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.

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?
+Yes! Metrical is completely free with all core features included: AI meal analysis, photo recognition, macro tracking, insights, and more. No ads, no data selling. The optional Cloud plan ($29.99 one-time) adds cross-device sync, automatic backups, and enhanced AI.
Do I need to create an account?
+Not for the free version. Metrical requires zero sign-up: you open the app and start tracking immediately. If you upgrade to Cloud, you sign in with just your email (magic link, no password needed).
Where is my data stored?
+On the free plan, all your data stays 100% on your device. Nothing is sent to our servers. With Cloud, your data is encrypted and synced securely, but a local copy always remains on your device as an offline backup.
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. Cloud users get access to our enhanced AI model for even better accuracy.
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, and has a generous free tier with no ads.
What does Cloud include?
+Cloud is a one-time $29.99 payment that gives you lifetime access to: cross-device sync (use Metrical on your phone, tablet, and computer), automatic cloud backup, enhanced AI analysis with a more powerful model, and advanced long-term insights and trends.
Is Cloud a subscription?
+No! Cloud is a one-time payment of $29.99. You pay once and get lifetime access. No recurring charges, no surprise fees.
Does it work offline?
+Yes! Both Free and Cloud work fully offline. Your food logs, history, and stats are stored locally on your device. Cloud users get automatic sync when back online.
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. This works on both Free and Cloud.
Is it available on iOS and Android?
