Chat & Instant Messaging (214 programs)

Pros: End-to-end encryption for messages, calls, and file transfers. Group chats support up to 100,000 members. Message history synchronised across up to six linked devices. Anonymous ID option hides phone numbers from contacts.

Cons: Notifications require manual system and in-app configuration. Some users report occasional performance lag during peak usage. High notification volume demands careful management in massive groups.
