Adds Pinyin or Cantonese etc to websites and EPUBs
About this app
This browser app adds Mandarin Pinyin, or Cantonese, Teochew or Wenzhou pronunciation guides, to any Chinese website or EPUB file or to the clipboard, to help people who are learning Chinese to read articles. You can also tap on any word to see an English translation of that word. Changing the website's layout to add Pinyin is not perfect (some websites work better than others), but it still works a lot of the time. For privacy, this app does NOT use any third-party server to fetch or process your text: pinyin is added by your device only. This also means you must be able to fetch the article via your own network connection, or provide the text yourself, before this app can show it. Can integrate with Pleco or Hanping. Has 3lines mode (if you must), Bookmarks, Highlighting and PDF export, Change text size across all pages, Dark mode. Lightweight and some features work on very old devices too.

How to install this safely
How to verify the file you downloaded
Before you install anything, confirm the file is the one described here. On a computer, run shasum -a 256 your-download.apk (macOS or Linux) or certutil -hashfile your-download.apk SHA256 (Windows), then compare the output character-for-character with the SHA-256 on this page. If a single character differs, the file is not the build we recorded — delete it.
What the signing certificate proves
Every Android app is signed with a private key that only its developer holds. The fingerprint on this page is a hash of the matching public certificate, and it proves continuity rather than identity: it tells you a build came from whoever signed the earlier ones. Android enforces this at install time — if a package claiming to be org.ucam.ssb22.pinyinfdroid is signed with a different key, the system will refuse to install it over your existing copy. A fingerprint that changes between releases is worth pausing on, because a repackaged app that has been modified by someone else cannot keep the original signature.
How to roll back to an earlier version
If the current release misbehaves, 2.12.67 is the last build before it. Android will not install an older version code over a newer one, so you must uninstall Pinyin Web & EPUB and topolects first — which clears its local data unless you have a backup. Reinstall the older APK only if its signing fingerprint matches the build you already trust, and check the API range: an older release may target an Android version your device has moved past.
Why we list sources instead of hosting everything
The official store channel is almost always the right choice: it updates automatically and carries the publisher's own distribution guarantees. A direct APK is useful when a device has no store access, when a rollout has not reached your region, or when you need a specific version — and only when the publisher has authorized that copy. APKBrowse does not list pirated, cracked, or unauthorized rebuilds of Pinyin Web & EPUB and topolects, and a listing is removed when the evidence for it stops holding up.
