The Languages the App Store Forgets

Look at any app that bothers with localization at all, and 93.9% of them will include English. It's the default a developer reaches for first, no matter where they're based, and nothing else comes close. After English, coverage drops fast. Even the largest European and East Asian markets only land in the 20 to 30% range, and everything else falls behind that. For a store used on every continent, the linguistic center of gravity stays surprisingly narrow.

Rank the world's languages by native speakers and match each to its app coverage, and the gap is stark. Chinese, with around 940 million native speakers — more than any other language — appears in just 17.4% of apps. Bengali has roughly 234 million speakers yet reaches only 0.8%. The pattern repeats across South Asia especially: Hindi, Bengali, Punjabi, Urdu, and the major Indian languages command enormous populations and minimal app support. Of the ten most-spoken languages on the planet, only 1 is localized in more than half of apps.

Revenue drives this, not headcount. Developers follow the money, and App Store revenue clusters in the US, Western Europe, Japan, and a handful of other markets. Storefronts tied to those regions tend to get localized first, while languages spoken by billions of people in lower-revenue markets end up waiting. Translation, testing, and upkeep all cost real money, which is why smaller and solo developers usually build for one audience rather than several. The store's language map ends up tracking GDP more closely than it tracks population.

The coverage numbers hint at a blunter truth: most apps never bother going multilingual. 66.2% of the apps that declare a localization ship in exactly one language, 591,208 of them, and 93.8% of those single-language apps speak only English. Add it up and 62% of the entire set offers English and nothing else. For most apps, English isn't a starting point, it's the whole offer. If you can't read it, that chunk of the store just stays closed to you.

Coverage drops off a cliff right after English. Developers add English first, and for most solo makers and small studios, that's where the effort ends too. Every other language on the chart is left fighting over the small group of apps that actually pushed through a second, third, or fourth translation.

Nowhere does the gap widen quite like it does on the Indian subcontinent. Add up its eight major languages, Hindi, Bengali, Punjabi, Telugu, Marathi, Tamil, Urdu, and Gujarati, and you're looking at roughly 1,064 million native speakers, a bigger bloc than any other language on this chart. Yet their average app coverage sits at just 1%. Hindi leads the pack and still only shows up in 3.7% of apps. Gujarati brings up the rear at 0.4%.

Set that against a mid-size European language and the mismatch jumps out. German has around 76 million speakers but appears in 16.9% of apps, more than four times what Hindi manages despite having 345 million speakers behind it. Speaker count clearly isn't calling the shots here. Market revenue is. You won't find a wider gulf anywhere else in the store between how many people speak a language and how many apps bother to speak back to them.

Two honest limits apply here. First, listing a language isn't the same as supporting it well. An app can declare a localization and still hand you a thin or machine-translated version, so this data only tells you whether a localization exists, not how good it is. Second, coverage counts apps, not people using them. One heavily used app that supports a given language can matter more to real users than a hundred smaller apps that skip it entirely. Every figure here comes from a direct count across the 893,699 apps that declare any localization, nothing here is modelled, but a language's real reach still depends on which apps carry it, not just how many do.
