Coming soon to TestFlight

Read any Japanese nutrition label.

Point your iPhone at the 栄養成分表示 on a food pack. NutriFacts reads every line, translates it into plain English, and shows each one as a % of daily values.

Everything the label says.
And what it doesn’t.

Scan and read in English

Hold your phone over the panel. NutriFacts finds it, captures it on its own, and translates every line.

See how much is a lot

Japanese labels don’t show daily values. We add them from the guidelines you choose: Japan, the EU, the UK, the US, Canada or the WHO. The UK, US and Canada also say what’s high, in their own words.

Honest about what’s missing

Most labels only list five lines. When sugars or fibre aren’t printed, we say “Not listed”, never zero.

Claims, checked

“糖質オフ” has no legal definition. “カロリーゼロ” means under 5 kcal per 100 g or ml. We say which is which, and check the energy adds up.

Salt, and sodium too

Japan prints salt equivalent (食塩相当量). We convert it to sodium in mg, so you can compare it with home.

Ingredients and allergens

Scan the ingredients box too. See what’s in it in English, with allergens and additives called out.

The carbohydrate breakdown into sugars, starch and fibre, and a check that the numbers add up.
Carbs, broken down. Sugars, starch and fibre, and a check that the energy adds up.

Why it matters

糖質 isn’t sugar.

It’s the most common mistranslation on Japanese packs. 糖質 means net carbs, starch included. 糖類 means sugars. And most labels don’t print either.

NutriFacts shows you exactly how much of the carbohydrate figure the label explains, and how much it leaves out.

Full label36.0 g carbs
