twinme+ private messenger vs SimpleX Chat

twinme+ is a premium version of twinme private messenger, a secure instant messaging and High-Definition voice/video call application, protecting privacy by design, and giving users full control over each of their relations and exchanged content. In addition to all the functions and services offered by twinme, twinme+ offers the following features: - "Spaces" to organize your profiles, relations, conversations, notifications, appearance and parameters, according to each social group you interact with. Different Spaces can be used for interacting with your family, friends, colleagues, sport mates, etc.; You can even create "Secret Spaces", which do not appear in the list of Spaces and can only be opened by typing their name (do not forget that name as it will be impossible to retrieve); - "Ephemeral messages", ie messages which disappear at both ends after a certain time; - Option to lock/unlock the application using your device biometric or pin locking services; - Option to prevent a contact from making voice/video calls; - Streaming your music during calls; - Launching group calls; - Inviting additional contacts to join an on-going voice/video group call; - Transferring an on-going voice/video call from a mobile to a PC; - Publishing QR-codes from the calls tab that allow guests to call you without installing the application (click-to-call).

SimpleX Chat advantages: - privacy of your identity, profile, contacts and metadata: unlike any other existing messaging platform, SimpleX uses no phone numbers or any other identifiers assigned to the users - not even random numbers. This protects the privacy of who you are communicating with, hiding it from SimpleX platform servers and from any observers. - complete protection against spam and abuse: as you have no identifier on SimpleX platform, you cannot be contacted unless you share a one-time invitation link or an optional temporary user address. - full ownership, control and security of your data: SimpleX stores all user data on client devices, the messages are only held temporarily on SimpleX relay servers until they are received. - decentralized proxied peer-to-peer network: you can use SimpleX Chat via your own relay servers and still communicate with people using pre-configured or any other SimpleX relay servers. - fully open-source code. You can connect to anybody you know via link or scan QR code (in the video call or in person) and start sending messages instantly - no emails, phone numbers or passwords needed. Your profile and contacts are only stored in the app on your device - relay servers do not have access to this information. All messages are end-to-end encrypted using open-source quantum resistant double-ratchet protocol; the messages are delivered via relay servers using open-source SimpleX Messaging Protocol.
