    I like the app basically. BUT on Windows Phone it is terribly buggy. Messages get constantly lost - even messages I sent myself. Notifications and Messages are often out of sync. Most messages containing photos can't be read. Last update has been rolled our months ago. I seems to me as if the Windows Phone port has been abandoned.

    This is the ONLY privacy-focused encrypted communication app that I've found that DOESN'T require you to give up your phone number. It also lets you add PEOPLE IN PERSON manually WITHOUT NEEDING TO SCAN YOUR CONTACT LIST or leave any other unnecessary digital footprints. For that it gets 5 stars. Sure it might not look as good as some other apps out there, and the Windows Phone version is of course lagging behind the Android and iOS versions in the feature/customization department (like using your own photos for the chat background, or being able to nuke all data after a certain number of failed lock screen attempts), but it has it where it counts.

  • Threema Review

    Threema uses any trusted open source NaCl cryptography library for encryption. Jan 21, 2016 - The three “E”s were a bit unwieldy, so it became “Threema”. The encryption keys are generated and safely saved with user's devices if you want to be able if you want to prevent backdoor entry and copies.
