Common questions
How is Metrical different from other calorie trackers for busy people?
+Most calorie trackers require searching through databases, scanning barcodes, and manually entering quantities. Metrical replaces all of that with a single photo or a quick text description. The entire process takes under 10 seconds, which is the difference between actually tracking and giving up because it takes too long.
Can I track family meals or just individual portions?
+You can photograph your plate from a family meal and AI will estimate the calories for your portion. You don't need to log the entire recipe or calculate servings. Just snap what's on your 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?
+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!
