The app also supports channels for broadcasting messages to large audiences. Beyond file sharing, Potato Chat provides standard messaging features like text, voice messages, and video calls. While it might not have the largest user base compared to other messaging apps, its focus on file sharing and group communication makes it a practical choice for specific needs. Users appreciate the app's ability to handle large files without compression, ensuring quality is maintained when sharing media.
