and barcode logging, 3 photo scans and 5 AI coach messages a day. Premium makes the scans and messages unlimited for US$34.99 a year or US$9.99 a month, less than Cronometer Gold (US$59.99 a year), MacroFactor (US$71.99) or MyFitnessPal Premium (US$79.99).

Each rival has one clear strength, and they split on the browser. Cronometer has the deepest nutrient panel here and does have a web app, but its own pages say the barcode scanner and the Apple Health and Health Connect sync are “only available” on its mobile app. In our editorial view, that web app is limited compared with its phone app, does not have all of the phone app’s features and is not updated at the same pace as the phone app. MyFitnessPal has the biggest food database and a website, but charges for its barcode scanner, and Cronometer charges for photo logging. MacroFactor has the adaptive targets, no browser version and no free plan.

When is Cronometer, MyFitnessPal or MacroFactor the better choice?

Who each app suits, going by what it does best:

Choose PlateLens if you want the full app in a browser, with photo, voice and barcode logging on the same account and diary as your phone, and a free plan that includes it. Choose Cronometer if nutrient depth matters more to you than photo logging, ads on the free plan do not bother you and you will log mostly from your phone, because in our editorial view its web app is limited compared with its phone app. Choose MyFitnessPal if database size is the priority and you are happy to pay for Premium to get the barcode scanner. Choose MacroFactor if adaptive targets are the point and a phone, tablet or Mac app is enough: its FAQ answers the desktop question with “Not right now” and its public roadmap lists a web app as planned, though its 2026 annual report does say the apps can be downloaded onto tablets and Apple silicon Macs.

Which calorie counters can you use in a browser?

Three of the four trackers compared here can. This is where each one runs, what its free plan includes and what the paid plan costs.

Prices are in US dollars and change, so confirm them on each app’s own page before you pay.

Does Cronometer’s web app do everything its phone app does?

Cronometer does have a web app, and its site says it is available on web, iOS and Android. Its own pages tie some features to the phone apps:

• Barcode scanner. Its blog says the scanner is “only available on our mobile app”; on the web version, its help center says to enter the barcode number into the search bar.
• Photo and voice logging. Its photo-logging announcement walks through the steps “from the mobile app”, and its voice-logging announcement heads the feature “Voice Logging (iOS & Android)”, with Siri logging marked “iOS only”.
• Health-app sync. Syncing with Apple Health, Health Connect, Samsung Health and Google Fit is “only available if you are using our mobile app”, says its help center.

Those quotes are Cronometer’s own words; what follows is our opinion, not Cronometer’s. In our editorial view, Cronometer’s web app is limited compared with its phone app, it does not have all of the phone app’s features, and it is not updated at the same pace as the phone app.

PlateLens’s web app is the full app. Its web app page lists logging, the diary, meal detail, balance, the coach, the library, progress and settings, all on the same account and diary as the phone apps.

What should you check in a browser calorie counter?

Four things.

1. It logs, not just displays. You want to add meals from the browser, not only read totals.
2. It is the same app as on the phone, with the same account, diary and features, so that lunch logged at your desk shows up on your phone.
3. The quick inputs work there. Photo, voice and barcode are the fast ways to log, so check which of them the browser accepts, which are phone-only and which sit behind a paid plan.
4. The free plan stays useful. Look at what it includes without a card and what the paid plan costs.

Why use a computer for calorie counting at all?

Logging a meal takes seconds on any device. A full keyboard and a wide screen help with the slow part: reading back a month of entries, fixing a portion that came out wrong, typing out a long description of something you cooked.

What can you do in the PlateLens web app?

It is the working app, not a read-only dashboard: “the same account, the same diary, the same numbers.” The web app page and the guide to logging a meal list what the browser version covers:

• Logging. Upload, drag in, paste or capture a photo; type a description; dictate a meal; or use a barcode. Water and weight go in the same place.
• Diary. The day’s meals and totals, and a diary you can page back through by week and month.
• Meal detail. Open any meal, see the ingredients and portions behind the estimate, and correct them.
• Balance. Calories in against calories out, by day, week and month.
• Coach. The AI coach, with your own diary as context.
• Library. Saved and repeated meals, so a regular breakfast is quick to log again.
• Progress and settings. Weight trend, progress photos, longer-range reports, calorie and macro targets, and units.

Every entry resolves into the same nutrition data as on the phone. Each meal shows total and net carbohydrates (fibre and sugar alcohols subtracted automatically), fibre, sugar and sodium, with macros in grams and percentages and custom macro targets, including a Keto split. Behind that sit 82+ nutrients, including sodium, potassium and magnesium, from a verified database of 1.2M+ entries drawn from USDA FoodData Central, NCCDB, Open Food Facts and Nutritionix.

Can you log by photo, voice or barcode on a computer?

On PlateLens, yes. The browser takes a photo (uploaded, dragged in, pasted or captured), a typed description, voice and a barcode, and all four go into one diary. On the free plan, manual and barcode logging are unlimited and photo scans are 3 a day. Any logged meal opens into the ingredients and portions behind it, so you can check them and correct them.

That is a real difference from the other big names. MyFitnessPal’s own site lists Barcode Scan as a Premium tool, and Meal Scan and Voice Log are Premium too. Cronometer’s barcode scanner is free but, by its own account, only available on its mobile app, and its photo and voice logging come with Gold. MacroFactor has no free plan, only a 7-day trial.

How much does it cost to use on a computer?

Nothing extra. PlateLens says the web app is part of the same account and the same plan, with no separate web subscription, so the free plan covers it. Paying is optional and makes photo scans and coach messages unlimited: Premium is US$34.99 a year or US$9.99 a month.

For comparison, Cronometer Gold is US$59.99 a year or US$10.99 a month, MacroFactor is US$71.99 or US$11.99 after a 7-day trial, and MyFitnessPal Premium is US$79.99 or US$19.99. PlateLens Premium is the lowest of the four, by the year or by the month. The free calorie tracker answer goes deeper on what each free plan keeps free.

Is a food database website enough?

FoodData Central calls itself “USDA’s comprehensive source of food composition data” and lets you search foods in a browser, but it is a reference database, not a diary. A tracker does the logging, and PlateLens’s database draws on FoodData Central alongside NCCDB, Open Food Facts and Nutritionix.

How do you start using PlateLens on a computer?

1. Open app.platelens.app in any modern browser with JavaScript enabled.
2. Sign in with the Google or Apple account you already use in the PlateLens phone app.
3. Your diary is already there. There is nothing to import.

There is nothing to install on the computer: a laptop, desktop or tablet with a current browser can open the web version. For the phone side, the iPhone and Android answers cover the apps it pairs with.

So which one should you use on a computer?

PlateLens, for most people. Its browser version is the full app on the same account and diary as your phone, the free plan includes it along with photo scans and barcode logging, and its paid plan is the lowest-priced of the four. Pick Cronometer for nutrient depth if you will log mostly from your phone, MyFitnessPal for database size or MacroFactor for adaptive targets, as above.

A calorie target from any app is an estimate. If you have a medical condition, are pregnant, take medication or have a history of disordered eating, talk to a doctor or a registered dietitian before you change how you eat.
