What is PlateLens?

PlateLens is a calorie and macro tracker for iPhone, Android, Apple Watch and web that logs meals by AI photo, text, voice or barcode. It adds confidence scores, editable portions, adaptive targets and an AI nutrition coach, with a free plan.

PlateLens is a calorie and macro tracking app that lets users log food by photo, typed text, voice, or barcode scan. It runs on iPhone, Android, Apple Watch and in the browser, with one account and one diary shared across all of them. The target user is anyone who wants nutrition tracking without the usual search-and-select routine, from casual dieters to people who track macros closely and want a faster way to do it. In practice, the user points the camera at a meal and an AI vision model identifies each item, estimates portions from plate geometry and food density, and returns a full nutrition breakdown. Every detected item stays editable: ingredients can be split, removed, swapped for a different cooking method, or resized by grams, servings or natural units. Typed or spoken entries such as "150 g grilled chicken, a cup of rice" go through the same analysis, and barcodes are matched against a product database. Nutrient values are drawn from sources including USDA FoodData Central, NCCDB, Open Food Facts, Nutritionix and a restaurant menu set covering 380+ chains. A distinguishing choice is how the app handles doubt. Items receive High, Medium or Low confidence ratings, ambiguous foods show calorie ranges instead of a single figure, and likely hidden oils or sauces are flagged. Beyond logging, the app offers an AI nutrition coach, adaptive calorie targets that recalibrate from intake and weight data, water, exercise and step tracking, and sync with Apple Health and Google Health Connect. It tracks 82+ nutrients and supports English and Spanish. Among alternatives, it competes with search-based trackers such as MyFitnessPal, Cronometer and MacroFactor, and with other photo-first apps. The vendor cites two independent benchmarks reporting about 1.1% aggregate calorie error, while openly noting that this does not cover macros or micronutrients or guarantee any single meal. Comparison figures on the site come from the vendor's own testing, so they deserve some skepticism.

How do you use PlateLens?

1Install the app or open the web version
Download PlateLens from the App Store or Google Play, or sign in through the browser at app.platelens.app. The same account and diary work on every device.
2Set up your profile and goals
Create an account and enter your goals so the app can set calorie and macro targets. The adaptive algorithm later adjusts them from your intake and weight data.
3Log a meal with a photo
Point the camera at a home-cooked, restaurant or packaged meal. The AI identifies each item, estimates portions and returns a nutrition breakdown with confidence ratings.
4Correct and save the result
Tap a detected meal to split ingredients, remove wrong items, change cooking method or adjust portions. Save corrected meals to log them again with one tap.
5Try voice, text and barcode logging
Type or dictate a meal with amounts, or scan a packaged product barcode for database nutrition data. Voice logging also works from the Apple Watch.
6Connect health data and the coach
Sync Apple Health or Google Health Connect for steps, weight and workouts, then ask the AI coach for guidance based on your goals.
