🇺🇸Sarah J.

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.
🇬🇧Michael R.

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.
🇨🇦Emily L.

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.
🇦🇺David K.

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.

Between 12-hour study sessions and hospital rotations, I have zero time for complex apps. Metrical lets me stay on top of my nutrition without any mental overhead. Game changer.

Switched from MyFitnessPal after 3 years and never looked back. No ads, no premium upsells, and the AI understands meals in Spanish perfectly. Exactly what I needed for race prep.
🇺🇸Rachel T.

The no-account-needed approach is genius. I opened the app for the first time and was tracking within seconds. No email, no password, no BS. Just food logging that respects my time and privacy.

How does Metrical ensure my food tracking data stays private?
Metrical uses a local-first architecture where all data is stored on your device. There are no user accounts on our servers, no cloud sync, and no server-side data processing. Your meal logs, calorie counts, and nutrition data physically cannot be accessed by us or anyone else because they never leave your phone or browser.
Does Metrical sell or share my dietary data with advertisers?
Absolutely not. Metrical has no advertising, no analytics tracking, and no data partnerships. We do not collect your data in the first place, so there is nothing to sell or share. Your food diary is yours alone, stored on your device, invisible to everyone except you.
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!
