6. The Briar apk name should contain the version number in the name as well
Download the Briar app for Android here: https://briarproject.org/apk/briar.apk
In the name is no version number. it's just: briar.apk
Perhaps more details should be added to better organize your apk library faster and more accurately.
Like this, for example: Briar v1.2.4.apk or Briar-1.2.4.apk
