Threema delivers a similar service with a few more features. It also 

has end-to-end encryption, which is applied to all communication 

including text messages and files and images sent via the service. 

There’s no voice call capability, but users can send voice messages. 

Both sender and recipient must have Threema installed

​;

Additionally, Threema allows users to hold group chats and to pose 

a question as a poll to group members. There’s no need to open an 

account to use the app, because each user is assigned a random ID 

that isn’t necessarily connected to an email address or phone number;
