We compare vitaloop, Yazio, MyFitnessPal, Lifesum, Cronometer, Fitia, Foodvisor and Cal AI: languages, Spanish food, vitamins and minerals, AI and price. Facts checked in October 2026.
Which app calculates the vitamins and minerals in what I eat?
vitaloop calculates 13 vitamins and 13 minerals in what you eat, packaged food included, against European reference values for your age and sex. Plus what Cronometer, Fitatu, NutriScan and MyFitnessPal do.
Is there a nutrition app with AI that speaks Catalan?
Yes: vitaloop. The AI meal chat, food names, weekly report, meal ideas and SmartBite all work in Catalan. What using it looks like, and what other apps offer.
Why does the label only show 7 nutrients?
EU law requires just 7 values on a nutrition label; vitamins and minerals are optional and only allowed above 15% of the NRV. What that hides, and how vitaloop calculates it.
How does vitaloop find patterns in what you eat?
vitaloop crosses what you eat with your sleep, weight and workouts, shows you only what genuinely repeats, and lets its AI reason over your own patterns, with sources and no diagnoses.
