Who PlateLens is for

Almost everyone who wants to count calories without making it a second job. The app’s design idea is simple: every meal should have a fast, accurate way in. A packaged snack is a barcode scan. A dinner plate is a photo you confirm. A coffee is a sentence said out loud. Your usual breakfast is a saved meal. Most trackers are excellent at one of those and awkward at the rest; PlateLens is good at all of them, and they all land in the same diary.

Setting up

Setup takes a few minutes. You enter your height, weight, age, sex, activity level and goal, and PlateLens builds a daily calorie target and macro targets from them. You can keep the suggested split or set your own percentages. Connecting Apple Health on iPhone or Health Connect on Android brings in steps, workouts and weight, and sends your nutrition back the other way so other apps can use it.

From there the diary shows the day’s calories and macros against your targets, alongside water and your weight trend.

Logging

Photo. Point the camera at a plate and PlateLens identifies the foods and estimates portions. When it is unsure, for example whether the rice is white or cauliflower rice, it asks instead of guessing. You can open any entry to see the ingredients and amounts behind the estimate and change them.

Barcode. The scanner draws on more than 820,000 branded products with barcode data, so packaged food comes in with the label’s numbers.

Voice and typed search. Say or type what you ate and the entry is matched against 1.2 million verified foods. Because the database is verified rather than crowd-sourced, you are not choosing between six versions of the same yogurt with six different calorie counts.

A day of logging, step by step

The best way to understand the app is to walk through an ordinary day.

• Breakfast at home. Your usual oats with banana and peanut butter was saved as a meal on day one, so it is one tap.
• A coffee on the way to work. You say “large flat white with oat milk” and the entry appears, matched against the verified database.
• Lunch from a café. You photograph the plate. PlateLens identifies the grilled chicken, the grain salad and the dressing, estimates each portion and, if it cannot tell whether the dressing is a vinaigrette or a creamy one, asks. You check the portions and save.
• An afternoon snack. You scan the barcode on a protein bar and the label’s numbers come in.
• Dinner from a recipe. You cook a curry you make often, built once in the recipe tool, and log your bowl.

Five meals, five different ways in, one diary. That is the point of the app: no meal is the awkward one you skip.

The food database

Most of a calorie tracker’s accuracy comes from its food data. PlateLens’s database is verified rather than crowd-sourced: more than 1.2 million foods, more than 820,000 branded products with barcode data and more than 45,000 restaurant menu items. In practice, that means one clear entry for a food instead of a list of near-duplicates with different numbers.

Nutrients, macros and net carbs

Each entry carries 82+ nutrients: the macros, fiber and sugar, and a long list of vitamins and minerals including sodium, potassium, iron and magnesium. For low-carb and keto eaters, every meal shows total carbs, net carbs (calculated automatically as total carbs minus fiber and sugar alcohols), fiber and sugar, and a macro view shows the day’s fat, protein and net carbs in grams and as percentages. People who want to watch a particular nutrient, such as iron on a vegetarian diet or sodium for blood pressure, can see it without leaving the main diary.

The AI coach

PlateLens includes an AI coach you can message with questions about your eating and your goals, for example what to have for dinner to reach a protein target or how to fit a restaurant meal into the day. The free plan includes 5 messages a day; Premium makes them unlimited.

Beyond the food log

PlateLens has quietly become the hub of a health routine. It logs water and weight with a trend line and progress photos, and its adaptive TDEE turns those weigh-ins into a better calorie target over time. It records blood glucose readings, typed in or synced from your meter or sensor app, and shows them next to your meals and workouts. It tracks alcohol, plans meals ahead with grocery lists, and runs an intermittent-fasting timer on the free plan. Its 3D Body Scan turns 12 phone photos into waist, hip and chest measurements, which is useful when the scale stalls but your shape is changing.

Fasting and glucose

The intermittent-fasting timer is on the free plan, with 16:8 and 14:10 presets, custom windows, reminders and a home-screen widget. Because it sits in the same app as the food diary, your eating window and your meals are in one place.

Blood Glucose logging is free and unlimited. You can type readings in, in mg/dL or mmol/L, with the meal context and sample type, or sync them from your meter or sensor app through Apple Health or Health Connect, where the sensor app stays the source of truth. The diary places each day’s readings on a timeline with your timed meals and exercise beside them as context, and the analysis view summarises 7, 30 or 90 days. It is designed to show what you observed honestly: one reading is one point, sparse data is labelled as limited, and a summary around meals only appears once there are enough repeated readings to say something.

Meal planning, recipes and alcohol

The recipe and meal planner lets you plan meals ahead, including low-carb ideas, and turns the plan into a grocery list. Recipes you build are saved for one-tap logging. Alcohol is tracked alongside the rest of your nutrients, so you can see what share of a week’s calories came from drinks.

Platforms and data

The same account and diary run on iPhone, Android and a full web app at platelens.app/web, included on every plan. It syncs both ways with Apple Health and Health Connect, exports your whole history as JSON from Settings, and offers a read-only MCP server so an AI assistant you choose can read your diary with your consent, without being able to change it. The app is available in English and Spanish.

Privacy and your data

Your data stays yours. You can export your full history as JSON from Settings at any time, and delete your account and data. The read-only MCP server works only with an assistant you choose to connect, and it can read but never change your diary. 3D Body Scan images are deleted after processing and are not used for training.

Price

The free plan never expires and covers what most people need. Premium costs $34.99 a year or $9.99 a month and removes the daily limits on photo scans and AI-coach messages. That is less than Lose It! Premium ($39.99), Cronometer Gold ($59.99), MacroFactor ($71.99) and MyFitnessPal Premium ($79.99).

Who will get the most from it

• First-time trackers, because the free plan covers the whole routine and the fastest method is always available.
• Busy people who eat out, cook and snack in the same week and need every kind of meal to be quick to log.
• Low-carb and keto eaters, for the automatic net carbs and macro view.
• People logging glucose readings alongside their meals.
• Spanish speakers, with the full app in Spanish.
• Anyone moving from an older tracker who wants verified food data and a lower Premium price.

How to start

1. Install PlateLens on your phone or open the web app, and set your goal.
2. In the first week, log everything without changing it, and save your regular breakfasts and recipes.
3. Connect Apple Health or Health Connect so weight and activity flow in.
4. From the second week, let the adaptive target and the weekly view guide small changes.
