“Zello” promises to turn you phone or tablet into a walkie talkie with it’s lightning fast speed and free push-to-talk feature. Push a button, record your message, and send over a wi-fi or data network like you do with a walkie talkie. You can set it up to talk with others privately or create or join a larger public group. Zello is free for iOS, Android and Windows phone.
Aptly named “Roger” is another app with walkie talkie-like features. Just push the big simple button, record your message, and send. The Roger app lets you see the location, weather and time of day of the person who is receiving your message. All you need to know is the phone number of the person you want to start communicating with via Roger. Recipients don’t even need the app installed on their device. The app is for iOS and Android.
“Voxer” also has the ability to deliver short recorded messages. You can decide to listen to messages when they’re delivered or wait until you’re in a more private setting. You can also see the locations of others through Voxer. Send them a photo, videos and your location. Voxer is free for iOS, Android and Windows phone.
