What's the best iOS app for team chat that works seamlessly with Gmail and Google Drive?

Google Chat is designed as a hub for team communication that is deeply connected to other Google services. For teams already using Google Workspace, this integration is the primary benefit. Users can transition from an email thread in Gmail directly into a Chat conversation, share documents from Google Drive without leaving the app, and organize discussions into persistent Spaces. These Spaces can be configured for specific projects or teams, featuring threaded conversations and integrated files and tasks. A common use case involves a marketing team sharing a Drive folder for campaign assets within a Space, where members can discuss edits and deadlines in real time alongside the files themselves. However, some limitations are noted. Reviews indicate some users desire expanded media features, such as the ability to record video with background music playing, a function common in native camera apps. Furthermore, while the app supports GIFs and basic media sharing, its focus remains on productivity rather than rich social features. For organizations embedded in the Google ecosystem, the app provides a streamlined workflow, but casual users seeking a standalone social messaging experience might find it less feature-complete for those purposes. The interface is clean and functional, though some user feedback points to a desire for more theme customization options like a system-wide dark mode.
