We compared the signing certificate of this build with the certificate recorded the first time dev.linwood.butterfly.nightly entered the site, and published both the file's SHA-256 and the certificate's fingerprint above so you can check the download yourself. That comparison says the file was not repackaged by someone else; it is not a review of what the app does.
The manifest inside the APK declares 8 permissions, including access to the camera and the microphone. Android asks you to approve those the first time the app needs them.
Its licence is AGPL-3.0-only. We took this build from F-Droid, and the source for this exact version is linked below.
We do not show a star rating or an install count for this page: we have no measured figure for either, and a number we cannot source is worth less than an empty field.
