@Gargron I'm not keen on Signal. The UI itself seems alright. What I'm not a fan of is the management/leadership.

A privacy app built for "privacy" should be very easy to download without an app store, yet they promote getting it from known app stores. They also anchor fear to the standalone APK download for android, labelling it the "Danger Zone". If the app and service is as secure and trustworthy as perpetuated than why anchor fear to the non-app store version?
