Voxer (, iOS) takes a more voice-oriented approach than a lot of these other apps, allowing users to send voice messages similar to a walkie-talkie or push-to-talk device. Users can listen to messages live in-app or play back messages like voice mail later on; they can also send and receive text, photos, videos, and location messages. In addition to direct messaging, the app supports groups of up to 500 individuals, and optional encrypted messaging using the Signal protocol. The app is free, but a premium subscription unlocks features such as unlimited message history, message recall, admin controls for group chats, a hands-free walkie-talkie mode, and an option for an extra loud Extreme Notifications mode for noisy environments.
