Metrical shows you nutrition information without labels like "good" or "bad." There are no red warnings when you exceed a number, no guilt mechanics, and no streaks that punish you for missing a day.
The goal is to understand your eating patterns, not to control every calorie. Over time, you naturally learn portion sizes and nutritional content without needing to log everything forever.
There is no pressure to log every single meal. Track when it feels right, skip when it doesn't. No broken streaks, no notifications nagging you to log, no penalties for taking a break.
Forget about food databases! AI identifies and estimates calories automatically
Capture meals with your camera or just describe them in natural language
Your data stays on your device with easy import and export options
Optimized for speed with a minimalist interface for quick tracking
Start tracking immediately, no account creation needed
Available in English and Spanish (more languages coming soon!)

Finally an app that doesn't make me overthink meals. I snap a photo of my plate and forget about it. My clients love it too: zero learning curve and no annoying sign-up screens.
Software engineer
As a developer, I appreciate the privacy-first approach. No account, no cloud, all data stays on my device. It's also insanely fast: I log lunch in literally 5 seconds flat.
Nutritionist
I recommend Metrical to clients who struggle with food diary fatigue. It promotes mindfulness without obsession, exactly what I want from a tracking tool in my practice.
Personal trainer
I've tried every calorie app out there. Metrical is the only one my clients actually stick with because it's so quick. The AI photo detection is surprisingly accurate even with homemade meals.

Yes, when done right. Metrical is designed for gentle awareness, not rigid control. It helps you understand what you eat without assigning moral value to food choices. Many mindful eating practitioners use light tracking as a tool for building food awareness that eventually becomes intuitive.
Metrical is specifically designed to avoid obsessive patterns. There are no streaks, no warnings when you go over a number, and no pressure to log every meal. It is a tool for awareness that you can use as much or as little as feels healthy for you.
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!
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.
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.
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.
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.
