in Links – The Beautiful & Secure Messenger

We’re building a message app where no one can listen in, not even us. We would rather close down the service before letting anyone in.

This seems like a noble and well-worth effort, but I can’t help to think that even though the guys at create a secure messaging application, how do you know that you are downloading the exact version from the AppStore that they created, and not a modified version with a backdoor?
