Readlang app download: what actually exists for each device

Why there is nothing to download

Readlang has been a web application since it launched in 2013. You sign in at readlang.com, your texts and your word list live on the server, and the reader runs in whatever browser you happen to open. The founder's own instructions for phones, posted on the Readlang forum in June 2024 under the title "Install Readlang on your iPhone, iPad or Android home screen", describe exactly that: open the site, add it to the home screen, done.

A native app is one of the most requested things on that forum. There are threads called "Native mobile app?" from June 2025 and "Readlang App possibility" from March 2026, and separate threads asking for offline reading in November 2024 and October 2025. As of September 2026 none of it has shipped. The whole guide to the product is on the Readlang page; this one only answers the download question.

The question arrives in every language. "Télécharger Readlang", "Readlang indir", "Readlang скачать", "readlang install", "readlang app store": all of them lead to the same place. There is no installer, no APK, no .exe and no .dmg: a browser extension for computers, a shortcut for phones. That is how the product is built, and it has a real upside: nothing to update and one login everywhere.

Device by device: what you install and what you get

Every row below is the same website reached a different way. The right-hand column is what changes in practice.

Checked against readlang.com and the official Readlang forum on 14 September 2026.

Two things are the same on every row: translation happens on Readlang's servers, so nothing works offline, and your account, uploads and word list are identical wherever you open the site.

iPhone and iPad: add the site to the home screen

This is the official route, and it takes under a minute.

1. Open Safari, go to readlang.com and sign in.
2. Tap the Share button at the bottom of the screen.
3. Scroll the sheet and tap Add to Home Screen.
4. Keep the name Readlang or shorten it, then tap Add.

The icon opens the site full screen with everything your account already has. For other websites, Readlang publishes a Safari bookmarklet instruction; there is no Safari extension. What the home-screen version feels like day to day, and where it runs out, is on the Readlang on iPhone page, so it is not repeated here.

Android: a shortcut, or Firefox with the extension

Android has two official routes rather than one, and the second is the better one for reading the open web.

1. In Chrome, open readlang.com, sign in, tap the three-dot menu and choose Add to Home screen. This is the same full-screen website as on an iPhone.
2. Or install Firefox for Android, add the Readlang Web Reader extension from addons.mozilla.org, and any page you open in Firefox becomes clickable. The Readlang forum calls this by far the easiest method on Android.

Both routes, the steps for each, and the question of APK files are covered in full on the Readlang on Android page.

Windows, Mac and Chromebook: the browser extension

On a computer the "download" is the Web Reader extension, the part of Readlang people praise most: any page you are already reading becomes clickable text.

• Chrome. Search the Chrome Web Store for "Readlang Web Reader" and click Add to Chrome. The listing shows about 100,000 users.
• Edge. Edge is built on Chromium, so you install the same extension from the Chrome Web Store; Edge asks once whether to allow extensions from other stores.
• Firefox. A separate extension has existed since November 2025 at addons.mozilla.org. It is small but maintained; the listing was updated in September 2026.
• Safari on a Mac. No extension. Readlang offers a bookmarklet, which requires allowing third-party cookies in Safari and is the least smooth of the four.
• Chromebook. Chrome on a Chromebook installs Chrome Web Store extensions, so the Chrome route applies unchanged.

After installing, sign in at readlang.com once; the extension uses that session. Open any page in the language you are learning, click the Readlang icon, and click a word. Browser by browser detail, including the Safari cookie setting, is on the Readlang extension page.

What the "Readlang app" in the App Store is

Search the App Store for Readlang and you get results, which is where the confusion starts. None of them is published by Readlang.

Readlang Mobile is the app we make. It is a native iOS reader for iPhone and iPad on iOS 18 and later, built for the same habit: tap a word while reading and the translation appears in the sentence; tap the first and last word of a phrase and the phrase is translated whole. It is an independent product from a different developer. It is not affiliated with, endorsed by or connected to Readlang. Your Readlang login does not work in it, and it cannot import a Readlang word list. The two products are set side by side on the Readlang vs Readlang Mobile page.

ReadLang WatchLang, which appears on Google Play and in the App Store, is a third product from yet another developer. It is not Readlang and it is not ours. The shared name is the only thing the three have in common.

The reliable test: readlang.com links to no app store, and the only mobile instruction Readlang publishes is the home-screen shortcut above. Anything in a store carrying the name was made by someone else.

APK, mod and "premium unlocked" downloads

Searches for "readlang apk", "readlang premium apk" and "readlang mod" lead to file-sharing sites promising a Readlang app with Premium switched on. There is no such file: Readlang has never published an Android app, so there is no APK to crack. Whatever those sites host is a thin wrapper around the website with someone else's code inside, or an unrelated app renamed.

A "premium unlocked" version is also impossible in principle. Premium is a subscription attached to your account on Readlang's servers; the phrase limit and the AI limit are checked there, not on your phone. A modified file cannot change what the server allows. The realistic outcomes of installing one are typing your Readlang password into an app you know nothing about, injected ads, or malware, with no update path when it breaks.

If the goal is Readlang on Android, use the two free routes above. If the goal is not paying, the free plan already gives unlimited single-word translations and ten phrases a day.

What a native app gives that a shortcut does not

For many readers the home-screen shortcut is enough, and nothing on this page should talk you out of an account you like. Where a native app differs is in three specific places.

• Translation on the device, if you switch to it. By default, translation comes from Google Translate through the app's server; in Settings you can switch to Apple Translate, which runs on the device.
• Offline. Without a connection the app switches to Apple Translate, which translates on the device if the language pack for your pair is downloaded; a book has to be opened online once.
• A graded library. Public-domain books sorted from A1 to C1, some with narration and the current word highlighted, so the first book is not a wall of text. Your own EPUB files can be added on Premium.

The trade-offs are just as specific. Readlang Mobile covers the roughly twenty languages Apple Translation supports on the device, against Readlang's hundred-plus. It has no browser extension, no YouTube player, no spaced-repetition flashcards and no CSV export, and it runs only on iPhone and iPad; there is no Android version. The free plan allows 30 translations a day with phrases up to six words; Premium is $8.99 a month or $59.99 a year through the App Store.
