Dear Wikiwand AI, let's keep it short, summarize this topic like I'm... Ten years old or a College student

WhatsApp (also called WhatsApp Messenger) is an internationally available freeware, cross-platform, centralized instant messaging (IM) and voice-over-IP (VoIP) service owned by American company Meta Platforms.[11] It allows users to send text and voice messages,[12] make voice and video calls, and share images, documents, user locations, and other content.[13][14] WhatsApp's client application runs on mobile devices, and can be accessed from computers.[15] The service requires a cellular mobile telephone number to sign up.[16] In January 2018, WhatsApp released a standalone business app called WhatsApp Business which can communicate with the standard WhatsApp client.[17][18]
