Groups and distribution lists allow to send messages to multiple recipients at once. Groups are managed in a strictly decentralized manner. Except the group members themselves, no one – not even Threema – knows who is member of a group.
Thanks to the desktop app and the web client, chatting from the desktop is just as secure as using the Threema app on your phone. You have full access to your entire chat history as well as all contacts and media files.
Use Threema to send any type of file. Just like text messages, files are end-to-end encrypted, of course.
Create polls in no time to gather the other group members’ opinions in an efficient manner.
Place calls without revealing your phone number. Threema calls are end-to-end encrypted and thus tap-proof. They impress with crystal-clear voice quality and brilliant video quality.
Invite the members of a group chat to join an end-to-end encrypted audio/video group call by tapping a single button.

Select the theme of your liking: light or dark.
Use Threema on tablets and devices without a SIM card.
