Secure IM with PQC support

Free · Designed for iPad

SKI+ v2 is an end-to-end instant messaging app with in-depth support of post-quantum encryption algorithms. Message encryption and decryption are completed on the user's device, and the server has no access to these details. Therefore, it provides users with a more privacy-protected messaging system.
