Voice chat on Mumble servers
About this app
A client for the Mumble voice chat system. Host or connect to one of the many community run public servers (see https://www.mumble.info). Mumla is an updated and maintained version (a fork) of the app Plumble.
Some of the features:
* Certificate generation, import and export * Browse public servers * Voice activated transmission (the default), or different Push-to-talk buttons * Bluetooth headset support * Self-registration on server * Access tokens * Opus, CELT, and Speex codec support * Automatic reconnection * Tor support through the Orbot app * Text-to-speech for messages (turned on by default) * Light and dark theme
Voice activated transmission currently works best when using a headset. Echo cancellation and noise reduction needs work. Tweaking the Detection threshold in the settings helps.
Mumla is copylefted libre software. Find out more at: https://mumla-app.gitlab.io/

- A lot of work was done to update Mumla for Android 15 and 16 (API 35 & 36). As a consequence Android 5.0 (API 21) or later is now required. Theming was modernized to support system light/dark modes. The settings screen had to be adapted to newer APIs. Added in-app language preference.
- The languages available in Mumla are those which have been translated to 40% or more.
- You can help translating Mumla at https://hosted.weblate.org/engage/mumla/

Installation Guide
Open Settings on your Android device
Go to Security → Unknown sources (or Install unknown apps)
Enable "Allow from this source" for your browser or file manager
Open the downloaded APK file from your Downloads folder
Tap "Install" and wait for installation to complete
Launch the app from your home screen
Make sure to re-enable Unknown Sources restrictions after installation for security.
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 se.lublin.mumla 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, 3.7.1 is the last build before it. Android will not install an older version code over a newer one, so you must uninstall Mumla 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 Mumla, and a listing is removed when the evidence for it stops holding up.

The signing certificate fingerprint for this release is on record, so a build that does not match it did not come from this publisher.
