Calvion is a premium AI nutrition app that turns a meal photo into macros in seconds—then tells you what to do next for your goals. Unlike calorie apps that stop at logging, Calvion combines AI photo analysis, barcode/manual entry, hydration, and activity into one Architect Score. Smart Fix learns from your corrections so estimates improve over time. Built for real-world food (local + global cuisine), with a polished Liquid Glass UI and multilingual support. Privacy Mode keeps meal photos.
