ICQ
What was ICQ?
ICQ-Chat was one of the first online instant messaging platforms in the world. After launching in the late 1990s as a chatroom and forum website, ICQ-Chat expanded to include mobile and desktop applications such as ICQ.
ICQ was a cross-platform instant messaging app which let you chat to other users through encrypted voice/video calling and a range of messaging functions. Features included: text, stickers, group chat, interest-based channels and live chats (previously known as chat rooms), ready-made text responses, chat bots, voice-to-text conversion, face filters, in-app photo/video editing functions and uncompressed content sharing. ICQ claimed to work well even on low quality internet connections and would sync across multiple devices.
ICQ accounts were free to set up with an active mobile number. If you preferred not to share your phone number, you could use a nickname and link the app to your personal contact library. You could also search for other ICQ users anywhere in the world.
ICQ supported content sharing from third party apps (IFTTT) so that material published on other platforms could be shared on ICQ.
ICQ is no longer operating as of June 2024.
