FAQ
Common questions
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.

+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.

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?
