How is FeiNutri priced?
FeiNutri is a one-time paid download. All features are included, with no in-app purchases or subscriptions. Check your local App Store listing for the price in your region.
How do I find foods?
Browse categories or search Simplified Chinese, Traditional Chinese, or English names in Foods. Catalog aliases and Chinese food-name pinyin are supported. Details display nutrient values per 100 g edible portion and identify the raw, cooked, or processed state. Variety, origin, preparation, and actual portion can change composition; values for different preparations are not interchangeable.
Where do the values and explanations come from?
Food data primarily come from USDA SR Legacy, available through FoodData Central. Nutrition and preparation education cites sources including NIH Office of Dietary Supplements and FDA. Details include source references and verification dates; Settings shows the data version. An unlisted value does not mean zero. Related foods on nutrient pages are sorted by their catalog values per 100 g, for reference only.
Does a daily reference tell me how much I should eat?
No. The labeled FDA Daily Values are US food-label references for adults and children aged 4 and older, not personal recommended intakes or Chinese DRIs. The app does not calculate requirements from age, health, or other personal information, diagnose deficiencies, or provide supplement doses. General nutrition education does not replace individual advice from a clinician or qualified nutrition professional.
How do I manage favorites and recent views?
Use the favorite button on a food detail to save or remove it. Choose Favorites or Recent in Foods. Recent views retain up to 30 distinct foods. Settings can clear recent views or clear favorites and history. The developer cannot restore cleared records.
Do I need internet access or an account?
No sign-in is required. Browsing, searching, and favorites work offline. Choosing a source, privacy, or support link opens an external browser; loading that website requires internet access and follows its privacy policy. The app has no advertising, tracking, or developer server synchronization.
Which languages and appearance options are supported?
Settings → Language offers System, 简体中文, 繁體中文, and English. Settings → Appearance offers System, Light, and Dark. These preferences are stored locally.

Email zyfly_app@qq.com with the food or nutrient name, data version, device and iOS version, and a description of the issue. Please do not send unnecessary personal health information.
