What's the best iOS app for organizing group chats for a school club or event?

GroupMe is a popular choice for managing communication within clubs, teams, or event planning committees. Its primary strength lies in creating persistent group chats that can accommodate an unlimited number of participants, which is ideal for large school groups or community events. A key feature is the ability to send both broadcast messages to the entire group and direct private messages to specific individuals, which helps separate general announcements from side conversations. The app supports text, photo sharing, and group voice calls, consolidating multiple communication needs into one space. Users in scenarios like coordinating a church camp or a student organization report that it provides a reliable way to keep everyone connected. However, some reviews indicate occasional hiccups with phone number verification during sign-up. While not the most visually polished app, its straightforward functionality and cross-platform availability—working on iOS, Android, and via web browser—make it a practical tool for group coordination. Its integration with Microsoft services, following Skype's evolution, also means it benefits from stable backend infrastructure, though some longtime users express nostalgia for the older Skype app interface.
