In-app Chat
In-app Chat is a messaging feature built directly into mobile applications that allows users to communicate with each other or with customer support without leaving the app. In ridesharing applications, this is particularly important as it lets drivers and riders message each other about pickup locations or delays. Think of it like text messaging, but specifically designed to work within the app itself. Companies often use ready-made chat solutions like Intercom or Zendesk, rather than building the entire system from scratch.
