Private, anonymous messaging with solid encryption.
Threema is serious about maintaining their user's security and privacy. Their messaging and voice calling are both end-to-end encrypted, and you can sign up anonymously without a phone number or email address. Not having the secret keys to user accounts, Threema doesn't have the ability to see the content of your messages. In addition to their robust security, you can also create polls, transfer files, record audio, change your theme, and share your location.
Based in Switzerland, Threema should be considered by anyone looking for a secure, feature-rich messenger.

Threema has some bells and whistles, but is missing staples like video calling, GIF integration, and stickers.
While positive overall, there are places where the user experience could definitely benefit from refinement.
Threema's design feels busy. It's not a deal-breaker, but it's certainly lacking some elegance.
