Use your Android like a walkie-talkie

HeyTell is the perfect way to stay connected with friends and family who are far away. With the press of a button, you can instantly talk to anyone who has the app, no matter what device they’re using. The best part is that it’s completely free to use, and the audio quality is excellent. You can also use the Voice Changer feature to add some fun to your conversations or create a 25-way chat with Groups.

The app is free and lightweight. Data usage is lower than sending an email, making it more efficient. You can also set notifications so you can receive alerts when someone left you a message.
