One-Tap Photo Logging

Open Metrical, tap the camera button, and snap your meal. The AI analyzes your photo, identifies each food item, estimates portion sizes, and returns a full calorie and macronutrient breakdown before you even sit down to eat.

🍽️

Works With Any Meal

From a simple sandwich to a complex restaurant plate with multiple dishes, the photo recognition handles it all. It works with home-cooked meals, fast food, salads, smoothie bowls, and everything in between.

Detailed Breakdown From a Photo

Each photo scan returns not just total calories but a complete macronutrient profile including protein, carbohydrates, and fat. You get the same nutritional detail as manual logging but in a fraction of the time.

❓ FAQ

Common questions

How does photo calorie counting work in Metrical?

When you take a photo of your meal, Metrical's AI vision model analyzes the image to identify individual food items, estimate portion sizes based on visual cues like plate size, and calculate the nutritional content of each component. The entire process takes just a few seconds and returns calories, protein, carbs, and fat for the complete meal.

Does photo calorie counting work for restaurant meals and takeout?

Yes. The AI is trained on a wide variety of food images including restaurant dishes, takeout containers, fast food, and cafe meals. It handles multi-component plates, mixed dishes, and cuisine from around the world. For best results, take a clear, well-lit photo showing the full plate.

Is it truly free?

Completely free with all features included. No premium tiers, no hidden costs, no ads. Every feature is available from day one. Give it a try!

Do I need to create an account?

No. Metrical requires zero sign-up. No email, no password, no account creation. You open the app and start tracking immediately. We believe nutrition tools should have zero barriers to entry.

Where is my data stored?

All your data stays 100% on your device. Nothing is sent to our servers: no food logs, no photos, no personal information. You own your data completely, with easy export/import options if you switch devices.

How accurate is the AI?

Works best with common foods and workouts. Include details like '100g Greek yogurt' or 'grilled chicken breast with rice' for better estimates. The AI improves with each update, and rough consistent tracking is far more valuable than perfect occasional logging.

How is this different from MyFitnessPal?

Metrical uses AI to estimate calories instantly from photos or text descriptions, no searching through databases. It's designed to be 10x faster, completely private (no account, local data only), and 100% free with no ads.

Does it work offline?

Yes! Once loaded, Metrical works fully offline. Your food logs, history, and stats are all stored locally on your device. You can track meals anywhere without an internet connection.

Can I track macros (protein, carbs, fat)?

Absolutely. The AI automatically estimates macronutrients for every meal. You can also set custom macro goals and track your daily progress against personalized targets.

Is it available on iOS and Android?

Metrical is a progressive web app (PWA) that works on any device with a browser. On iOS, you can add it to your home screen from Safari for a native app-like experience. No app store download needed!
