How Global Is the App Store?

67.4% of apps are localised into a single language, and the median app across the whole store supports just 1. For all the talk of a borderless store, the typical app looks like a local business: a regional bank, a national delivery service, a developer building for the users right in front of them. Localisation isn't free. Every added language means translation, testing, and upkeep that never really stops, so for most makers, especially the solo developers who dominate the store, sticking to one language is just the rational call.

Only 10.1% of apps reach ten or more languages, and the ones that get there tend to be the usual names: big platforms, major utilities, blockbuster games, apps built from day one to treat the whole planet as a single market. Localizing that broadly costs real money, so when an app has actually done it, that's worth noticing. Find an app sitting in forty languages and it's telling you something plainly: it has the team and the budget to go global, and it means to use both.

Then there's a smaller, more charming group. These are lightweight apps that translate into far more languages than their size would ever suggest, often because what they do is simple enough that it barely needs translating in the first place. Call them polyglot lightweights. They're some of the quietly impressive apps sitting in the store.

The single-language majority is only half the picture. What happens right after it is the other half. Just 17.5% of apps reach five languages, and only 2.4% reach thirty or more. To find an app offering 10 languages, you'd have to climb all the way to the 90th percentile of the store. For 35 languages, you're looking at the 99th. Most apps simply never bother climbing that ladder. A small, well-funded cluster of developers does all the climbing, while everyone else stays put at the bottom.

The top tier is rare air. Translate Now - AI Translator, the most localised widely-used app we track, ships in 139 languages. Reaching that kind of coverage costs more in translation and testing than most apps even pull in over a year, and almost no independent developer ever gets close.

Language count tells you more about reach than ambition. The relationship tracks audience in an almost straight line. Apps that stick to a single language average 2,743 ratings each, while apps available in thirty or more languages average 35,795, roughly 13 times as many. The share that clears ten thousand ratings (a rough bar for genuine popularity) climbs the same way, from 0.9% of single-language apps to 3.7% of the most localised ones.

Cause and effect run in both directions here, and they reinforce each other. Popular apps can afford to localise widely, and widely localised apps reach more people who might rate them. Either way, the takeaway holds: an app translated into dozens of languages is rarely a small operation, and its rating count usually proves it.

How far an app travels linguistically comes down to what the app actually does. Categories built around visuals rather than words naturally go wider: Photo & Video tops the list, with 31.2% of its apps available in five or more languages, then Graphics & Design at 29.3% and Games at 23.9%. Makes sense, really; a photo editor or a game plays the same regardless of what language is on screen, so adding translations is a cheap way to pick up new users.

Text-heavy, locally-rooted categories sit at the opposite end. Finance barely translates at all, with only 9.9% of its apps hitting five languages, and Food & Drink isn't far behind at 8.1%, with Stickers trailing everyone at 2.3%. If an app is mostly text, or built around one country's restaurants, news, or menus, each new language means real effort for a smaller audience, so a lot of developers just skip it.

Language support sounds like a small detail, but it tells you more than you'd expect. If an app skips the language you actually read in, that's a dealbreaker on its own. Beyond that, the number of supported languages hints at how much resourcing sits behind the app, and whether it's likely to stay maintained across different markets. An app localised into many languages usually has a real team keeping it alive. One offered in a single language can still be excellent, but more often than not it's a smaller, shakier operation. Neither situation is bad by itself. You just want to know which one you're walking into.

We count the number of languages an app declares in its App Store metadata, not the quality of those translations, some "supported" languages are machine-translated menus with an English core underneath. The count also says nothing about which languages: an app in five European languages and an app in five Asian ones look identical here. And a single-language count is not a verdict on quality; plenty of the best apps on iOS serve one market beautifully. Every figure is a plain count over the 1,034,726 apps that declare at least one language.
